What is Radiofrequency ablation catheter: Uses, Safety, Operation, and top Manufacturers!

Introduction

A Radiofrequency ablation catheter is a sterile, catheter-based medical device designed to deliver controlled radiofrequency (RF) energy to targeted tissue, creating a localized thermal lesion (ablation). In many hospitals, it is most commonly associated with cardiac electrophysiology (EP) procedures, but the exact clinical use depends on the device design, labeling, and local practice.

This clinical device matters because it sits at the intersection of high-acuity patient care, specialized teams, and complex infrastructure: RF generators, mapping platforms, imaging, irrigation systems, and strict safety and infection-control processes. It is also a “high-impact consumable” in many service lines, meaning outcomes, throughput, and cost-of-ownership are strongly influenced by correct selection, setup, and standardization.

This article provides general, non-clinical guidance on what a Radiofrequency ablation catheter is, where it is used, how it is typically operated, how teams manage safety, how to interpret common device outputs, what to do when issues occur, and how procurement and operations leaders can think about the global market. It does not provide medical advice; clinical decisions should follow local protocols, clinician judgment, and the manufacturer’s Instructions for Use (IFU).

What is Radiofrequency ablation catheter and why do we use it?

Clear definition and purpose

A Radiofrequency ablation catheter is typically a flexible, steerable catheter with one or more electrodes near its distal tip. When connected to an RF generator (and, in many configurations, a patient return electrode), it delivers RF energy into tissue. The energy converts to heat in the tissue (via resistive and conductive heating), producing a controlled lesion intended to interrupt abnormal electrical pathways or modify tissue behavior.

Depending on specialty and product design, a Radiofrequency ablation catheter system may include:

A catheter with tip and ring electrodes (and sometimes multiple electrodes)
Temperature sensing (varies by manufacturer)
Irrigation capability to cool the electrode–tissue interface (varies by manufacturer)
A handle with deflection controls for navigation
Connector cables to an RF generator and, where applicable, to mapping/recording systems
Optional sensors (for example, contact-force sensing), where available and indicated

From a hospital operations viewpoint, the catheter is only one component of a broader medical equipment ecosystem that may include a mapping system, recording system, fluoroscopy, ultrasound, anesthesia support, irrigation pump, and hemodynamic monitoring.

Common clinical settings

The most widely recognized setting is the cardiac EP laboratory, where RF catheters are used in procedures intended to treat arrhythmias such as atrial fibrillation and various supraventricular or ventricular tachycardias. In this environment, the catheter is navigated through vascular access to intracardiac targets under imaging and/or electroanatomic mapping guidance.

In other specialties, “radiofrequency ablation” may be delivered through differently shaped probes or cannulas rather than a steerable EP catheter. Whether those are categorized or procured as a “catheter” depends on local naming conventions and the manufacturer’s product family. In all cases, intended use is defined by the IFU and regulatory labeling, which vary by manufacturer and country.

Key benefits in patient care and workflow

While benefits depend on indication and patient selection, hospitals typically value Radiofrequency ablation catheter programs for several operational and care-delivery reasons:

Minimally invasive approach compared with open surgical alternatives in many contexts
Targeted therapy with real-time procedural feedback (signals, impedance, temperature, contact metrics), where supported
Repeatability and standardization through protocols, checklists, and structured documentation
Potential for reduced length of stay in appropriately selected pathways (varies by institution and indication)
Service-line scalability when lab utilization, staffing, and supply chain are well-managed
Compatibility with advanced platforms (mapping, imaging, navigation) that can improve workflow consistency, depending on the installed base and training

Administrators and biomedical engineers often focus on a second set of benefits: predictable consumable management, clear device traceability (lot/UDI), and the ability to align capital equipment and disposables into a cohesive, supportable fleet.

When should I use Radiofrequency ablation catheter (and when should I not)?

Appropriate use cases (general)

A Radiofrequency ablation catheter is typically used when:

The clinical team intends to create a controlled lesion at a specific anatomical target under appropriate procedural guidance
The facility has the necessary infrastructure (lab environment, monitoring, imaging, and emergency response capability)
The selected catheter and RF generator are labeled for the intended use in that jurisdiction
Staff are trained and credentialed per institutional policy and manufacturer requirements

In cardiac EP, typical use involves targeting arrhythmogenic tissue based on electrogram signals and mapping. In other settings, the same underlying energy principle is used to thermally ablate tissue under imaging guidance, but device design, accessories, and workflows can differ substantially.

Situations where it may not be suitable

A Radiofrequency ablation catheter may be not suitable or may require heightened caution when:

The clinical environment cannot reliably provide required monitoring, imaging, and emergency response capability
Necessary accessories (e.g., compatible generator, cables, irrigation system, return electrode) are not available or cannot be verified as compatible
The team cannot confirm device integrity, sterility, traceability, or proper setup
The facility cannot meet required infection-control standards for intravascular or sterile procedures
There is insufficient trained staffing (including coverage for complications, escalation, and post-procedure monitoring)

From an operational perspective, a key “do not” is using a catheter outside the ecosystem it is intended for (wrong generator, wrong cables, wrong mapping interface). Even when physical connectors appear similar, compatibility is not assured and may create safety and liability risks.

Safety cautions and contraindications (general, non-clinical)

Contraindications and warnings are device- and indication-specific and must be taken from the IFU. Common categories of cautions that frequently appear in RF ablation systems include:

Electrical safety: risk of unintended burns, particularly at the return electrode or at alternate current pathways
Thermal injury: risk to adjacent structures from heat spread, especially in sensitive anatomical regions
Embolic risk: risk of thrombus/char formation depending on technique, monitoring, and device design
Device interaction risk: potential interactions with implanted electronic devices or monitoring equipment (varies by manufacturer and clinical context)
Material compatibility: potential sensitivity or allergy considerations based on catheter materials and ancillary products
Imaging and radiation: if fluoroscopy is used, there are occupational and patient radiation safety considerations

For non-clinical readers: the key point is that a Radiofrequency ablation catheter is not “plug-and-play” hospital equipment. It is a specialized, energy-delivering device whose risk profile depends on correct integration, training, and adherence to labeled use.

What do I need before starting?

Required setup, environment, and accessories

At a high level, a Radiofrequency ablation catheter program typically requires:

A suitable procedure room (often an EP lab or catheterization lab) with sterile workflow capability
Physiologic monitoring (ECG, blood pressure, oxygenation; exact requirements vary by procedure type)
Imaging capability as appropriate (often fluoroscopy; sometimes adjunct imaging such as ultrasound; varies by institution and indication)
An RF generator compatible with the catheter
A compatible patient return electrode (for many unipolar systems) and proper skin preparation supplies
Connection cables, footswitch (if used), and interface modules as required by the system design
If applicable, an irrigation pump/system and compatible tubing/fluids (varies by manufacturer)
Emergency equipment (e.g., defibrillator, airway equipment) per facility protocol for high-acuity procedures
A method to capture and store procedure data (recording system, EMR documentation, device logs) consistent with policy

Procurement teams should treat the catheter as part of a system-of-systems. Even when the catheter is the primary consumable, the accessories and installed base determine whether the program can run safely and efficiently.

Training and competency expectations

Competency is not only about physician technique. Safe operation relies on coordinated performance by multiple roles:

Clinicians trained in the procedure and in RF energy principles
Nursing and technologist teams trained in sterile technique, monitoring, alarm response, and workflow
Anesthesia or sedation support according to institutional practice (varies by procedure)
Biomedical engineering trained in electrical safety, generator checks, accessory compatibility, and incident response
Supply chain staff trained in lot/UDI capture, storage conditions, expiry management, and recall workflows

Training expectations may include device-specific in-servicing, simulation, proctored cases, periodic competency reassessment, and documented sign-off. Exact requirements vary by manufacturer, jurisdiction, and facility.

Pre-use checks and documentation

A practical pre-use checklist typically includes:

Verify outer packaging integrity and sterile barrier (no tears, moisture, punctures)
Verify device label: intended use, size/curve/shaft options, and compatibility notes
Check expiry date and storage conditions per label
Capture and record UDI/lot/serial information according to policy
Inspect catheter and cable connectors for visible damage before sterile presentation (as permitted by packaging)
Confirm RF generator self-test status and electrical safety readiness
Confirm required accessories are present: return electrode, cables, irrigation set, mapping interface (as applicable)
Confirm alarms are enabled and audible, and that staff know who responds to which alarm
Ensure the room has a clear escalation pathway (biomed on-call, manufacturer support process, adverse event reporting process)

From a governance standpoint, consistent documentation is also how hospitals defend safety and quality: traceability, standardized workflows, and the ability to investigate any adverse event or near miss.

How do I use it correctly (basic operation)?

The following is a general workflow. Exact steps, connections, and settings vary by manufacturer and by procedure type. Always follow the IFU and facility protocol.

Basic step-by-step workflow (high level)

Room and team preparation
Confirm procedure plan, roles, sterile field setup, monitoring readiness, and emergency equipment availability.
System setup
Power on the RF generator and any associated systems (recording, mapping, irrigation). Confirm correct software profiles or procedure modes if applicable.
Accessory connection and verification
Connect required cables, footswitch (if used), return electrode lead, and irrigation set (if applicable). Confirm the system recognizes connected components, where that feature exists.
Patient return electrode application (if applicable)
Apply the return electrode per manufacturer guidance and facility protocol. Placement and skin preparation are safety-critical steps in unipolar RF systems.
Catheter preparation
In the sterile field, prepare the catheter as required (e.g., flushing lumens, priming irrigation, confirming handle movement). Avoid kinking, crushing, or contaminating the sterile device.
Calibration or baseline checks (if relevant)
Some platforms require baseline steps such as confirming signal quality, verifying temperature sensing, or zeroing contact-force measurements. This is varies by manufacturer.
Catheter introduction and navigation
Introduce the catheter through appropriate access hardware and navigate under imaging and/or mapping guidance. Maintain awareness of catheter torque, deflection, and potential resistance.
Target identification and stability checks
Identify target tissue using available information (electrograms, mapping geometry, imaging). Confirm stability and intended contact before energy delivery.
Energy delivery (ablation)
Deliver RF energy under the selected control mode. Monitor system outputs (power, impedance, temperature, time, irrigation status) and patient status continuously. Adjustments are made according to clinician judgment, protocol, and IFU.
Assessment and documentation
After energy delivery, document key parameters, outcomes, and any device issues. Confirm endpoints according to the clinical plan.
Device removal and disposal
Remove the catheter and dispose of single-use items per policy. Preserve traceability documentation and any device logs.
Post-procedure equipment reset
Clean and disinfect reusable non-sterile components (e.g., cables, generator surfaces) per policy and prepare the room for the next case.

Setup, calibration, and operation details that commonly matter

Even without giving clinical instructions, there are operational elements that repeatedly drive safe performance:

Compatibility confirmation: Catheter–generator–cable compatibility must be verified at setup, not assumed.
Cable management: Poor cable routing can cause disconnections, contamination risk, or signal noise.
Irrigation readiness (if applicable): Confirm priming, correct tubing routing, absence of occlusions, and correct fluid selection per IFU.
Return electrode readiness (if applicable): Confirm placement, adhesion, and system sensing (where supported).
Signal quality: Poor electrogram signals can lead to incorrect targeting or repeated ablations, impacting safety and efficiency.

For biomedical engineers, this is also where preventive maintenance and pre-case verification matter: generator performance checks, alarm function checks, and any manufacturer-required periodic inspections.

Typical settings and what they generally mean (conceptual)

Most RF ablation systems expose some combination of the following adjustable or displayed parameters:

Power (Watts): The rate of energy delivery. Higher power generally increases heating rate, but settings and safe use depend on catheter type, irrigation, target tissue, and protocol. Exact ranges and recommended values are varies by manufacturer and indication.
Temperature limit (°C): A control or safety limit based on measured temperature at or near the electrode. In irrigated designs, measured temperature may not reflect deeper tissue temperature.
Time/duration: How long energy is delivered for a given application. Many systems allow manual or timed delivery.
Impedance (Ohms): A measure of electrical resistance in the circuit. Trends (rather than a single number) are often used to infer contact quality and tissue heating, but interpretation is context-dependent.
Irrigation flow rate (if applicable): Used to cool the electrode and reduce surface overheating. This can influence lesion formation and system temperature readings.

Some manufacturers also provide composite metrics (sometimes described as lesion indices) that combine multiple inputs. The meaning, validation status, and appropriate use of these indices are varies by manufacturer and should be governed by local policy.

How do I keep the patient safe?

Patient safety in RF ablation is a system outcome: equipment integrity, standardized workflow, trained staff, vigilant monitoring, and disciplined response to alarms and unexpected events.

Safety practices and monitoring (general)

Common safety practices include:

Use a pre-procedure time-out to confirm identity, procedure type, and equipment readiness
Ensure continuous physiologic monitoring appropriate to the case and facility policy
Confirm availability of emergency response equipment and clear escalation roles
Maintain strict sterile technique and minimize line/cable clutter to reduce contamination risk
Standardize documentation of key device parameters and events to support quality review

Safety monitoring is broader than the RF generator display. It includes patient physiologic data, access-site status, fluid balance (especially when irrigation is used), and signs that equipment function is deviating from expected behavior.

Key RF-specific risks (general categories)

Risks vary by procedure and anatomy, but common RF-system risk categories include:

Unintended burns: Often associated with return electrode issues or alternate current pathways.
Thermal injury to adjacent structures: Heat can affect non-target tissue depending on anatomy and technique.
Thrombus/char formation: Overheating at the electrode–tissue interface can increase coagulum risk.
Perforation or tissue disruption: Mechanical manipulation and thermal effects can contribute to injury.
Fluid-related issues (if irrigated): Irrigation adds fluid load and requires pump/line integrity.
Electromagnetic interference: Interactions with other equipment are possible in complex procedure rooms.
Radiation exposure: If fluoroscopy is used, both patient and staff must be protected under ALARA principles.

The practical operational implication is that safety is not a single control. It is managed through multiple layers: correct setup, correct monitoring, correct interpretation, and prompt response.

Alarm handling and human factors

Alarms are only effective if the team’s response is reliable. Strong practice typically includes:

Assigning alarm ownership (who responds to generator alarms, irrigation alarms, monitoring alarms)
Using closed-loop communication (“Alarm acknowledged; energy stopped; connections being checked”)
Creating a culture where any team member can call a pause if something does not look right
Practicing failure scenarios (e.g., irrigation occlusion, return electrode fault, sudden impedance change) in training or simulation

Alarm fatigue is a real risk in high-technology rooms. Facilities often benefit from standardizing alarm thresholds only where appropriate and ensuring audibility without creating constant non-actionable alerts.

Emphasize facility protocols and manufacturer guidance

Hospitals should explicitly align three layers of guidance:

Manufacturer IFU (device-specific requirements and warnings)
Facility policy (credentialing, monitoring standards, infection control, documentation)
Service-line protocols (procedure workflows, emergency response, device preference cards)

When these layers conflict or are unclear, risk increases. Operations leaders can reduce variability by ensuring protocol updates occur whenever equipment models, software versions, or supply substitutions change.

How do I interpret the output?

A Radiofrequency ablation catheter procedure generates multiple data streams. Interpretation is often shared across clinicians, technologists, and device specialists, but governance and documentation should be facility-owned.

Types of outputs/readings you may see

Common outputs include:

RF generator display: delivered power, time, impedance, and sometimes temperature and mode status
Irrigation system display (if applicable): flow status, pressure or occlusion indicators, and alarm states
Mapping/recording system: electrograms, catheter location, lesion tags, and potentially sensor data (e.g., contact force), where supported
Monitoring systems: ECG rhythm, blood pressure, oxygen saturation, and other physiologic parameters per protocol

Some systems also store case logs that can be exported for quality review. The availability and granularity of logs are varies by manufacturer and by configuration.

How clinicians typically interpret them (general patterns)

In general terms:

Impedance trends may be used as a proxy for circuit integrity, tissue heating behavior, and contact stability. Sudden changes can indicate loss of contact, coagulum formation, or connection issues, but interpretation is not universal.
Temperature readings can help prevent surface overheating in some designs, but in irrigated catheters the measured temperature may be lower than tissue temperature.
Electrogram changes (amplitude, timing, conduction patterns) are often used to judge whether tissue behavior has changed at the target site.
Composite indices (if used) are interpreted within the context of that manufacturer’s algorithm and local validation.

For administrators and biomedical engineers, the key insight is that “numbers on a screen” are not direct measurements of lesion depth or long-term clinical effect. They are operational and physiologic proxies that require context and training.

Common pitfalls and limitations

Assuming inter-system equivalence: impedance, temperature, and indices may not be comparable across different manufacturers.
Over-reliance on a single parameter: safe decisions typically integrate multiple inputs (patient status, catheter stability, output trends).
Misleading baselines: poor return electrode contact, cable issues, or dry connectors can distort readings.
Data capture gaps: if lot/UDI, settings, or events are not recorded reliably, post-event investigation becomes difficult.

What if something goes wrong?

When issues occur, teams need a clear boundary between “safe to troubleshoot” and “stop and escalate.” The correct boundary depends on the event type, patient status, and local policy.

Rapid troubleshooting checklist (non-clinical, system-focused)

If performance is unexpected or an alarm occurs, common checks include:

Confirm RF delivery has stopped if the situation is unclear
Check all cable connections at the generator, junction boxes, and catheter handle
Confirm the correct catheter and cable set is being used for that generator model
Inspect for visible cable damage, fluid ingress, or connector contamination
Verify return electrode connection and placement integrity (if applicable)
Check whether the irrigation system is running, primed, and free of occlusions (if applicable)
Review generator messages for specific fault codes (document them)
Confirm that patient monitoring leads and grounding are not creating alternate pathways
Evaluate whether signal noise is due to equipment proximity, poor shielding, or loose connectors
If a mapping system is involved, confirm correct catheter selection profile and interface modules

Many problems that look “clinical” at first (e.g., unstable readings) can be caused by basic integration faults. A disciplined checklist prevents repeated resets or unsafe workarounds.

When to stop use

Stop use and escalate per facility policy when:

There is any sign of device damage, overheating, smoke/odor, or fluid in connectors
Alarms indicate a safety-critical fault that cannot be resolved immediately
Sterility is compromised
The system behavior is inconsistent with expected operation and cannot be verified
The patient’s condition requires urgent attention beyond routine troubleshooting

In general, it is safer to pause, document, and escalate than to continue with uncertain equipment performance.

When to escalate to biomedical engineering or the manufacturer

Escalate when:

The generator or accessory equipment presents repeated faults, error codes, or unexplained shutdowns
There is suspected electrical safety risk (return electrode issues, unexpected burns, tripping breakers)
Compatibility is unclear or a new product substitution has been introduced
A device malfunction is suspected and may require investigation or reporting
A recurring issue is affecting case efficiency or outcomes across multiple procedures

Operational best practice is to quarantine the suspect catheter/cable (as policy allows), preserve packaging labels/lot numbers, and capture screenshots or photos of error codes. Reporting pathways should follow local regulation and internal incident management systems.

Infection control and cleaning of Radiofrequency ablation catheter

Cleaning principles

A Radiofrequency ablation catheter used intravascularly is generally considered a critical item from an infection-control perspective. In many product categories, the catheter is supplied sterile and intended for single use. Reuse, reprocessing, or resterilization is typically not permitted unless explicitly allowed by the manufacturer’s IFU and local regulation.

Core infection-control principles include:

Maintain sterile barrier integrity until point of use
Prevent contamination of connectors and hubs in the sterile field
Separate clean and dirty workflows in the procedure room
Ensure traceability for infection surveillance and recall response

Disinfection vs. sterilization (general)

Cleaning removes visible soil and reduces bioburden; it is a prerequisite for any further processing.
Disinfection reduces microbial load; levels (low/intermediate/high) vary by method and intended use.
Sterilization is intended to eliminate all forms of microbial life and is typically required for devices entering sterile tissue or the bloodstream.

For most EP-style Radiofrequency ablation catheter products, the catheter itself is sterile and single-use, so the main cleaning focus shifts to reusable accessories and room surfaces.

High-touch points and shared equipment

High-touch and cross-contamination risk points often include:

RF generator touchscreen/buttons and footswitch surfaces
Irrigation pump controls, clamps, and pole handles
Mapping/recording system keyboards, mice, and touchscreens
Cable junctions and connectors (handled frequently during setup/teardown)
Lead aprons, thyroid shields, and reusable positioning aids
Procedure table rails, ultrasound probes (if used), and monitor controls

Hospitals frequently reduce infection risk by assigning clean/dirty roles, using barrier covers where appropriate, and ensuring consistent wipe-down between cases.

Example cleaning workflow (non-brand-specific)

A practical, non-brand-specific workflow between cases may include:

Don appropriate PPE and follow facility environmental cleaning policy
Dispose of single-use items (catheter, tubing, drapes) in correct waste streams
Wipe visible contamination immediately to prevent drying and difficult removal
Clean and disinfect generator and pump external surfaces using approved disinfectants compatible with plastics and screens
Clean/disinfect reusable cables per IFU (many are wipeable only; immersion may be prohibited)
Address floors and high-touch room surfaces per terminal/intermediate cleaning schedules
Confirm that sterile storage areas remain separated from dirty equipment staging
Document room turnover completion if required by policy

Where third-party reprocessing exists in a country, procurement teams should verify regulatory status, validated processes, and traceability. This area varies widely by jurisdiction and is not publicly stated in a single global standard.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In medical technology, the terms manufacturer and OEM can mean different things depending on context:

The manufacturer is typically the entity that markets the finished medical device under its name, holds regulatory responsibility, maintains the quality management system, and provides official IFU, labeling, and post-market surveillance.
An OEM may produce components (e.g., sensors, connectors, tubing), subassemblies, or even complete devices that are then branded and sold by another company. OEM involvement can be substantial while remaining invisible to the end user.

In some cases, the branded manufacturer is also the OEM. In other cases, production is shared across multiple OEM partners under supplier quality agreements.

How OEM relationships impact quality, support, and service

For hospitals, OEM structures matter because they can influence:

Consistency of supply (component availability, single-source risk)
Serviceability (spare parts access, turnaround time, firmware/software update processes)
Post-market actions (how quickly issues are identified, investigated, and corrected)
Documentation and traceability (UDI capture, lot genealogy, complaint handling)
Training and clinical support (availability of qualified specialists in-region)

When evaluating a Radiofrequency ablation catheter ecosystem, procurement and biomedical engineering often ask not just “who sells it,” but “who is responsible for quality, and who will support it over the device lifecycle?”

Turkey has a strong network of urban tertiary hospitals and an active private healthcare sector, supporting demand for advanced catheter-based therapies. Import dependence for many specialized EP consumables is common, but local distribution and service networks can be well-developed in major regions. Procurement often considers training support, rapid logistics, and integration with existing lab platforms. Access outside major metropolitan areas can be more variable, making regional planning important.

Germany

Germany is a mature European market with high standards for hospital procurement, device documentation, and clinical governance. Demand is supported by an aging population and well-established cardiology and electrophysiology services across many regions. Procurement decisions often consider compliance requirements, service contracts, and lifecycle management under European regulatory frameworks. Access is generally strong, though hospitals still differentiate on throughput, staffing, and technology standardization.

Thailand

Thailand’s market includes advanced tertiary hospitals and a significant private healthcare sector, especially in Bangkok and other major cities. Demand for Radiofrequency ablation catheter procedures is supported by cardiovascular disease burden and investment in modern hospital equipment. Many specialized EP systems are imported, making distributor performance and training capability key procurement considerations. Access can be concentrated in urban centers, with referrals from provincial hospitals for complex care.

Key Takeaways and Practical Checklist for Radiofrequency ablation catheter

Treat the Radiofrequency ablation catheter as part of a complete system, not a standalone item.
Confirm catheter–generator–cable compatibility using documented sources, not assumptions.
Standardize device preference cards to reduce setup variability and missing accessories.
Require documented staff competency for generator operation, alarms, and emergency pause steps.
Capture UDI/lot information for every catheter to support traceability and recalls.
Verify sterile packaging integrity and expiry before opening the catheter to the sterile field.
Keep connectors dry and protected; fluid ingress is a common cause of faults.
Ensure return electrode workflow is standardized when using unipolar RF systems.
Assign clear ownership for responding to RF generator and irrigation system alarms.
Use closed-loop communication for any alarm response or unexpected device behavior.
Confirm irrigation readiness (prime, flow, occlusion status) when using irrigated catheters.
Maintain disciplined cable management to reduce contamination and disconnection risk.
Do not bypass or silence critical alarms without a documented, approved protocol.
Treat unexpected impedance or temperature behavior as a system-check trigger, not a nuisance.
Plan for procedure-room downtime with backup equipment and defined escalation pathways.
Include biomedical engineering in new device evaluations and compatibility risk reviews.
Ensure preventive maintenance schedules exist for RF generators and reusable accessories.
Verify electrical safety and grounding practices for all connected hospital equipment.
Document key device parameters and any deviations to support quality and peer review.
Avoid off-label use and unapproved reprocessing unless explicitly allowed by IFU and regulation.
Separate clean and dirty workflows in the lab to protect sterile supplies and connectors.
Disinfect high-touch surfaces (generator screens, pumps, keyboards) between cases per policy.
Store catheters according to label requirements and protect sterile barriers from damage.
Build procurement decisions around total cost-of-ownership, not unit price alone.
Evaluate vendor support for training, troubleshooting, and in-country service coverage.
Confirm availability of accessories and consumables to prevent case cancellations.
Ensure incident reporting pathways are known, including device quarantine procedures.
Keep error codes, screenshots, and lot numbers when escalating a suspected malfunction.
Create a policy for software/firmware updates and validate workflow after updates.
Align facility protocols with manufacturer IFU and revise protocols after equipment changes.
Use structured checklists for pre-case setup, intra-case monitoring, and post-case teardown.
Plan staff scheduling to ensure experienced coverage for complex cases and complications.
Include infection-control leaders in any decision that changes reprocessing or cleaning workflows.
Monitor inventory turns and expiry risk; ablation catheters are often high-cost consumables.
Validate supply chain resilience for imported products, including lead times and customs delays.
Maintain competency on emergency stop steps and safe shutdown of RF energy delivery.
Confirm reusable cables are cleaned per IFU; many are wipe-only and not immersion-safe.
Ensure data capture is consistent to support outcomes review and operational improvement.
Conduct periodic mock scenarios for alarms, equipment failure, and sterile field breaches.
Require clear handoffs between procurement, clinical teams, and biomed for new product onboarding.
