Abstract
Abstract A suture having a surgical needle connectable to one end has an enlarged anchoring member secured to the other end thereof. A lateral projection is provided on the anchoring member. The lateral projection is grasped by a physical instrument to position the anchor member during the suture tying procedure and a slit formed in the anchor member releasably secures the suture to the anchor member for subsequent tensioning adjustments.
