Method and apparatus for attaching connective tissues to bone using a knotless suture anchoring device
First Claim
1. A method for securing connective tissue to bone, comprising:
- a) creating a slit in a bone, which is open along its length at a surface of said bone and which extends along an anticipated suture path between said connective tissue and a hole in said bone for securing an anchoring device;
b) attaching suturing material to the connective tissue which is to be attached to the bone;
c) securing said suturing material to said anchoring device; and
d) inserting said anchoring device into said hole, so that the suturing material is disposed in said slit between said anchoring device and said connective tissue.

Abstract
An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.

11. A method for securing connective tissue to bone, comprising:
-
creating a first portal in said bone;
creating a second portal in said bone, having an orientation generally transverse to that of the first portal; and
inserting a suture anchoring device comprising a shaft having a lumen therein disposed along a length of the shaft, for receiving a length of suturing material therethrough, into said first portal.

12. A method for securing connective tissue to bone, comprising:
-
creating a first portal in said bone, for receiving a suture anchoring device; and
creating a second portal in said bone, having an orientation generally transverse to that of the first portal, for receiving suturing material which attaches said suture anchoring device to the connective tissue;
wherein said first portal comprises a bore generally parallel to and beneath said connective tissue, and the second portal communicates with the first portal and with said connective tissue, the second portal having a slot-type geometry.

19. A method for securing connective tissue to bone, comprising:
-
a) attaching a length of suturing material to the connective tissue which is to be attached to the bone by passing said suturing material through said connective tissue to form a suitable stitch;
b) securing said length of suturing material to an anchoring device;
c) inserting said anchoring device into said bone; and
d) tensioning said length of suturing material after said inserting step, in order to approximate said connective tissue to said bone, said tensioning step being performed without axially moving any portion of said anchoring device or members directly attached to said anchoring device and without tying any knots in said suturing material. - View Dependent Claims (20, 21, 22)
