Venous catheter Panlvin®

3 FR4 FR

Product Introduction
Panlvin® BHKY infusion catheter is designed for endovascular mechanochemical ablation (MOCA) of lower‑limb varicose veins. The system enables non‑thermal, tumescent‑free procedures in an outpatient/day‑surgery setting and is fully disposable. Clinical multicenter data report a 93.67% occlusion rate versus traditional thermal ablation, with low incidence of venous thrombosis and avoidance of thermal, skin and nerve injury.

Features

• Non‑thermal MOCA: reduces risk of nerve injury and skin burns compared with thermal techniques.
• Fast procedure: typically completed in ~20 minutes without tumescent anesthesia.
• Improved patient comfort: reduces pain during and after treatment.
• Minimally invasive access: 3‑Fr catheter compatible with a 4‑Fr sheath.
• Outpatient workflow: suitable for day‑surgery and ambulatory care with rapid recovery.
• Disposable system: no capital equipment required, simplifying procurement and reducing upfront costs.

Principle
Under image guidance (ultrasound or DSA), the catheter lumen is placed into the target vein and the guidewire inside the catheter is rotated by a motorized handle. Mechanical friction of the rotating guidewire tip on the endothelium induces venous spasm, collagen/matrix degeneration and endothelial injury. Simultaneous infusion of a sclerosing agent through the catheter increases endothelial contact and penetration. The combined mechanical and chemical action produces vein fibrosis and vessel closure leading to occlusion.
