Abstract

An implantable medical device is provided including a housing, an external circuit element extending outwardly from the housing, an internal circuit enclosed by the housing, a feedthrough array disposed along the housing having at least one filtered feedthrough and at least one unfiltered feedthrough, wherein the unfiltered feedthrough is adapted for connection to the outwardly extending circuit element; and including means for minimizing electromagnetic coupling between the filtered feedthrough and the unfiltered feedthrough.
