Patent ID: 7416554

Claim:
Apparatus for securing a tissue fold within a patient, the apparatus comprising: an elongate member having a proximal end and a distal end; application apparatus extending from the distal end of said elongate member and having a distal portion adapted to engage a tissue fold within a patient; and an anchor assembly having proximal and distal anchors connected by a suture, said suture having a proximal end and a distal end, wherein the anchor assembly is adapted for adjustment of the length of suture disposed between the proximal and distal anchors while the anchor assembly is disposed across the tissue fold; further comprising an anchor delivery system adapted to deploy and secure the anchor assembly across the tissue fold; wherein the anchor delivery system comprises a flexible delivery tube having a lumen, and a hollow needle disposed within the lumen, said anchor delivery system having a distal region extending from the distal end of said elongate member; wherein the distal anchor passes through the hollow needle during delivery; wherein the anchor delivery system further comprises an anchor tube coupled to a distal region of the flexible delivery tube, and wherein the proximal anchor is disposed within the anchor tube during delivery; wherein the anchor delivery system further comprises a trap mechanism located substantially within the distal region of said anchor delivery system, said trap mechanism being adapted to reversibly trap the suture at or near its proximal end to facilitate adjustment of the length of suture disposed between the proximal and distal anchors, and wherein the trap mechanism is adapted to release the suture after the length of suture has been adjusted.
