Suture loop anchor
First Claim
Patent Images
1. A suture anchor system for anchoring tissue to bone, comprising:
- a substantially solid, elongate body having proximal and distal ends with a longitudinal axis extending therebetween, the body including at least one longitudinally extending bone-engaging surface feature formed thereon;
a continuous suture-receiving channel extending distally from opposed sides of the proximal end of the body around the distal end of the body, the suture-receiving channel being adapted to seat a suture therein;
a first loop of suture thread freely-slidably disposed around the elongate body within the at least one suture-receiving channel, the suture loop including a proximal portion that is positioned proximal to the proximal end of the body.

Abstract
A suture anchor is provided having a body with at least one suture-receiving channel that extends distally from a proximal end of the body. The suture-receiving channel can include a cavity formed in a distal-most end of the body, or it can terminate at a transversely-extending bore formed through the body. The suture anchor can also include a suture loop that is positioned within the suture-receiving channel and cavity or bore, and that includes a proximal portion that extends proximal of the proximal end of the body.

12. A suture anchor adapted to be disposed within bone, comprising:
-
an elongate body having a proximal end, a distal end, and at least one discrete bone-engaging surface feature formed thereon and adapted to engage bone;
a transversely-extending suture tunnel formed proximal to the distal end of the body such that the distal end of the body has a substantially solid distal tip;
first and second opposed suture-receiving channels formed in the body and extending from the proximal end of the body and terminating at the suture tunnel; and
a suture loop disposed within the first and second opposed suture-receiving channels and the transversely-extending suture tunnel, the suture loop including a proximal portion positioned proximal of the proximal end of the body. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method for anchoring suture in bone, comprising:
-
providing a suture anchor having a generally elongate body with proximal and distal ends, a suture-receiving member formed on at least a portion of the body, and a suture loop extending around at least a portion of the body and positioned in the suture-receiving member such that a proximal portion of the suture loop is positioned proximal of the proximal end of the elongate body;
providing an operative suture;
forming a bone cavity within a bony structure;
passing the operative suture through the proximal portion of the suture loop; and
implanting the suture anchor in the bone cavity such that the operative suture extends from the cavity and is freely slidable with respect to the suture loop. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
