Claim 15:
16. A method for coapting a body lumen in tissue of a living body, the method comprising:
providing an implantable device including
an adjustable membrane element including a continuous wall having an inner surface defining a chamber;
an elongate conduit including a conduit peripheral surface, a conduit rear end, a conduit front end, and a push wire lumen, the conduit peripheral surface connected to and sealed to the adjustable membrane element at or near the conduit front end, the push wire lumen extending longitudinally in the conduit and having an inlet to receive a portion of a push wire and a diameter suitable for accommodating the received portion of the push wire; and
a fixation mechanism including pincers and configured to anchor the implantable device to the tissue;

engaging a portion of the tissue by opening the pincers using a forward longitudinal movement of the push wire resulting from pushing the push wire toward the conduit front end; and
trapping the engaged portion of the tissue by closing the pincers using a reverse longitudinal movement of the push wire resulting from pulling the push wire in a direction opposite to a direction of the forward longitudinal movement,
wherein the implantable device is configured for implantation within the tissue with the adjustable membrane element adjacent the body lumen to provide volume to the tissue for adjustable coaptation to the body lumen.
