ClosureFast Procedure

SUPERFICIAL VEIN THERAPIES

OVERVIEW

The ClosureFast™ procedure utilizes patented, overlapping segmental radiofrequency ablation to deliver uniform heat to close the vein. Once sealed, blood is directed to nearby healthy veins. The ClosureFast procedure has been rigorously tested across multiple studies.1-3

INDICATIONS

The ClosureFast endovenous radiofrequency ablation (RFA) catheter is intended for endovascular coagulation of blood vessels in patients with superficial vein reflux. The catheter is provided sterile, and is a single-use, disposable device. These catheters cannot be adequately cleaned and /or sterilized by the user in order to facilitate safe reuse, and is therefore intended for single use. Attempts to clean or sterilize these devices may result in a bio-incompatibility, infection or product failure risks to the patient.

DELIVER PATENTED PERFORMANCE

Gap-free Thermal Ablation

The ClosureFast™ RFA system is the only gap-free thermal ablation system with published long-term clinical data demonstrating safety and efficacy, with a 91.9% closure rate at 5 years.1,2

  • Patented, overlapping segmental procedure2
  • Tumescent anesthesia
  • Less pain and bruising than laser energy treatment3
ClosureFast Procedure Overview

GAP-FREE THERMAL ABLATION

The ClosureFast procedure features a patented overlap of 0.5 cm at each thermal treatment segment, eliminating gaps between segments ― for lasting vein closure.1,2

MODEL SPECIFICATIONS

ClosureFast Catheter

CLOSUREFAST ENDOVENOUS RADIOFREQUENCY ABLATION CATHETER

  • The ClosureFast catheter precisely heats a 7 cm vein segment (or 3 cm for shorter, refluxing vein lengths) in one 20-second interval.
  • The heat provided by the catheter shrinks and collapses the target vein, creating a fibrotic seal and occluding the vessel.
ClosureFast Stylette

CLOSURERFS ENDOVENOUS RADIOFREQUENCY ABLATION STYLET

  • The ClosureRFS stylet is the only intravascular ablation device specifically intended for the treatment of incompetent perforator and tributary veins.
  • This minimally invasive outpatient procedure leaves minimal scarring at the puncture site and can be either the primary treatment or an adjunct treatment using the ClosureFast catheter.
ClosureFast Generator

CLOSURERFG RADIOFREQUENCY GENERATOR

  • The ClosureRFG generator delivers radiofrequency energy to the ClosureFast catheter and the ClosureRFS stylet for the effective treatment of CVI.
  • The controlled feedback mechanism monitors intravascular heat parameters in real time to automatically regulate therapeutic power.
