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 between proximal and distal parts of a flexible tube formed by a curved central part. A 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. The needle may be drawn out by pulling on either the suture loop or a separate pull cord which extends through a lumen to an opening formed in the first end of the proximal part. After the device has been rotated and the procedure repeated, a second needle attached to the suture loop is drawn through the tissue in the same manner and the two ends are knotted together and tightened to seal the opening.

[ What is claimed is:] [1.] A surgical stitching device comprising:a flexible tube including substantially linear proximal and distal parts defining an axis and a curved central part coupling the proximal and distal parts so that a gap is formed therebetween;a puncture needle channel extending through the proximal part along the axis to an opening formed in the distal end of the proximal part;a puncture needle receiving channel extending through the distal part along the axis to a suture retention channel, wherein the cross-sectional area of the suture retention channel is greater than the cross-sectional area of the puncture needle receiving channel;a puncture needle including a central lumen, the puncture needle being slidably received in the puncture needle channel so that, by applying pressure to a proximal end of the puncture needle, a user may manually move the puncture needle out of the opening formed in the distal end of the puncture needle channel, across the gap a nd into the puncture needle retention channel so that a distal end of the puncture needle is received within the suture retention chamber; anda piston slidably received in the central lumen so that, when the distal end of the puncture needle is received within the suture retention chamber, a user may move the piston distally through the central lumen.
