Abstract: Systems and methods for a resonator with an adjustable capacitance for a medical device. In one embodiment, a resonator system includes a resonator device with an LC resonator circuit that has an adjustable capacitance, an inductor coil in series with the adjustable capacitance, and an adjustable capacitance control that can control the adjustable capacitance to obtain different particular capacitance values. This embodiment also includes a medical device, positioned with the resonator device, so that at least a portion of the inductor coil surrounds a space that is surrounded by at least a portion of the medical device.

Abstract: In a process of fabricating a stent composed primarily of niobium alloyed with a trace amount of zirconium, tantalum, or titanium for hardening, the stent is annealed under vacuum in a substantially oxygen-free environment. The vacuum is preferably maintained at pressure less than 10−4 millibars, oxygen-content less than about 80 parts per million, and the annealing temperature exceeds 400° C. for at least one hour, and is preferably kept in a range from about 1100-1200° C. for several hours. This may be followed by applying a surface layer of oxide, such as iridium oxide, with a thickness of 299-300 nm to the stent.
