Suture anchor with insert-molded rigid member

摘要

A threaded suture anchor with an eyelet shield transversely molded at a distal end of the anchor body, over which one or more strands of suture is looped. The anchor body is threaded and has a tapered distal portion. The proximal end portion of the suture anchor body has a polygonally shaped opening to accept a polygonal drive head, preferably hexagonal or square. The peripheral surface defining polygonally shaped opening is rounded and smooth to prevent abrading sutures placed in contact therewith. In another embodiment, a push-in anchor is provided with an eyelet shield at the proximal end of the anchor.

主权项

1. A suture anchor comprising:
an anchor body having a longitudinal axis, a proximal end, a distal end, a central passage, a first suture opening, and a second suture opening, wherein the central passage extends along the longitudinal axis, the central passage extends from the first suture opening which is located at the proximal end of the anchor body and through a portion of a length of the anchor body, the first suture opening is encircled by a perimeter of the anchor body, and the second suture opening extends through a portion of the anchor body; a rigid support fixed to the anchor body, wherein the rigid support extends across the central passage and has a first portion and a second portion spaced from the first portion, the first portion branching from a first wall portion of the anchor body and the second portion branching from a second wall portion of the anchor body, the rigid support spaced axially away from the first suture opening along the longitudinal axis of the anchor body, and the second suture opening is disposed near the rigid support; and at least one suture strand threaded into the central passage, wherein the at least one suture strand is supported by the rigid support and threaded through the first suture opening and the second suture opening of the anchor body.
