Abstract
Abstract A surgical suture device comprising a backer in the form of a streamlined bead fixedly connected to opposing ligature strands, the free ends of the ligature strands being connected to surgical needles; the streamlining of the backer eliminating excess surfaces and corners which tend to promote the formation of blood clots, and the fixed relationship between the backer and the ligature strands preventing twisting of the backer and tangling of the ligature strands.
