1. A system for delivering an anchor assembly for applying retractive pressure to tissue, comprising:
- a distal anchor, wherein the distal anchor includes a head portion that is connected to a generally perpendicularly oriented tail portion via a connecting mid-section portion;
a suture, wherein the suture is attachable and tensioned to the distal anchor; and
a coiled proximal anchor for securing the suture as part of a proximal end of the anchor assembly, the coiled proximal anchor including a body, a portion of which includes coils with varying pitch.

19. 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. - View Dependent Claims (20, 21, 22, 23, 24)
