Intended Use

The Venclose™ Radiofrequency System (Generator and Catheters) is intended for use in endovascular of blood vessels in patients with superficial vein reflux.

Device Story

Venclose RF System consists of digiRF generator and EVSRF catheter; used for endovascular ablation of incompetent superficial veins (e.g., great saphenous vein). Procedure involves percutaneous catheter insertion under ultrasound guidance; generator delivers temperature-controlled bipolar RF energy (460 kHz) to resistive element in catheter tip. Thermal energy heats vein wall to cause irreversible luminal occlusion, fibrosis, and resorption; blood reroutes to healthy veins. Performed in outpatient setting by physician; no general anesthesia required. Output includes thermal energy delivery; healthcare provider monitors procedure via generator touchscreen. Benefits include minimally invasive treatment of venous reflux with reduced recovery time.

Clinical Evidence

No human clinical data provided. Evidence consists of non-clinical bench testing (catheter simulation, temperature, pressure, tensile, and fluid tests) and an animal study. Animal model (veins sized similarly to human) demonstrated successful catheter navigation, ability to reach and maintain target treatment temperatures, and effective vein diameter reduction comparable to predicate devices.

Technological Characteristics

System comprises digiRF generator and EVSRF catheter. Energy: Bipolar RF, 460 kHz, max 24V. Catheter: 6F (2.0mm) diameter, adjustable heating element (10cm or 2.5cm). Materials: Biocompatible, non-pyrogenic (ISO 10993 compliant). Software: Controlled. Sterilization: Catheters provided sterile. Standards: IEC 60601-1, IEC 62304, IEC 62366, ISO 10555-1, EN ISO 13485, EN ISO 14971.

# Device Description:

The Venclose RF System is composed of two basic components: an energy console or generator (digiRF) and catheters (EVSRF) designed specifically to be used with the generator. The Venclose RF System uses resistive radiofrequency ablation via energy delivery to heat the wall of an incompetent vein with temperature-controlled RF energy to cause irreversible luminal occlusion, followed by fibrosis and ultimately resorption of the vein. The blood then naturally reroutes to healthy veins.

The technique involves percutaneous access and insertion of the EVSRF Catheter into the great saphenous vein (GSV) or other superficial vein under ultrasound guidance, injection of local anesthesia, and thermal energy from a radiofrequency generator (digiRF) applied into the target vein. As the EVSRF Catheter is withdrawn stepwise down the treated length of the vein, thermal damage is inflicted upon the venous endothelium and through the vein wall, resulting in contraction and ultimately destruction of the vessel. The procedure can be performed in an outpatient setting, without the need for general anesthesia, allowing for a walkin/walk-out procedure with minimal postoperative recovery time.

# Materials:

Materials for use in the console are consistent with industry practice for durable cases containing electronic elements. The console is supplied in a non-sterile condition and is not intended to be in contact with the surgical field or the patient. The catheters are made of industry-typical, biocompatible, nonpyroqenic materials and are provided packaged in a sterile condition. They are intended for use in a sterile surgical environment and will make contact with the patient. Biocompatibility data demonstrates that the catheters are in compliance with ISO 10993.

# Comparative Summary of Technological Characteristics:

The materials, design, energy source, software integration, sterility methods (EVSRF Catheter component only), environment of use and clinical applications for the Venclose™ Radiofrequency System are comparable to those identified for the predicate devices.

### Non-Clinical Testing:

Device testing was conducted to evaluate conformance to product specifications and applicable standards.

Bench testing included but not limited to the following tests: Catheter Simulation Test, Temperature Test, Pressure Test, Tensile Test, Fluid Test.

Applicable Standards and Guidances are as follows:

- . Guidance on Premarket Notification [510(k)] Submissions for Short-Term and Long-Term Intravascular Catheters, March 16, 1995.
- ISO 10555-1:2013 Sterile, Single-Use Intravascular Catheters, Part 1: . General Requirements
- EN ISO 13485:2012 Medical devices. Quality management systems. Requirements for regulatory purposes
- EN ISO 14971:2012 Medical devices. Application of risk management to medical devices
- IEC 62304:2006 Medical device software. Software life cycle processes
- . IEC 62366:2008 Medical devices. Application of usability engineering to medical devices
- . IEC 60601-1:2005 Medical electrical equipment Part 1: General requirements for basic safety and essential performance
- IEC 60601-1-6:2010 Medical electrical equipment Part 1-6: General . requirements for safety - Collateral Standard: Usability

# Pre-clinical testing:

Animal testing was conducted in a model previously used for research in endovenous ablation for similar devices. The chosen model provided great saphenous and common jugular veins that are sized similarly to human veins. The purpose of the study was to demonstrate proper functionality of the Venclose System in a pre-clinical environment. Objectives included insertion of the catheter though a sheath into the vein, navigation to the intended treatment site, ability to reach a predetermined treatment temperature within a specified time frame and then to hold that temperature for the remainder of the treatment cycle, and capability of reducing the diameter of the vein by an amount similar to that done with the predicate device. All of the objectives were met resulting in a satisfactory study conclusion.

# Rationale for Substantial Equivalence

Conclusions drawn from the non-clinical bench and animal testing demonstrate that the Venclose System is as safe, as effective and performs at least as safely and as effectively as the legally marketed devices (K040638 and K061373) for the requested intended use as identified in this Summary.
