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. |
