Patent ID: 8311628

Claim:
An implantable lead that is configured for connection to an implantable medical device, the implantable lead comprising: a) an electrical conductor having a length extending from a proximal conductor end that is configured to be connectable to a medical device to a distal conductor end; b) a tank filter electrically connected in series with the electrical conductor somewhere along the length thereof, the tank filter comprising: i) a capacitor comprising at least one first electrode plate supported on a first ceramic substrate and at least one second electrode plate supported on a second ceramic substrate, wherein the first and second ceramic substrates are stacked one on top of the other so that the first and second electrode plates at least partially overlay each other in a spaced apart relationship and wherein the first and second electrode plates are electrically connected to spaced apart first and second metallization surfaces; and ii) an inductor comprising at least one inductor trace of electrically conductive material supported on a third ceramic substrate, wherein the third ceramic substrate is layered either on top or on the bottom of the stacked first and second substrates, but with the inductor trace spaced apart from the first and second electrode plates; and iii) wherein the first, second and third ceramic substrates are characterized as having been sintered together to form a monolithic body with the spaced apart ends of the inductor trace being electrically connected, to the respective first and second metallization surfaces to thereby electrically connect the capacitor in parallel with the inductor; and c) an electrode electrically connected to the electrical conductor at a position that is distal of the tank filter.
