Abstract
A suture is attached to a surgical needle possessing a shank of reduced diameter the butt end of which is rounded. Attachment is accomplished by means of a shrinkable tubing which is fitted about the shank of the needle and an end of the suture, application of heat to the tubing effecting its shrinkage with consequent secure attachment of the needle to the suture. Rounding of the butt end of the needle shank minimizes the possibility that during use, the needle will protrude or rip through the tubing or otherwise compromise the security of the attachment of the needle to the suture.
