Abstract
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.
Claims21
A system for reducing pulsatile pressure, the system comprising:
- a reservoir configured to hold a fluid therein;
- a transvascular conduit having a proximal region and a distal region, the proximal region coupled to the reservoir;
- and
- a compliant body configured to be implanted in a vessel and coupled to the distal region of the transvascular conduit, the compliant body further configured to contract during systole to move the fluid towards the reservoir and to expand during diastole to thereby reduce peak pressure in the vessel, wherein the compliant body is formed from a carbon-polymer composite configured to resist diffusion of the fluid through the compliant body.
