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.
