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.

Apparatus for improving compliance of a pulmonary artery for treatment of pulmonary hypertension, the apparatus comprising:
- a subcutaneous reservoir;
- a conduit having a distal end and a proximal end coupled to the subcutaneous reservoir, the conduit configured to extend through the subclavian vein such that the distal end is implanted distal to a pulmonary valve;
- a compliant body coupled to the distal end of the conduit, the compliant body configured for placement in the pulmonary artery distal to the pulmonary valve;
- and
- a fluid disposed in the subcutaneous reservoir, the conduit, and the compliant body,
- wherein the compliant body further is configured to contract during systole to move the fluid towards the subcutaneous reservoir and to expand during diastole, the expansion and contraction configured to decrease peak pressure in the pulmonary artery and improve compliance of the pulmonary artery, thereby reducing remodeling of the pulmonary artery.
A method for improving compliance of a pulmonary artery for treatment of pulmonary hypertension, the method comprising:
- implanting a compliant body in the pulmonary artery distal to a pulmonary valve, a reservoir subcutaneously, and a conduit coupled to the compliant body and the reservoir such that the conduit extends through the subclavian vein;
- contracting the compliant body during systole to move a fluid from the compliant body towards the reservoir through the conduit;
- and
- expanding the compliant body during diastole to move the fluid from the reservoir towards the compliant body through the conduit,
- wherein the contracting and the expanding are configured to decrease peak pressure in the pulmonary artery and improve compliance of the pulmonary artery, thereby reducing remodeling of the pulmonary artery.
