ABSTRACT:
A method for forming a surgical clip and fixture for use therein includes molding a polymeric clip body, the clip body having hinged legs, the polymer of the clip body being substantially amorphous. The clip body can then be moved to a desired configuration while being subjected to a temperature above the glass transition temperature. The molded clip body is then heated to a temperature within the crystallization range for a period of time sufficient to impart at least 20% crystallinity thereto to impart a spring back property. Also disclosed herein is a fixture for forming a surgical clip in accordance with this method.
