Knotless bioabsorbable suture anchor system and method
First Claim
1. A system for anchoring tissue to bone, comprising:
- a suture anchor having proximal and distal ends, wherein a suture-engaging tip is present at the distal end of the anchor and a separate, radially expandable sleeve, having a bore formed longitudinally therein, is attached to the suture-engaging tip and forms a proximal end of the suture anchor;
a first loop of suture thread attached to the suture-engaging tip;
a second loop of suture thread interlocked with the first loop of suture thread; and
a suture needle having a first, tissue penetrating end and a second, trailing end, wherein the suture needle is attached to the second loop of suture thread.

Abstract
A knotless suture system for anchoring tissue to bone is provided. The system includes a suture anchor configured to radially expand into bone. The suture anchor has a proximal end and a distal end with a bore formed therein. The system further includes a first loop of suture thread attached to the distal end of the suture anchor, a suture needle, and a second loop of suture thread attached to the needle and interlocked with the first loop of suture thread. The system also includes an expander pin that is configured and sized for insertion into the bore of the suture anchor, causing the anchor to radially expand from a first outer diameter to a second outer diameter. A method is also provided by which a detached tissue may be securely attached to bone in an anatomically correct position without the need to tie a knot.

20. A system for anchoring tissue to bone, comprising:
-
an expandable base member having a distal end and a proximal end, the proximal end having a bore extending longitudinally therein and at least part of the proximal end being selectively radially expandable;
a first loop of suture thread attached to the base member;
a second loop of suture thread interlocked with the first loop of suture thread;
a suture needle having a first, tissue penetrating end and a second, trailing end, wherein the suture needle is attached to the second loop of suture thread; and
an expander pin, selectively disposable within the bore of the base member to radially expand the base member from a first outer diameter to a second outer diameter. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A suture anchor, comprising:
-
a first component including a tip having a suture thread-engaging groove formed therein, and a through-hole extending through the tip in a direction transverse to a longitudinal axis of the suture anchor;
a second component having an external surface with at least one positive surface feature formed thereon, at least a portion of the second component being selectively radially expandable; and
a bore extending into the second component of the suture anchor from the proximal end thereof, the bore being parallel with the longitudinal axis of the suture anchor. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
