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.

Described herein are methods for the bromine-facilitated synthesis of fluoro-sulfur compounds, that include SF.sub.4, SF.sub.5Cl, SF.sub.5Br and SF.sub.6. The methods described herein generally require lower temperature and pressure, produce higher yields, require less time, do not use corrosive or costly reactants and solvents that are commonly used in the synthesis of the fluoro-sulfur compounds, and do not produce deleterious waste products when compared to previously-used methods.

A plant and a related method for the regeneration of fluorinated compounds, particularly sulfur hexafluoride, includes an inlet section designed to receive a gas mixture with the fluorinated compound to be regenerated, an outlet section designed to convey out the regenerated gas, and a fluid dynamic circuit that connects the inlet section to the outlet section and includes filtering elements. The filtering elements have a separation unit where the gas mixture is brought to a temperature and pressure that cause the fluorinated compound to condense while keeping the other components of the mixture in the gaseous state. The condensed fluorinated compound represents the regenerated compound to be conveyed toward the outlet section.
