Abstract
Abstract A needle-suture combination with reduced diameter portion of the suture being attached to the blunt end of the needle. The maximum diameter of the suture being almost the same but no larger than the diameter of the blunt end of the needle and the reduced diameter portion of the suture having a tensile strength greater than the remainder of the suture.
