Suture anchors and assemblies for attaching soft tissue to bone
First Claim
1. A suture anchor assembly for attachment of tissue to bone, the suture anchor assembly comprising:
- an anchor body having a longitudinal axis, a distal end forming a fixed distal tip, a proximal end forming a proximal face transverse to the longitudinal axis, an interior bore opening at the proximal face, and threads beginning at a periphery of the proximal face and extending toward the distal end;
a socket formed in a proximal portion of the interior bore, opening at the proximal face, and being configured to receive a correspondingly shaped driver;
a rigid member fixedly and non-removably attached to the anchor body and in communication with the interior bore, wherein the rigid member is positioned transverse to the longitudinal axis of the anchor body at a location distal to the socket and fixed relative to the proximal face, the socket, and the distal tip; and
a tissue securing suture looped around the rigid member and having free ends for attachment to soft tissue, wherein the tissue securing suture extends outside the anchor body and exits through the socket at the proximal face of the anchor body.

Abstract
Improved bone anchors are disclosed for anchoring one or more sutures attached to soft tissue to a bone. The bone anchor has an anchor body that extends between a distal end and a proximal end. A bore is formed axially in the anchor body and opens at the proximal end. One or more pins are fixed within the bore of the anchor body. One or more sutures can be looped on the pins for anchoring soft tissue to bone. The anchor body has a socket within the bore for receiving a driver tool. The distal end of the anchor body forms a non-threaded extension, which stabilizes the bone anchor, and helps prevent lateral movement during use. In one embodiment, the anchor body has coarse threads for engaging soft bone tissue and fine threads for engaging hard bone tissue.

28. A suture anchor assembly for attachment of tissue to bone, the suture anchor assembly comprising:
-
an anchor body having a longitudinal axis, a distal end forming a fixed distal tip, a proximal end forming a proximal face transverse to the longitudinal axis, threads extending fully to a periphery of the proximal face, and an interior bore opening at the proximal face, a proximal portion of the interior bore forming a socket configured to receive a driver and being wider than a distal portion of the interior bore in order to prevent insertion of the driver into the distal portion; a rigid member fixedly and non-removably attached to the anchor body in communication with and positioned distal to the socket of the interior bore, wherein the rigid member provides a location that is fixed relative to the proximal face, the socket, and the distal tip for looped attachment of a tissue securing suture; and a driver having a size and shape so as to be positionable within the socket formed in the proximal portion of the interior bore without hitting the rigid member, the driver further including a hole through which the tissue securing suture, when attached to the anchor body, can be threaded. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
