Suture anchors and assemblies for attaching soft tissue to bone
First Claim
1. A suture anchor for attachment of tissue to bone, comprising:
- an anchor body having a longitudinal axis, a proximal end forming a proximal face transverse to the longitudinal axis, a distal end, and an interior surface which defines an interior bore that opens at the proximal face and extends distally from the proximal end along the longitudinal axis, the interior bore having a proximal bore portion and a distal bore portion;
at least one thread beginning at a periphery of the proximal face and extending distally toward the distal end to form a threaded portion of the anchor body, the threaded portion including a proximal threaded half and a distal threaded half;
a socket formed in the proximal bore portion and opening at the proximal face for receiving a correspondingly shaped driver; and
a rigid member fixedly attached to the anchor body within the distal bore portion and distal to the socket, wherein the rigid member is transverse to the longitudinal axis and includes a proximal surface and a distal surface, wherein the rigid member, including the proximal surface and the distal surface, are fixedly positioned in a region of the anchor body containing the distal threaded half so as to provide a fixed location within the distal bore portion and in the region containing the distal threaded half for attachment of a suture loop.

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.
