Bone anchors for use in attaching soft tissue to bone
First Claim
Patent Images
1. A bone anchor for use in anchoring one or more tissue securing sutures to a bone of a living organism, comprising:
- an anchor body having a longitudinal axis and extending between a proximal end forming a proximal face transverse to said longitudinal axis and a distal end forming a fixed distal tip, said anchor body further comprising;
a longitudinal bore having a proximal opening at said proximal face;
a socket formed in a proximal portion of said longitudinal bore through said proximal opening and configured to receive a correspondingly-shaped driver tool; and
threads on an exterior surface of said anchor body beginning at a periphery of said proximal face and extending toward said distal end;
a transverse pin, fixedly and non-removably attached to said anchor body, disposed within and extending across said longitudinal bore at a location distal to said proximal face and fixed relative to said proximal face and said distal tip; and
a tissue securing suture looped around said transverse pin and having free ends extending from said proximal opening of said longitudinal bore.

Abstract
Bone anchors for attaching soft tissue to bone include an anchor body having a bore that opens at a proximal end and a suture attachment site in communication with the bore for slidably receiving a suture thereon. In one embodiment, three suture attachment sites are provided by two transverse pins placed within the bore. The bone anchors can be fully threaded and, in one embodiment, can have fine and coarse threads for engaging cortical and cancellous bone tissue, respectively.

22. A bone anchor for use in anchoring one or more tissue securing sutures to a bone of a living organism, comprising:
-
an anchor body extending along a longitudinal axis between a proximal end forming a proximal face transverse to said longitudinal axis and a distal end forming a fixed distal tip, said anchor body further comprising; a longitudinal bore having a proximal opening at said proximal face; a socket formed in a proximal portion of said longitudinal bore through said proximal opening and being configured to receive a correspondingly-shaped driver tool; threads having a single continuous pitch beginning at a periphery of said proximal face and extending from said proximal face toward said distal end; and a fixed, non-removable rigid member, configured for looped attachment of at least one tissue securing suture thereto, in communication with said longitudinal bore and positioned transverse to said longitudinal axis at a location distal to said proximal face and fixed relative to said proximal face and said distal tip; and a tissue securing suture looped around said fixed, non-removable rigid member and having free ends extending from said proximal opening of said longitudinal bore. - View Dependent Claims (23, 24, 25, 26)

27. A bone anchor for attachment of tissue to bone, the bone anchor comprising:
an anchor body including a longitudinal axis, a distal end forming a fixed distal tip, and a proximal end forming a proximal face transverse to said longitudinal axis, said anchor body further comprising; threads beginning at a periphery of said proximal face, extending toward said distal end, and providing a major diameter of said anchor body; a longitudinal bore extending from a proximal opening at said proximal face through said anchor body toward said distal end; a socket formed in a proximal portion of said longitudinal bore through said proximal opening and being configured to receive a correspondingly-shaped driver tool; and a fixed, non-removable rigid member, configured for looped attachment of at least one tissue securing suture thereto, in communication with said longitudinal bore and at a location fixed relative to said proximal face and said distal tip; and a tissue securing suture looped around said fixed, non-removable rigid member and including a first end and a second end, wherein said first end and said second end of said tissue securing suture extend out of said proximal opening at said proximal end of said anchor body. - View Dependent Claims (28, 29, 30)
