Suture anchor device, kit and method
First Claim
1. A method of anchoring tissue to bone using suture comprising the steps of:
- providing an anchor driver;
providing an anchor having 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;
placing the anchor against the bone; and
inserting the anchor into the bone such that the suture lies wedged between and substantially contacting 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.

11. A method of anchoring tissue to bone using suture comprising the steps of:
-
providing an anchor having 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; engaging the anchor driver with the head of the anchor; placing the anchor against the bone; and inserting the anchor into the bone such that the suture lies wedged between and substantially contacting the bone and the walls of the anchor in an interference fit; wherein the outer walls of the shank of the anchor includes walls tapering to a point and the channel includes at least a pair of openings on the outer wall of the shank; wherein the placing step includes the step of placing the point of the anchor against a surface of the bone; and wherein the inserting step includes urging the point into the bone until the channel openings are below a surface of the bone. - View Dependent Claims (13, 14)

15. A method of anchoring tissue to bone using suture comprising the steps of:
-
providing an anchor comprising a head portion at a near end thereof 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, the shank including a pointed tip;engaging the suture to the tissue; threading suture so it is entrained in the channel of the anchor; placing the anchor against the bone; 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, the inserting step continuing until the anchor head and at least a portion of the suture is at or below the bone surface. - View Dependent Claims (16, 17)
