CA 2397746

A multiple-sided medical device (10) comprises a frame (11) comprising wire or other resilient material and having a series of bends (12) and interconnecting sides. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs (16) for anchoring purposes. A full or partial covering (45) of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame to form an occlusion device (51), a stent graft (75), or an implantable, intraluminal valve (43) such as for correcting incompetent veins in the lower legs and feet.

L'invention concerne un dispositif (10) médical à plusieurs côtés comprenant un cadre (11), constitué d'un fil ou autre matériau élastique, qui comporte une série d'incurvations (12) et de côtés de liaison. Ledit dispositif est poussé, par un cathéter d'implantation, dans la lumière d'un conduit ou d'un vaisseau. Ledit dispositif peut comporter un ou plusieurs ardillons (16) destinés à son ancrage. Une enveloppe (45) totale ou partielle, en tissu ou autre matériau flexible tel que le DACRON, le PTFE ou fabriquée dans un matériau à base de collagène tel que les sous-muqueuses de l'intestin grêle (SIS), peut être cousue ou fixée sur ledit cadre de manière à former un dispositif (51) d'occlusion, une greffe d'extenseur (75) ou une valvule (43) intracavitaire implantable, telle que celles qui permettent de corriger des veines inopérantes de la partie inférieure des jambes et des pieds.
