<p>A method and device (1) 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 between proximal and distal parts (18,24) of a flexible tube (16) formed by a curved central part (22). A needle (37) coupled to a suture loop (41) is drawn from a needle retention channel (32) formed within the distal part (24) through the tissue received in the gap and into a needle receiving channel formed within the proximal part (18). The needle (37) may be drawn out by pulling on either the suture loop (41) or a separate pull cord (43) which extends through a lumen to an opening formed in the first end of the proximal part (18). After the device (1) has been rotated and the procedure repeated, a second needle (37) attached to the suture loop (41) is drawn through the tissue in the same manner and the two ends are knotted together and tightened to seal the opening. <IMAGE></p> |
