Apparatus and methods for positioning and securing anchors
First Claim
1. An anchor for implantation in a body, comprising:
- an anchor body adapted to be placed against a tissue surface and having a flexible member pass at least partially therethrough; and
a bridging member having at least one collar extending therefrom such that the collar defines an opening for passage of the flexible member, wherein the bridging member is configurable from a delivery profile within a hollow member to a locking profile outside the hollow member.

Abstract
Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism either within the anchor itself of positioned proximally of the anchor may allow for the uni-directional translation while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This uni-directional anchor locking mechanism facilitates the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.

18. A method for cinching an anchor relative to tissue, comprising:
-
ejecting an anchor body in proximity to the tissue;
urging the anchor body distally along a flexible member into contact against a surface of the tissue to be cinched; and
inhibiting the anchor body from moving proximally along the flexible member via a bridging member having at least one collar extending therefrom, wherein the collar is positioned proximally of the anchor body with the flexible member passing therethrough, and wherein the bridging member is configurable from a delivery profile within a hollow member to a locking profile outside the hollow member. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
