Patent ID: 8649857

Claim:
An implantable medical therapeutic or diagnostic device, comprising: a) an electrode; b) a lead wire having a length extending from a distal portion connected to the electrode to a proximal end that is electrically connectable to an electronic circuitry of an active medical device, wherein the lead wire is at least partially coiled along its length to thereby provide a coiled wire portion forming a coil lumen; and c) a capacitor having a first metallization electrically connected to at least one first electrode plate interleaved with a second, opposite polarity electrode plate electrically connected to a second metallization, wherein the coiled wire portion wraps around the capacitor disposed in the coil lumen with the first capacitor metallization connected to the coiled wire portion at a first electrical connection spaced from the second capacitor metallization connected to the coiled wire portion at a second electrical connection to thereby form a tank filter having electrical inductance in parallel with capacitance; d) wherein the tank filter attenuates current flow over a range of selected frequencies.
