ABSTRACT:
Apparatus for connecting the ends of a suture stitch includes a piston and cylinder combination with one end of the suture secured to the cylinder. The other end of the suture initially includes a needle for penetrating two tissues to be approximated and then passing the needle and its attached suture through aligned openings in the cylinder sidewalls. The portion of the suture passing through the cylinder is trapped therein by the depression of the piston to engage the bottom inside surface of the cylinder which locks that end of the suture in place.
