Abstract

An apparatus and method for manipulating and anchoring tissue is provided. The invention is directed to solving the problem of manipulating and anchoring tissue within a joint when access to that tissue is limited, for example, during arthroscopic surgery.

Claims

1. An apparatus for insertion into and through tissue to provide a mechanism for manipulating and anchoring tissue within a patient, the apparatus comprising:

an elongated anchor member having opposite ends that are tapered to be insertable into and through the tissue to be manipulated, the member being shaped to normally assume a substantially straight configuration; and

a suture irremovably attached to the anchor member between the opposite ends of the anchor member, the suture having an end free for manipulating the tissue into which the anchor member is inserted, the suture being flaccid in the vicinity of the anchor member so that the suture and anchor member do not assume a predetermined relative orientation.

2. The apparatus of claim 1 wherein the suture is a flexible, non-stiffened member in the vicinity of the anchor member.

3. The apparatus of claim 1 wherein the anchor member is resiliently deformable.

4. The apparatus of claim 1 wherein the tapered ends of the anchor member define slanted end faces.

5. The apparatus of claim 1 wherein the suture is attached to facilitate substantially perpendicular extension of the suture from the anchor member.

6. The apparatus of claim 1 wherein the suture is attached to the anchor member medially thereof and extends laterally away from said elongated anchor member.

7. The apparatus of claim 1 wherein the anchor member is insertable through the tissue to be manipulated by the suture to a position underneath the tissue and the suture extends therefrom to outside of the tissue.

8. The apparatus of claim 1 wherein the suture and anchor member are configured such that the end of the suture is free for manipulating the anchor member to thereby manipulate the tissue.

9. The apparatus of claim 1 wherein the free end of the suture is a first end and the suture also has a second end, which second end is fixed to the anchor member, and wherein the anchor member is insertable to a manipulation position underneath the tissue that is thereafter to be manipulated, and wherein in the manipulation position, the first end is outside the tissue and the second end is underneath the tissue.

10. The apparatus of claim 1 wherein the suture and anchor member have a manipulation position in which the anchor member is substantially entirely underneath the tissue to be manipulated.

11. The apparatus of claim 1 wherein the anchor member is attached to the suture near the longitudinal midpoint of the anchor member and the suture extends laterally therefrom.
