Claim 18:
19. 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 configured to anchor the implantable device to the tissue;

engaging a portion of the tissue using a forward longitudinal movement of the longitudinal movements of the push wire, the forward longitudinal movement resulting from pushing the push wire toward the conduit front end;
trapping the engaged portion of the tissue using a reverse longitudinal movement of the longitudinal movements of the push wire, the reverse longitudinal movement being a longitudinal movement in a direction opposite to a direction of the forward longitudinal movement: and
passing a fluid through a lumen to facilitate the engagement of the portion of the tissue, the lumen including at least one of the push wire lumen of the conduit of the implantable device or a core lumen of the push wire,
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.
