    摘要: The self-resonance insertion loss dip of a feedthrough capacitor is reduced or eliminated by raising the equivalent series resistance of the capacitor, thus minimizing the capacitor Q. The equivalent series resistance of the capacitor can be raised by forming voids in the active and/or ground electrode plates of the capacitor. The electrode plates may be formed so as to have a relatively reduced thickness, or a relatively increased thickness. A conductive material having a relatively high resistivity may be used to form the active and/or ground electrode plates of the capacitor. Alternatively, the conductive material forming the electrode plates may have a dielectric material added thereto.

    摘要: A TANK filter is provided for a lead wire of an active medical device (AMD). The TANK filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the TANK filter is resonant at a selected frequency. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the TANK filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the TANK filter is integrated into a TIP and/or RING electrode for an active implantable medical device.

    摘要: In an electromagnetic interference (EMI) filter terminal for an active implantable medical device (AIMD), an insulated and shielded RF telemetry pin is provided to prevent re-radiation of unwanted stray signals, including the telemetry signal itself, to adjacent sensitive circuits or lead wires. The invention provides for an EMI filter terminal assembly for an AIMD including a radio frequency (RF) telemetry pin antenna extending therethrough. The RF telemetry pin antenna includes a conductive shield extending over a portion of the RF telemetry pin antenna in non-conductive relation with the telemetry pin, and conductively connected to a ground associated with the AIMD. The assembly may also include an insulation tube between the RF telemetry pin antenna and the conductive shield covering a portion of the RF telemetry pin antenna.

    摘要: An EMI filter capacitor assembly utilizes biocompatible and non-migratable materials to adapt electronic components for direct body fluid exposure. The assembly includes a capacitor having first and second sets of electrode plates which are constructed of non-migratable biocompatible material. A conductive hermetic terminal of non-migratable and biocompatible material adjacent to the capacitor is conductively coupled to the second set of electrode plates. One or more conductive terminal pins having at least an outer surface of non-migratable and biocompatible material are conductively coupled to the first set of electrode plates, while extending through the hermetic terminal in non-conductive relation. The terminal pins may be in direct contact with the first set of electrode plates, or in contact with a termination surface of conductive connection material. The termination surface is also constructed of non-migratable and biocompatible materials. Layers of glass may be disposed over surfaces of the assembly, including the capacitor.
