Abstract:
1. An ionizing radiation-protected active implantable medical device (AIMD), comprising: a) an AIMD housing; b) an electronics package including a microprocessor disposed within the AIMD housing, wherein the electronics package has a first external surface area and a remainder external surface area, which first and remainder external surface areas together add up to a total external surface area of the electronics package; c) a battery disposed within the AIMD housing, the battery being adapted to provide electrical power to the electronics package including the microprocessor, wherein the battery directly faces the first external surface area of the electronics package to thereby shield the first external surface area from ionizing radiation; and d) a gold shield disposed within the AIMD housing, wherein the gold shield is positioned between the AIMD housing and the remainder external surface area of the electronics package, but not between the battery and the AIMD housing to thereby provide an attenuation of ionizing radiation of at least 0.5 HVL at the remainder external surface area of the electronics package so that the battery together with the gold shield shields the total external surface area of the electronics package.
