CA 2614492

An intravascular cuff acts as a lining between a native vessel and an intravascular prosthetic device. During deployment, the ends of the cuff curl back upon themselves and are capable of trapping native tissue, such as valve leaflet tissue, between the ends. The cuff creates a seal between the vessel and the prosthetic, thereby preventing leakage around the prosthetic. The cuff also traps any embolic material dislodged from the vessel during expansion of the prosthetic.

La présente invention concerne un manchon intravasculaire qui agit comme un recouvrement entre un vaisseau natif et un dispositif prothétique intravasculaire. Durant le déploiement, les extrémités du manchon se recourbent vers l'arrière sur elles-mêmes et sont capables de piéger un tissu natif, tel qu'un tissu de valvule, entre les extrémités. Le manchon crée une étanchéité entre de vaisseaux et la prothèse, empêchant une fuite autour de cette prothèse. Ce manchon piège aussi toute matière embolique délogée du vaisseau pendant l'expansion de la prothèse.
