  • Patent number: 5259846
    Abstract: A loop threaded needle-suture device is disclosed wherein a surgical needle is provided with a pointed end and a drilled aperture extending axially of the butt end, and a length of flexible suture material is doubled upon itself to form a loop, both free ends of which are attached to the needle in the butt end aperture. The blunt end of the needle is deformed to form the aperture into an elliptical cross-section and the length of the loop is substantially greater than the length of the needle to facilitate insertion of the needle and suture material into tissue to be sutured, and looping the needle through the suture material prior to tieing the suture material. Thus, the loop functions as a double suture. A method of forming the unique loop threaded needle-suture is disclosed.
