Bone anchors for use in attaching soft tissue to a bone
First Claim
1. A bone anchor assembly for use in anchoring a plurality of sutures attached to soft tissue to a bone of a living organism, comprising:
- a bone anchor comprised of;
an anchor body extending between a proximal end and a distal end, said anchor body having an interior bore with an opening at said proximal end;
a first pin disposed within said bore and fixed to said anchor body, thereby providing a first interior attachment location for attaching a suture within said bore; and
a second pin in communication with said bore so as to be disposed transversely and distally relative to said first pin, thereby providing a second interior attachment location for attaching at least one additional suture within said bore; and
a plurality of looped sutures that pass through said bore and which have free ends that extend from said proximal opening,a first of said looped sutures being looped around said first pin,a second of said looped sutures being looped around said second pin, anda third of said looped sutures being looped around said second pin and being separated from said second of said looped sutures by said first pin.

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.

11. A bone screw assembly for use in anchoring a plurality of sutures attached to soft tissue to a bone of a living organism, comprising:
-
a bone screw comprised of; an anchor body extending between a proximal end and a distal end, said anchor body having an interior bore extending along a substantial length of said anchor body with a proximal opening at said proximal end; said anchor body having a threaded section comprising threads extending circumferentially about said threaded section of said anchor body and substantially at said proximal end; said anchor body having a non-threaded section extending between said threaded section and said distal end, wherein said non-threaded section is at least about 20% of the length of the threaded section; and at least one suture attachment structure in communication with said bore and fixed to said anchor body to provide one or more attachment locations for attaching a plurality of sutures thereto; and three looped sutures that pass through said interior bore, are attached to said at least one suture attachment structure, and have free ends that extend from said proximal opening. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. 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; an axial bore with an opening at said proximal end, at least a portion of the bore being shaped to form a socket for receiving a driver; at least one suture attachment structure in communication with said axial bore for engaging one or more sutures; a proximal threaded section that extends circumferentially to said proximal end; and a distal threaded section; wherein said proximal threaded section is multi-fluted so as to have more threads per unit length than said distal threaded section, the proximal and distal threaded sections each being positioned on the anchor body and having a length 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 during use. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A bone anchor assembly for use in anchoring a plurality of sutures attached to soft tissue to a bone of a living organism, comprising
a bone anchor comprised of: -
an anchor body extending between a proximal end and a distal end, said anchor body having an interior bore with an opening at said proximal end;
at least a portion of said bore being shaped to form a socket for receiving a driverat least one rigid suture attachment structure in communication with said bore for slidably attaching three sutures a proximal threaded section that extends circumferentially to said proximal end; and
a distal threaded section, wherein said proximal threaded section is multi-fluted so as to have more threads per unit length than said distal threaded section, the proximal and distal threaded sections each being positioned on the anchor body and having a length 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 during use; anda plurality of looped sutures that pass through said bore and have free ends that extend from said proximal opening, each of said sutures being slidably attached to the rigid suture attachment structure. - View Dependent Claims (28, 29)
