Abstract
A method is provided for anchoring a suture to a needle in which a suture tip is inserted into a recess in the blunt end of a needle and the needle is thereafter heated to expand the suture tip within the recess into tight engagement with the recess walls. Sutures of synthetic polymers attached in this manner are removable from the needle by application of a straight pulling force of less than about 30 ounces.
