A method and device for sealing an opening in an anatomical structure within a living body involves the positioning of the tissue adjacent to the opening within a gap formed by a central part of a flexible tube between proximal and distal parts thereof. A movable surface coupled to the central part is also provided so that, in a first configuration, the movable surface is substantially continuous with outer surfaces of the proximal and distal parts and, in a second configuration, the movable surface projects away from the outer surfaces of the proximal and distal parts. A first needle coupled to a suture loop is drawn from a needle retention channel formed within the distal part through the tissue received in the gap and into a needle receiving channel formed within the proximal part. After the device has been rotated to a second position, the procedure is repeated and a second needle attached to the suture loop is drawn through the tissue in the same manner. The two ends are knotted together and tightened to seal the opening in the anatomical structure.

[ What is claimed is:] [1.] A device for sealing a hole in an anatomical structure within a living body comprising:a flexible tube including proximal and distal parts coupled together by a central part, the proximal part including an end portion which, when the device is in an operative position, is located outside the body;a movable surface coupled to the central part so that, in a first configuration, the movable surface is substantially continuous with outer surfaces of the proximal and distal parts wherein, in a second configuration, the movable surface projects away from the outer surfaces of the proximal and distal parts a predetermined distance;at least one needle retention channel formed within the distal part for holding a plurality of needles therein, wherein the needle retention channel extends to a distal part opening formed in the proximal end of the distal part;a needle receiving channel formed within the proximal part and extending to a proximal part opening formed in the distal end of the proximal part, wherein, at least in the second configuration, the distal part opening faces the proximal part opening across a gap formed by the central part between the proximal and distal parts; anda flash-back lumen extending from a proximal end opening formed in the end portion of the proximal part to one of an opening formed in the central part and the at least one needle retention channel.
