Suture anchor device, kit and method
First Claim
1. A method of anchoring tissue to bone using suture comprising, in the recited order, the steps of:
- providing an anchor comprising a head portion with walls adapted to receive an anchor driver; and
, a shank portion with outer walls, the shank with a channel therein, the channel connecting openings in the outer walls of the shank;
engaging the suture to the tissue;
threading suture so it is entrained in the channel of the anchor; and
inserting the anchor into the bone such that the suture lies wedged between and substantially contacting and directly engaging the bone and the walls of the anchor in an interference fit.

Abstract
A suture anchor and kit for anchoring a suture member to human bone in an interference fit. A suture anchor includes a threaded portion and has a head at the proximal end thereof, the head being generally circular. A tip is located at a distal end of the shank. The shank is at least partially threaded and includes walls defining a reel portion. The shank also includes walls for engaging a suture, the walls for engaging the suture typically adjacent walls defining the reel portion. The head typically includes walls for engaging a drive tool. The kit includes a drive tool for rotating the suture anchor when a suture member is engaged with the walls for engaging the suture such that rotation of the anchor causes the suture material to wrap around the reel portion of the shank.

7. A method of anchoring tissue adjacent bone, the method comprising, in the recited order, the steps of:
-
providing an anchor with outer walls having a ridge thereon; threading a tissue with a suture; engaging the suture to the anchor; selecting a site on a bone for anchor insertion; positioning the tissue with the suture attached adjacent the selected site; and driving the anchor into the hole so the suture is wedged between the walls of the hole and the anchor in an interference fit directly engaging the bone and anchor; wherein said driving step includes rotation of the anchor such that the suture winds around the anchor. - View Dependent Claims (8, 9, 10, 11, 12, 14, 16, 18)

13. A method for using a suture anchor having a suture receiving portion, the method comprising, in the recited order, the steps of:
-
(a) passing a suture member through tissue; (b) engaging the suture member with the suture anchor; and (c) driving the suture anchor longitudinally into the bone such that the suture member assumes an interference fit directly engaging both the suture and the bone;
wherein said inserting step includes rotation of the anchor such that the suture winds around the anchor.

19. A method of anchoring tissue to bone using suture comprising, in the recited order, the steps of:
-
providing an anchor comprising a head portion with walls adapted to receive an anchor driver; and
, a shank portion with outer walls, the shank with a channel therein, the channel connecting openings in the outer walls of the shank;engaging the suture to the tissue; threading suture so it is entrained in the channel of the anchor; and inserting the anchor into the bone such that the suture lies wedged between the bone and the walls of the anchor in an interference fit so the suture directly engages both the bone and walls of the anchor; wherein the inserting step moves the anchor longitudinally into the bone while simultaneously positioning the tissue adjacent the bone, the inserting step continuing until the anchor is at or below the bone surface.
