1. A method for deploying a medical device in a body, wherein the medical device includes an elongate hollow leg having an opening proximal to a distal end of the hollow leg, an elongate anchor shaft disposed within the hollow elongate leg, and an anchor at a distal end of the anchor shaft having a tip at a distal end of the anchor and a central anchor portion adjacent to the tip, the method comprising:

  • extending the tip of the anchor through the opening of the hollow leg such that the tip of the anchor completely penetrates a body wall from a first surface of the body wall to a position beyond a second surface of the body wall; and

    further extending the anchor beyond the second surface such that the central anchor portion is curved to form a closed loop and compress the second surface,wherein, in response to a force applied to the anchor in a proximal direction, a radius of curvature of the closed loop decreases such that the closed loop decreases in diameter.
