Claim 10:
11. An implantable device kit for controllable coaptation of a body lumen in tissue of a living body, comprising:
a hollow core push wire including a push wire front end, a push wire rear end, and a core lumen extending longitudinally in the push wire and having one or more front openings at the push wire front end and a rear opening at the push wire rear end; and
an implantable device configured to be positioned in the tissue adjacent to the body lumen using the push wire and to control the coaptation of the body lumen, the 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 the push wire and a diameter suitable for accommodating the received portion of the push wire; and
a fixation mechanism coupled to the conduit front end and configured to anchor the implantable device to a portion of the tissue to limit displacement of the implantable device in the tissue after the positioning by engaging a portion of the tissue using a forward longitudinal movement of the push wire and trapping the engaged portion of the tissue using a reverse longitudinal movement of the push wire, the forward longitudinal movement resulting from pushing the push wire toward the conduit front end, the reverse longitudinal movement being a longitudinal movement in a direction opposite to a direction of the forward longitudinal movement, and the one or more front openings of the core lumen of the push wire are positioned for facilitating the engagement of the portion of the tissue by drawing a fluid from the core lumen,

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.
