A device for reducing pulsatile pressure within a vessel to treat heart disease, such as pulmonary hypertension, includes a compliant body structured to expand and contract upon changes in pressure within the vessel, a reservoir structured for holding a fluid therein, and a conduit extending between and fluidly coupling the reservoir and the compliant body, wherein the device includes a graphene-polymer composite designed to resist diffusion of the fluid through the device. |
