Venclose Maven™ Perforator Catheter
Venclose™ digiRF™ Generator

Indication for Use

The Venclose Maven™ Catheter is intended for endovascular coagulation of blood vessels in patients with perforator and tributary vein reflux.

Contraindications

The Venclose Maven™ Catheter is contraindicated in patients with thrombus in the vein segment to be treated.

Warnings

Potential impact to active implanted medical devices located nearby the intended treatment location in the lower limbs has not been evaluated. It is recommended not to coil the Venclose Maven™ connector cable directly above active implanted medical devices • The Venclose™ system is not intended to be used with magnetic resonance imaging • Thermal treatment of the vein may damage adjacent sensory or motor nerves. Risk of damage is greater near the calf or if no local anesthetic is used around the treated vein • Treatment of a vein located close to the skin surface may result in a skin burn. Ensure that the proximal end of the heating element is at least 0.5 cm from the skin • Do not treat within the deep venous system. Ensure that the distal tip of the catheter is greater than 0.5 cm from the deep venous system • Treatment of a vein located near the skin surface may result in a skin burn if the skin is not protected with fluid infiltration • Care should be taken to preserve adequate blood circulation, especially for patients with documented peripheral arterial disease • Catheter is for single patient use only. A contaminated catheter may lead to illness or death of the patient. Cleaning damage to the catheter may lead to ineffective treatment or injury. Venclose will not be responsible for any direct, indirect, incidental or consequential damages or expenses resulting from reuse of the catheter • Transcutaneous ultrasound imaging is recommended to confirm and maintain device tip and heating element position in the target vessel. Do not place heating element in a vein valve (for the purpose of restoring valve function) or in the deep venous system • If electromagnetic interference associated with stray energy from the digiRF™ System is encountered, reposition the imaging system and/or the digiRF™ Generator to eliminate such interference. See the “Separations Distances” table in Section 12 in the digiRF™ Generator’s User Manual for further information • Nerve injury may occur from thermal damage to adjacent sensory nerves. Risk of nerve injury may be higher with treatment at or below the calf, or without perivenous fluid infiltration • Flammable agents for cleaning, disinfecting, or as solvents of adhesives shall be allowed to evaporate before using the Venclose™ system • Interference caused by use of the Venclose™ system may adversely influence operation of other electronic equipment.

Precautions

Store in a dry, cool place • Do not bend catheter shaft into a tight radius; kinking of the shaft may render the catheter inoperable • To prevent damage to the guidewire, ensure that the guidewire does not protrude from the catheter tip when inserting catheter into vein • If fluid contacts the Venclose Maven™ cable connector, wipe it clean and dry before inserting into the generator • Do not leave the guidewire within the catheter lumen at the heating element location during treatment as it will cause the guidewire to become stuck within the catheter lumen • Do not advance the catheter against resistance, or vein perforation may occur • Uneven blood pooling or flow along the heating element may result in inconsistent effectiveness and/or may damage the catheter • Do not begin treatment without verifying that the length of heating element that will actively heat remains inserted a length of at least 0.5 cm from the vein access point • The portion of the catheter shaft within 2.0 cm of the heating element may exceed 41 ºC during treatment. Testing of this region has shown that a maximum temperature of 42 ºC can be reached • If the generator stops treatment due to improper heating, remove the catheter and inspect. Replace the catheter if damage is found. Failure to respond to advisory indicators can result in damage to the catheter • If using direct external compression, do not compress the skin closer than 0.5 cm to the heating element or a skin burn may occur • Do not re-advance the catheter and re-treat an acutely treated vein section or it may increase risk of embolism • Do not treat with the heating element within the access sheath or closer than 0.5 cm to the point of skin access or a skin burn, catheter damage or sheath damage may result • The vein wall may be thinner in an aneurysmal segment. To effectively occlude a vein with an aneurysmal segment, additional compression may be needed over the aneurysmal segment, and the treatment of the vein should include segments proximal and distal to the aneurysmal segment • Use of a flush through the catheter while the heating element is active will interfere with treatment and heat the fluid exiting the end of the catheter. Avoid fluid delivery through the catheter when tip of catheter is near an area that should not be thermally coagulated • Failure to evenly compress the vein over the full length of the heating element may result in inconsistent effectiveness and/or possible catheter damage • Place monitoring electrodes as far as possible from the Venclose™ catheter when the digiRF™ Generator and physiological monitoring equipment are used simultaneously on the same patient • Do not use needle monitoring electrodes • Use monitoring systems incorporating high frequency current-limiting devices • There is a risk of pooling of flammable solutions under the patient, or in body depressions such as the umbilicus, and in body cavities such as the vagina. These fluids should be mopped up before using the Venclose™ system • Endogenous gases (e.g., cotton and gauze saturated with oxygen) may be ignited by sparks produced within the generator during normal use of the Venclose™ system • The Venclose™ system is for use without a neutral electrode • The patient should not come into contact with grounded conductive components or conductive components with appreciable capacitance to earth, such as metallic operating table supports • Do not begin energy delivery (by pressing the catheter handle button or a connected foot switch) before the catheter is properly positioned within the intended treatment vessel and anesthesia is administered, or discomfort or injury may occur • Avoid contact of cords and cables with patient, lead, or other equipment.

Potential Adverse Events

Potential adverse events include, but are not limited to the following: vessel perforation • skin discoloration • nerve injury • temporary paresthesia • thrombosis • deep vein thrombosis • phlebitis • hematoma • infection • skin burn • pulmonary embolism • pain

Venclose Maven™ Perforator Catheter

Streamlining Venous Reflux Disease Treatment

Overview
Products & Accessories
EIFU & Resources

Simplified RF Ablation

For patients with Chronic Venous Disease (CVD), the Venclose Maven™ Perforator Catheter is used for treatment of incompetent perforator veins (IPVs) and tributary veins through endovenous radiofrequency (RF) ablation. RF ablation has been established as a CVD treatment option for more than 20 years.

In the U.S., an estimated 175 million Americans are affected by Chronic Venous Disease (CVD). Risk of CVD increases with age, but can begin as early as adolescence. Visible venous disease is far more than a cosmetic problem.^1-3Left untreated, CVD can progress to venous ulceration.

At 2.0 million, the annual number of new venous ulcer cases exceeds that of other chronic diseases including the 1.7 million new cases of all cancers combined and diabetic foot ulcers at 1.0 million new cases¹

A Modernized
360° Approach

The only 360° heating coil RF catheter solution for the treatment of incompetent perforator and tributary veins* that avoids the need for repeated quadrant ablations.**

The Venclose Maven™ Perforator Catheter is powered by the Venclose™ RF Ablation Generator - both are intended to be used together as a system.

Safety & Warnings

* As of March 2026

** The Venclose Maven™ Perforator Catheter uses 0.5 cm segmental ablation with a 20-second ablation cycle. The ClosureRFS™ Stylet uses pull back or focal ablation. Both ClosureRFS™ Stylet ablation methods require an initial quadrant ablation treatment time of 4 minutes. The pull back method requires additional quadrant ablation treatments for 1 minute per 1 cm, and the focal method requires additional quadrant ablation of subsequently treated adjacent vein segments for 4 minutes each. The ClosureRFS™ Stylet information was obtained from the manufacturer’s procedure guidelines.
