Patent

CA 2656814

The present invention is directed to a device and method for safely removing matter collected by a matter collecting catheter from body organ or internal passage by means of a collecting sheath comprising an elongated tube having at a distal end thereof a deformable container sleeve, a main lumen passing therealong, said lumen being suitable for the passage of the matter collecting catheter through said elongated tube and said deformable container sleeve, and a secondary lumen passing along the walls of said elongated tube and said deformable container sleeve, wherein said secondary lumen terminates in a distal opening near a distal opening of said deformable container sleeve such that a distal end portion of a wire passed through said secondary lumen may be adapted to close said distal opening of said deformable container sleeve by proximal retraction of said wire.

La présente invention concerne un dispositif et un procédé permettant de retirer en toute sécurité de la matière prélevée sur un organe ou un passage corporel à l'aide d'un cathéter. Ce dispositif, qui se présente sous forme de gaine collectrice, comprend un tube allongé comportant, à son extrémité distale, un manchon récepteur déformable traversé d'une lumière principale par laquelle passe ledit cathéter à travers le tube allongé et le manchon récepteur et une seconde lumière passant le long des parois dudit tube allongé et dudit manchon récepteur déformable, débouchant sur une ouverture distale située à proximité d'une ouverture distale du manchon récepteur déformable. Un fil peut être introduit par son extrémité distale dans la seconde lumière et tiré en arrière pour fermer l'ouverture distale du manchon récepteur déformable.
