Abstract:
1. An implantable medical device (IMD) comprising: a housing configured for implantation in the body of a patient; operational circuitry having low power monitoring sub-circuitry elements and high power stimulus generating sub-circuitry elements; a power supply circuit coupled to the operational circuitry, the power supply circuit including at least first and second batteries and a plurality of switches, the power supply circuit configured to allow selective opening and closing of the switches such that the following output configurations are available: a first configuration in which the first and second batteries are coupled in series to provide a low power output from only the first battery and a high power output from the first and second batteries in series; and a second configuration in which the two batteries are isolated from one another to provide a low power output from only the first battery and a high power output from only the second battery; wherein the operational circuitry is configured to perform the following method:
