Abstract
Diffusion and infusion resistant implantable devices and methods for reducing pulsatile pressure are provided. The implantable device includes a balloon implantable within a blood vessel of a patient, e.g., the pulmonary artery. The balloon is injected with a fluid mixture comprising a constituent fluid(s) and a diffusion-resistant gas to provide optimal balloon volume and limit fluid diffusion throughout multiple cardiac cycles. The fluid mixture may be pressurized such that the balloon is transitionable between an expanded state and a collapsed state responsive to pressure fluctuations in the blood vessel.
