Suture anchor with insert-molded suture eyelet

摘要

An insert-molded suture anchor with a biodegradable polymer body in which a loop of suture is totally contained within the polymer. The suture anchor body features a drive end that is shaped to be received into a recess in the end of a hand driver. Anchoring ribs are formed along the remaining length of the anchor. The loop of suture which includes and eyelet for attaching a suture strand is totally embedded within the anchor body during the insert-molding fabrication process. The anchor is produced by placing the suture in an injection mold, and injecting biodegradable polymer into the mold.

主权项

1. An insert-molded suture anchor, comprising:
a ribbed body formed of a biodegradable polymer, the ribbed body having a longitudinal axis, a proximal end and a distal end, the ribbed anchor body being provided with a plurality of adjacent, truncated cones and terminating at its distal end in a truncated cone with a blunt tip; an eyelet formed in a drive end provided at the proximal end of the anchor, the eyelet being formed as an opening through the drive end, the drive end being configured to be received in a driver head of a driver, so that the drive end of the anchor is received in a recess in a cannula of the driver head; and a suture completely insert molded within the anchor, the suture including an insert-molded portion in the form of a loop disposed around the eyelet at the drive end of the suture anchor body, the loop being totally contained within the polymer of the body.
