Claim Text:
1. An implantable medical lead, comprising: a) an implantable lead wire; b) an electrode that is adapted to be placed in contact with biological cells; and c) a coil comprising multiple turns of conductive material, wherein the coil is in series with the lead wire and the electrode, d) wherein an inductance and a capacitance of the coil result in the coil having a self-resonance at a resonant frequency, and e) wherein the inductance and an inductor resistance provide a relatively low impedance from 10 Hz to 1 kHz such that the coil permits passage of biological signals having frequencies from 10 Hz to 1 kHz, and f) wherein a capacitance reactance and a capacitance resistance substantially act as an open circuit to the same biological signals having the frequencies from 10 Hz to 1 kHz that the inductance and inductor resistance permit to pass, and g) wherein the coil has relatively high impedance at the resonant frequency, and h) wherein the self-resonance has a Q having a 3 dB bandwidth that is on the order of MHz.
