  • Publication number: 20060229671
    Abstract: A sterile suture anchor comprising a body with a distal end, tapered planar side walls and a dome shaped proximal end, a cross section of said body forming a triangular shape with at least one rounded end; and a suture aperture transversely cut through the body being dimensioned to hold at least one suture. An insertion tool for inserting the suture anchor through a substantially cylindrical bore hole in a live human bone and causing the suture anchor to be anchored comprises a handle, a hollow tube secured to the handle and a driver rod slidably mounted in the tube. The driver rod has a distal end defining an angled cam which engages a suture anchor mounted in said tube and rotates the suture anchor into a desired position for insertion into human tissue.
