Abstract

An apparatus for implanting an implant device having a corkscrew-type anchor associated therewith into a patient includes an elongated, flexible shaft. A retention mechanism is located at the distal end of the shaft for retaining the device at the distal end of the shaft. The apparatus includes means selectively operable for disengaging the retention mechanism from the implant device when the anchor has been anchored into tissue at a target site. In another aspect, an apparatus for releasing an implant into a vessel within a patient includes an elongated shaft for inserting into the vessel of the patient. A tether wire extends through the proximal portion of a secondary lumen, exits a first port, engages a portion of the implant, enters a second port, and extends through at least a portion of a distal portion of the secondary lumen. The implant is thereby tethered to the side of the elongated shaft, and pulling the tether wire disengages the tether wire from the distal portion of the secondary lumen and the implant so as to release the implant from the shaft.
