  • a) molding a polymeric clip body, said molded clip body comprising a pair of legs and a hinge region to which one end of each leg is joined, said molded clip body being substantially amorphous; and

    b) treating said molded clip body at a temperature within the crystallization range, wherein said legs are in a predetermined rest position, said treating at said temperature within the crystallization range being maintained for a period of time sufficient to impart at least 20% crystallinity thereto to impart a spring back property to said hinge region, said spring back property being sufficient to bias said legs toward said rest position in response to deflection of said legs from said rest position to a deflected position.
