Suture anchor device, kit, and method

1. A method of anchoring tissue to bone using suture, the method comprising:

providing an anchor driver;

providing an anchor having a head portion with walls adapted to receive the 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 suture to the tissue;

threading the suture so it is entrained in the channel of the anchor;

placing the anchor against a bone, the bone having an outer surface;

inserting the anchor into the bone until the head portion is positioned about flush with the outer surface of 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 insertion of the anchor into the bone pulls a length of suture between the tissue and the anchor into the bone; and

removing the anchor driver once the head portion of the anchor is positioned about flush with the outer surface of the bone.

2. The method of claim 1 , wherein the shank has a longitudinal length, and the inserting step positions the anchor such that the head portion is less than ten percent of the shank's longitudinal length below the outer surface of the bone.

3. The method of claim 1 , wherein the inserting step is preceded by the step of coupling the anchor driver to the head of the anchor.

4. The method of claim 1 , wherein the outer walls of the shank of the anchor include walls tapering to a point and the channel includes at least a pair of openings on the outer walls of the shank.

5. The method of claim 4 , wherein the placing step includes the step of placing the point against a surface of the bone.

6. The method of claim 5 , wherein the inserting step includes urging the point into the bone until the channel openings of the anchor are below a surface of the bone.

7. The method of claim 1 , wherein the inserting step includes rotation of the anchor into the bone.

8. The method of claim 1 , further including the steps of providing a cannula; providing a suture passer; and wherein, prior to engaging step, the suture is threaded to the suture passer and transported through the cannula to the tissue.

9. The method of claim 1 , wherein the suture is engaged to the tissue prior to the threading step, and wherein the insertion of the anchor causes the tissue to move closer to the anchor.

10. A method of anchoring tissue to bone using suture, the method comprising:

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 suture to the tissue;

threading the 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 a bone, the bone having an outer surface;

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 insertion of the anchor into the bone pulls a length of suture between the tissue and the anchor into the bone;

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 the outer surface of the bone and the head portion is positioned about flush with the outer surface of the bone; and

removing the anchor driver once the head portion of the anchor is positioned about flush with the outer surface of the bone.

11. The method of claim 10 , wherein the insertion of the anchor includes rotation of the anchor into the bone.

12. The method of claim 11 , wherein the suture is engaged to the tissue prior to the threading step, and wherein the rotation of the anchor causes the tissue to move closer to the anchor.

13. The method of claim 10 , further including the steps of providing a cannula; providing a suture passer; and wherein, prior to engaging step, the suture is threaded to the suture passer and transported through the cannula to the tissue.

14. A method of anchoring tissue to bone using suture, the method comprising:

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 suture to the tissue;

threading the suture so it is entrained in the channel of the anchor;

placing the anchor against a bone, the bone having an outer surface;

inserting the anchor into the bone with the anchor driver 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 is positioned about flush with the outer bone surface, wherein the insertion of the anchor into the bone pulls a length of suture between the tissue and the anchor into the bone; and

removing the anchor driver once the head portion of the anchor is positioned about flush with the outer bone surface.

15. The method of claim 14 , wherein the anchor defines a pointed tip at a removed end thereof and wherein the inserting step includes the step of urging the pointed tip into the bone.

16. The method of claim 14 , further including the steps of providing a cannula; providing a suture passer; and wherein, prior to engaging step, the suture is threaded to the suture passer and transported through the cannula to the tissue.
