CA 2346164

A guidewire capture sheath (50) for capturing a guidewire being progressed along the lumen of a body duct, wherein a capture means (52) is housed in, connected to or integral with a catheter (51), capable of moving between a first, retracted condition and a second, expanded condition, when the sheath is adapted to capture guidewire being progressed through the body duct from the other direction, and to direct it into the catheter (51). The guidewire capture sheath (50) is used during placement of vascular grafts, particularly trouser grafts, across an aneurysm.

Cette invention se rapporte à une gaine de capture de fil-guide (50), qui sert à capturer un fil-guide progressant à l'intérieur d'un conduit corporel. A cet effet, un moyen de capture (52) est soit logé dans un cathéter (51) soit relié à ce cathéter soit partie intégrante de ce cathéter, lequel peut se déplacer entre une première position repliée et une seconde position déployée, lorsque la gaine s'apprête à capturer un fil-guide progressant dans le conduit corporel en provenance de l'autre direction et à le diriger dans le cathéter (51). Cette gaine de capture de fil-guide (50) sert à placer des greffes vasculaires, notamment des greffes de type pantalon, pour contourner un anévrisme.
