An apparatus for sealing a puncture in a body vessel has a sealing member (10) comprising a flexible tubing (11) having an internal passageway (14). The tubing (11) is provided at an open distal end (15) thereof with an elastic expansion member (16) for self-expanding said open distal end (15) to an expanded configuration; and a pursing member (20) which is arranged to purse said flexible tubing (11). A method for sealing a puncture in a body vessel, comprises introducing a distal end of the sealing member through the puncture; allowing the elastic expansion member to self-expand to an expanded configuration in the vessel, detecting a blood flow through the internal passageway as an indication of the distal end of the sealing member being positioned inside the body vessel, and thereafter sealing the internal passageway by pursing the flexible tubing outside the body vessel.
L'invention concerne un dispositif pour l'obturation de vaisseau corporel perforé, qui comporte un élément d'obturation (10) doté d'un tube flexible (11) à passage interne (14). Le tube (11) présente en une extrémité distale ouverte (15) un extenseur élastique (16) qui dilate ladite extrémité (15); et un élément de boursage (20) pour le boursage du tube flexible (11). L'invention concerne également un procédé correspondant, qui comprend les étapes suivantes: introduction de l'extrémité distale susmentionnée dans la perforation; extension de l'extenseur dans le vaisseau traité, détection d'un flux sanguin dans le passage interne prouvant que l'extrémité distale est placée dans le vaisseau, et obturation du passage interne par boursage du tube flexible à l'extérieur du vaisseau.
