A method and an apparatus for anchoring a medical implant device within a blood vessel or other body passageway are described herein. An anchor delivery system houses one or more expandable anchors connected to the medical implant device. The anchors remain housed in a non-expanded configuration until the medical implant device has been placed in a desired position within the body, and then the anchors are propelled through a body wall where each anchor expands outwardly from an anchor shaft. In one configuration, each anchor is formed as a compressible closed loop which extends outwardly from an anchor shaft and loops back to cross over and extend beyond the anchor shaft. To propel the anchors, a drive shaft is connected to a triggering unit which, when activated, causes the drive shaft to drive the anchor shafts in a direction such that the anchors are propelled through the body wall.
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
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; andfurther 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. 2. The method of claim 1, wherein extending the tip of the anchor through the opening comprises extending the tip laterally through the opening. 3. The method of claim 1, wherein the central anchor portion comprises a shape-memory material, and wherein extending the anchor such that the central anchor portion is curved to form a closed loop comprises returning the central anchor portion to a pre-shaped form. 4. The method of claim 1, wherein extending the anchor beyond the second surface such that the central anchor portion is curved to form a closed loop comprises curving the central anchor portion arcuately toward the second surface such that the tip of the anchor extends away from the second surface. 5. The method of claim 1, wherein, when the central anchor portion compresses the second surface, the body wall is caught between the closed loop and the hollow leg. 6. A method of anchoring a medical device within a body, comprising: positioning a hollow leg of the medical device against a first surface of a body wall;advancing an anchor from within the hollow leg through an opening in a wall of the hollow leg proximal to a distal most end of the hollow leg;passing a distal most portion of the anchor completely through the body wall, wherein the distal most portion of the anchor that has passed completely through the body wall crosses over itself; andcompressing an exterior surface of the body wall with the anchor that has passed completely through the body wall, wherein the compression increases as a force is applied to the anchor in a proximal direction.
