ABSTRACT OF THE DISCLOSURE A needle-suture combination is provided in which the suture has at its tip within a recess at the blunt end of the needle and extending to a segment adjacent the attach- ment of the suture to the needle, a cross-sectional area and a cross-sectional amount of suture material less than the cross-sectional area and the cross-sectional amount of suture material in the remainder of its length. In one embodiment, the invention provides a weakened segment which permits a surgeon to separate the needle from the suture by a sharp tug. In another embodiment the invention also permits the use of needles having substantially the same external diameter as the suture attached thereto so that the suture in the sewn tissue substantially plugs the needle hole.
