1. A method for introducing fluids into an implantable system, the method comprising:
implanting a balloon within a blood vessel of a patient;
determining an amount of a diffusion-resistant fluid to introduce into the balloon and introducing the amount of the diffusion-resistant fluid into the balloon;
determining an amount of one or more constituent fluids to introduce into the balloon and introducing the amount of the one or more constituent fluids into the balloon;
permitting the one or more constituent fluids to equilibrate across the balloon such that each of the one or more constituent fluids is pressurized within the balloon to match their respective partial pressure in the blood surrounding the balloon within the blood vessel; and
after a predetermined time period, determining a current volume of fluids within the balloon and either extracting fluids from the balloon or introducing an additional amount of the diffusion-resistant fluid into the balloon to achieve a desired active volume of fluids within the balloon.
