Abstract:
1. An implantable medical device (AIMD), comprising: a) a hermetically sealed and thermally or electrically conductive AIMD housing containing tissue-stimulating or biological-sensing circuits for the AIMD; b) a hermetic feedthrough terminal supported by the AIMD housing, wherein the feedthrough comprises c) a single or multi-pole double throw switch residing inside the AIMD housing and being electrically couplable in series with and uncouplable from the at least one first leadwire of the first conductive path, the switch comprising a first throw end, a second throw end, and a switch pole end, wherein the switch pole end is permanently electrically coupled to the tissue-stimulating or biological-sensing circuits, and the first throw end is at and electrically connected to the proximal first leadwire end; and d) a second conductive path permanently electrically coupled between the second throw end of the switch and the conductive AIMD housing; and e) wherein the switch is configured to be selectively actuatable in response to a programmable telemetry signal to either electrically connect the switch pole end to the first throw end or connect the switch pole end to the second throw end.
