Abstract

A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. An implant for attachment of soft tissue to bone, an insertion tool for anchoring suture anchors to bone, and a method for anchoring a suture anchor to bone.

Claims

1. A method of anchoring a suture in tissue, comprising:

providing a suture connected to a suture anchor, the suture anchor comprising a inserting portion, a positioning portion, and a body portion, wherein the body portion has a first configuration and a second configuration;

penetrating tissue in a penetrating direction with the inserting portion; and

tensioning the suture wherein the tensioning induces the positioning portion to orient the suture anchor transverse to the penetrating direction and wherein the tensioning induces the body portion to telescope outwardly to increase the effective volume of the suture anchor.

2. The method of claim 1 wherein the tensioning induces the body portion to pivot to increase the effective volume of the suture anchor.

3. The method of claim 1 where the tensioning induces the body portion to expand in a direction transverse to a longitudinal axis of the suture anchor to increase the cross-sectional area of the suture anchor.

4. A method of anchoring a suture in tissue, comprising:

providing a suture connected to a suture anchor, the suture anchor comprising a inserting portion, a positioning portion, and a body portion, wherein the body portion has a first configuration and a second configuration;

penetrating tissue in a penetrating direction with the inserting portion; and

tensioning the suture wherein the tensioning induces the positioning portion to orient the suture anchor transverse to the penetrating direction and wherein the tensioning induces the body portion to separate from a configuration of nested segments to a configuration of separated segments to increase the effective volume of the suture anchor.
