摘要： 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.

摘要： An implantable device for reducing pulsatile pressure within a blood vessel is described herein, for example to treat pulmonary hypertension. The implantable device may include a fluid reservoir, a compliant member (e.g., a balloon), and a conduit coupled to the fluid reservoir and the compliant member. Advanced designs for anchoring the compliant member in the blood vessel are described. In addition, enhanced reservoir, conduit, and balloon designs, as well as methods for implanting/using the same, are provided.
