The present invention provides a medical device retrieval system comprising a working element carried by a flexible, elongate shaft, the working element having a proximal profile and the shaft extending proximally from the working element and a retrieval cover slidably carried along the shaft of the medical device, the cover having a deployed configuration and being capable of being compressed into a compressed configuration for deployment, yet resiliently substantially return to the deployed configuration; the cover in its deployed configuration having a radially reduced proximal portion, a distally open distal end defining a distal opening having a maximum dimension at least as great as the maximum dimension of the proximal profile of the working element of the medical device, and an elongate internal recess defined between the proximal portion and the distal end.
La présente invention concerne un système de retrait d'un dispositif médical comprenant un élément actif disposé sur une tige souple allongée, l'élément actif présentant un profil proximal et la tige s'étendant dans une direction proximale par rapport à l'élément actif ; et un couvercle de retrait disposé coulissant le long de la tige du dispositif médical, le couvercle présentant une configuration déployée et étant capable de subir une compression avant son déploiement et de retrouver de façon sensiblement élastique sa configuration déployée. Dans sa configuration déployée, le couvercle possède une partie proximale à réduction radiale, une extrémité distale à ouverture distale définissant une ouverture distale dont la dimension maximale est au moins aussi grande que la dimension maximale du profil proximal de l'élément actif du dispositif médical, et un creux intérieur allongé étant défini entre la partie proximale et l'extrémité distale.
