ClosureFast™ RFA Catheter CF7-7-100: Innovative Solution for Thermal Vein Closure

The ClosureFast™ RFA Catheter CF7-7-100 by Medtronic is a sophisticated medical device designed for thermal vein closure using radiofrequency energy. This catheter is part of the ClosureFast™ RFA system, known for its ability to deliver consistent and uniform heat to target veins, resulting in successful vein closure and symptom relief. The procedure is minimally invasive and performed on an outpatient basis, offering a modern alternative to traditional vein treatments.

The ClosureFast™ procedure uses radiofrequency energy to precisely heat and close the affected veins. This technique redirects blood flow to healthier veins, alleviating symptoms associated with venous insufficiency. The uniform heat application provided by the catheter ensures complete and effective closure of diseased veins.

Compared to conventional vein treatments, the ClosureFast™ catheter offers several advantages. It is associated with less pain and bruising than laser treatments, and the minimally invasive nature of the procedure results in a faster recovery time. Patients are required to wear compression stockings for at least one week after the procedure to support healing.

A key feature of the ClosureFast™ system is its patented segmental procedure, which ensures gap-free thermal ablation. The device's heating elements provide an overlap of 0.5 cm at each segment. This overlap eliminates gaps between treatment segments, leading to more effective and durable vein closure.

The ClosureFast™ CF7-7-100 catheter precisely heats a 7 cm segment of the vein in a single 20-second interval. The radiofrequency energy causes the target vein to shrink and collapse, creating a fibrotic seal that occludes the vessel. This process is crucial for achieving successful and lasting vein closure.

The ClosureFast™ CF7-7-100 catheter is provided sterile and is intended for single use only. Due to its design, the catheter cannot be adequately cleaned or sterilized for reuse, which helps prevent risks such as bio-incompatibility or infection. Each catheter is designed to ensure optimal performance and patient safety during the procedure.

The ClosureFast™ catheter is compatible with the ClosureRFG™ generator and the ClosureRFS™ stylet. The generator delivers the necessary radiofrequency energy to the catheter and stylet and features a controlled feedback mechanism to monitor and regulate intravascular heat parameters in real time.

After the procedure, patients are required to wear compression stockings to support vein closure and reduce swelling. The effective treatment of the ClosureFast™ system and minimal post-procedure discomfort contribute to a smooth recovery experience for patients.

The ClosureFast™ RFA Catheter CF7-7-100 by Medtronic represents a significant advancement in the treatment of diseased veins through radiofrequency thermal ablation technology. Designed to provide effective and durable vein closure, this device minimizes pain and bruising while promoting a rapid recovery compared to traditional laser treatments. Its robust construction and ability to deliver uniform heat ensure reliable and lasting results, while its single-use nature guarantees maximum patient safety.
