1. An apparatus for improving compliance of a pulmonary artery, the apparatus comprising:
- a subcutaneously implantable reservoir configured to hold a fluid;
a conduit having first and second implantable ends, the first implantable end configured to be coupled to the subcutaneously implantable reservoir to provide fluidic communication between the subcutaneously implantable reservoir and the conduit;
a compliant body configured to be fully implantable, the compliant body coupled to the second implantable end of the conduit to provide fluidic communication between the compliant body and the conduit, the compliant body sized and shaped to be implanted in the pulmonary artery;
a fluid disposed in the subcutaneously implantable reservoir, conduit, and compliant body, the fluid pressurized so that the compliant body transitions between an expanded state, caused by diastolic pressure in the pulmonary artery, and a contracted state, caused by systolic pressure in the pulmonary artery; and
a fully implantable anchoring system configured to anchor the compliant body within the pulmonary artery, the anchoring system comprising wire that engages an inner wall of the pulmonary artery and remains anchored, allowing the complaint body to be periodically removed and replaced.

Abstract
A device for reducing pressure within a lumen includes a reservoir structured for holding a fluid therein, an injection port in fluid communication with the reservoir, a compliant body structured to expand and contract upon changes in pressure, and a conduit extending between and fluidly coupling the reservoir and the compliant body. The fluid may be a compressible or a noncompressible fluid.
