Vascular closure

摘要

Clip apparatus for closing a vessel aperture resulting from insertion of a surgical implement comprising an elongated strand comprising a central portion and extremity portions extending from said central portion. The tips of said extremity portions remote from said central portion are shaped to retain tissue encountered thereby. The extremity portions have memory characteristics seeking to cause said extremity portions to curl with respect to said central portions to retain tissue engaged thereby when said strand is in an unconstrained disposition.
