SUTURE ANCHOR
First Claim
1. A sterile suture anchor comprising:
- a cylindrical body portion with a generally tapered distal end portion, a screw thread extending along said cylindrical body portion, a plurality of longitudinal grooves cut into said cylindrical body interrupting opposed portions of said screw thread;
a suture cavity transversely cut through said distal end portion engaging said plurality of longitudinal grooves, said suture cavity being dimensioned to hold at least one suture; and
a suture pathway means formed in said distal end portion communicating with said suture cavity allowing a suture to be inserted via said suture pathway means into said cavity.

Abstract
A suture anchor comprising a cylindrical body portion with in inwardly tapered distal end portion has a screw thread extending along the cylindrical body portion and a plurality of parallel longitudinal grooves cut into the cylindrical body interrupting opposed portions of the screw thread. A suture cavity is transversely cut through the distal end portion and engages the plurality of longitudinal grooves, the suture cavity being dimensioned to hold at least one suture. The distal end portion defines a suture pathway comprising two separated leg members, each of which has an inner angled end surface leading into the suture cavity providing an entry passageway for a suture into the suture cavity and a driver for the suture anchor.

28. A sterile suture anchor for insertion into bone comprising:
-
an anchor body constructed of cortical bone, said bone anchor body having a driver end and a lead-in end, said bone anchor body having a threaded surface formed by broken threads with said threaded surface having a plurality of suture grooves extending longitudinally along said anchor body and cut into said bone anchor body at a depth to hold a suture;
said suture grooves extending into a suture cavity formed transverse to a longitudinal axis of the bone anchor body and extending through said bone anchor body, and a suture loading slot extending from said lead-in end into said suture cavity.
