Abstract:
1. A method, comprising: positioning a distal end of a catheter proximate a body structure; providing a piercing member containing a plurality of tissue anchors, each tissue anchor comprising a tubular element having a longitudinal passage defining an inner surface extending along an entire longitudinal length of the tissue anchor, each tissue anchor forming an eyelet; providing a purse string that passes entirely through the longitudinal passage and entirely along the inner surface of each of the tissue anchors when the tissue anchors are within the piercing member; securing the tissue anchors to tissue of the body structure comprising advancing the piercing member into a wall of the body structure by passing the piercing member through an inner surface of the wall of the body structure, deploying at least one of the tissue anchors from said piercing member such that at least a portion of the tissue anchor on each side of the eyelet contacts the outer surface of the wall of the body structure and the eyelet is generally perpendicular to the remainder of the tubular element when deployed and the purse string passes through the eyelet and is capable of applying a force to each of the tissue anchors once deployed; and applying force to the purse string to draw at least some of said tissue anchors towards each other.
