US Patent 10201353 Ligation clip

The ligation clip includes opposing legs connected at a connection point at which the clip pivots to the clamped position on a vessel. The entire clip has a completely semi-circular outside surface. The inside vessel engaging surfaces of the legs of the clip have a unique vessel retaining system that includes a plurality of rounded protrusions alternating with rounded depressions. The retaining system is positioned “within” the inside vessel engaging surfaces of the legs such that a flat surface remains adjacent to our around the retaining system. In addition, there are no sharp edges associated with the ligation clip. All transition points between the outer and inner surfaces of the clip are rounded to prevent any sharp edges.
