ABSTRACT:
A delimited portion of suture material is immersed into a freezing media, such as liquid nitrogen, until the delimited portion is frozen. The frozen delimited portion is cut to provide a stiffened, non-brooming suture tip suitable for insertion into a needle bore. The cut, frozen suture tip is inserted into a needle and the needle is crimped to attach the suture to the needle. After attachment, the frozen suture tip returns to ambient temperature, reversing the effects of freezing the suture portion so that the suture adjacent the needle is as flexible as the remainder of the suture.
