The V-Block Occlusion Stent and Sclerotherapy Device for Varicose Vein Treatment: A Retrospective Analysis.

Background: The procedure aims to show our results with a novel nontumescent, nonthermal technique to treat varicose veins. The V-block occlusion stent is a minimally invasive device for treating reflux of the great saphenous vein (GSV). It is an office-based procedure that does not require tumescence anesthesia.

The evaluation of a novel technique to treat saphenous vein incompetence: preclinical animal study to examine safety and efficacy of a new vein occlusion device.

Objectives: We tested a novel technique to treat great saphenous vein (GSV) incompetence in an animal model.

Methods: V-block (VVT Medical Ltd, Kfar Saba, Israel), an occlusion device composed of a nitinol frame and anchoring hooks, was percutaneously deployed at the saphenofemoral junction in 12 sheep. Four of the 12 sheep were treated with adjunctive liquid sclerotherapy.
