Vessel compliance restoration using dual inflatable sleeves

A compliance restoration implant device comprising:

• a first compliant fluid container having a first lumen that widens in response to fluid leaving the first compliant fluid container and narrows in response to the fluid entering the first compliant fluid container;
• a second compliant fluid container having a second lumen that widens in response to the fluid leaving the second compliant fluid container and narrows in response to the fluid entering the second compliant fluid container;
• a first port structure on an outer wall of the first compliant fluid container to provide fluid access to an interior of the first compliant fluid container;
• and
• a second port structure on an outer wall of the second compliant fluid container to provide fluid access to an interior of the second compliant fluid container.

A compliance restoration implant device comprising:

• a first compliant fluid container sized to be disposed within a vena cava vessel and having a first lumen to allow flow of blood therethrough away from a heart;
• a second compliant fluid container in fluid communication with the first compliant fluid container and sized to be disposed within an aorta, the second compliant fluid container having a second lumen to allow flow of blood therethrough to the heart;
• and
• a conduit structure extending between the first and second compliant fluid containers to provide the fluid communication between the first and second compliant fluid containers, the first and second compliant fluid containers alternating between a respective expanded state and a respective contracted state as fluid is passed between the first and second compliant fluid containers through the conduit structure.
