Bone anchors for use in attaching soft tissue to a bone
First Claim
1. A bone anchor for use in anchoring one or more sutures attached to soft tissue to a bone of a living organism, comprising an anchor body extending between a proximal end and a distal end, said anchor body having an interior bore that opens at said proximal end;
- and a first pin disposed within said bore and fixed to said anchor body, thereby providing an interior attachment location for attaching a suture.

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 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.

17. A bone anchor for use in anchoring one or more sutures attached to soft tissue to a bone having hard bone tissue and soft bone tissue, the bone anchor comprising:
an anchor body extending between a proximal end and a distal end, said anchor body further comprising;
a proximal threaded section;
a distal threaded section; and
wherein said proximal threaded section includes threads that are finer than threads of said distal threaded section such that said proximal threaded section is configured to engage hard bone tissue and said distal threaded section is configured to engage soft bone tissue. - View Dependent Claims (18, 19, 20, 21, 22, 24, 25)
