Abstract
An improved monolithic multilayer ceramic filter capacitor for use with implanted medical devices such as pacemakers and defibrillators. The capacitor includes a parallel stack of positive electrode plates that have sufficient current carrying capability to be directly connected in series with a lead wire from an implanted medical device. Therefore, the capacitor may be used for both filtering and pulsed energy transmission. High current capability is achieved through the use of interleaved electrode plates where the positive electrodes are connected in parallel, and where at least one of the positive electrodes is of sufficiently high conductor density to carry a majority of the current transmitted by the implantable medical device lead.
