Abstract

A coiled anchor that secures to a connector as part of an anchor assembly is disclosed. The coiled anchor includes windings which capture and deform the connector between the windings and prevent the connector from disengaging from the coiled anchor once engaged.

Claims

1. A method for tissue manipulation involving at least one anchor assembly, the method comprising:

deploying an implantable distal anchor and an attached suture at a first site;

deploying a coiled proximal anchor at a second site spaced from the first site, the coiled proximal anchor including coils with a varying pitch; and

turning the coiled proximal anchor onto the suture;

wherein the coiled proximal anchor lockingly engages and deforms the suture.

2. The method of claim 1, further comprising assembling the coiled proximal anchor.

3. The method of claim 2, wherein the coiled proximal anchor includes two separated and unattached coil sections.

4. The method of claim 2, wherein assembling involves inserting a plug into the coiled proximal anchor.

5. The method of claim 2, wherein assembling involves configuring first and second coil sections on an H-shaped substructure.

6. The method of claim 2, further comprising longitudinally contracting the coiled proximal anchor to fix the coiled proximal anchor to the suture.
