Abstract

A method whereby an anchor member is configured to provide anchorage of its attached suture within a hole drilled in a bone.

Claims

1. A method for anchoring in bone a member and attached suture, comprising the steps of:

forming a hole in the bone;

attaching a suture to a member;

lodging the member within the hole by pressing the member with attached suture into the hole; and

attaching tissue to the suture so that the tissue is secured against the bone.

4. The method of claim 1 wherein the tissue is a non-bony tissue.

5. The method of claim 4 wherein the tissue is a member of the group consisting of cartilage, tendon, or ligament.

2. A method for anchoring in bone a member and attached suture, comprising the steps of:

forming a hole in the bone;

attaching a suture to a member;

lodging the member within the hole by pressing the member with attached suture into the hole; and

deforming the member in a manner such that the member resiles against the portion of the bone that defines the hole.

3. A method for anchoring in bone a member and attached suture, comprising the steps of:

forming a hole in the bone;

attaching a suture to a member by threading the suture through a passage in the member so that neither end of the suture is fastened to the member; and

lodging the member within the hole by pressing the member with attached suture into the hole.

6. A method of anchoring in bone a member and attached suture, comprising the steps of:

providing a deformable member having a width dimension "D";

attaching a suture to the member;

forming a hole in a bone in a manner such that the hole has a diameter that is not greater than the width dimension "D"; and

inserting the member into the hole with the member oriented such that the member lodges within the hole in the absence of any manipulation of the member other than inserting the member into the hole.

7. The method of claim 6 wherein the attaching step includes threading the suture through the member so that the suture defines two contiguous segments extending from the member.
