    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 for producing a biocompatible stent, a tubular substrate of the stent adapted for diametric expansion has a layer of a noble metal oxide formed over at least the outer surface of greater diameter of the substrate, the substrate being composed of a metal or an alloy thereof that is non-noble or less-noble than the layer's noble metal. An interface region adapted to prevent corrosion and to provide a firm bond between the surface of the substrate and the noble metal oxide layer is established, at least in part, by forming the noble metal oxide layer with a progressively varying concentration of noble metal-to-oxide with depth of the layer such that a surface of pure noble metal and negligible oxide of the layer is in closest proximity to the surface of the substrate. In one embodiment of the process, the interface region is established by forming the surface of pure noble metal and negligible oxide thereof in direct contact with the metal or alloy of the substrate surface. In another, the interface region is established by first creating an oxide of the substrate metal or alloy thereof at the substrate surface, and then forming the noble metal oxide layer as above, but in contact with the substrate metal or alloy oxide. Alternatively, the noble metal oxide layer has no progressively varying concentration but simply overlies an oxide of the substrate metal or alloy.

    Abstract: A medical device lead includes a thin profile conductor assembly. A proximal connector includes a proximal end that is configured to couple the lead to a pulse generator. An insulative lead body extends distally from the proximal connector. The conductor assembly extends distally from the proximal end within the lead body and includes a non-conductive tubular core member that defines a lumen, an outer insulative layer, and a multilayer conductor between the tubular core member and the outer insulative layer. The multilayer conductor is electrically connected to the proximal connector and includes a first conductive layer adjacent to the tubular core member and a second conductive layer adjacent to the first conductive layer opposite the tubular core member. A conductivity of the second conductive layer is greater than a conductivity of the first conductive layer.
