Implantable medical device with a dual power source
First Claim
Patent Images
1. A method for incorporating a power source in an implantable medical device, comprising the steps of:
- independently providing power to a control circuit by a first power source positioned within the device, the control circuit obtaining physiological data of a patient in which at least the control circuit is implanted;
independently providing power to a communication circuit by a second power source positioned within the device; and
sensing a remaining power level of the second power source, the first power source, or both first and second power sources to determine if the remaining power level of either the first or second power source has fallen below a predetermined threshold; and
providing power to the control circuit and the communication circuit by a) the first power source if the remaining power level of the second power source has fallen below a predetermined threshold or b) the second power source if the remaining power level of the first rower source has fallen below a predetermined threshold.

Abstract
An implantable medical device includes a control circuit for controlling the operation of the device and for obtaining physiological data from a patient in which the medical device is implanted. The implanted device also includes a communication circuit for transmitting the physiological data to an external device. A first power source is coupled to the control circuit and provides power to the control circuit. A second power source is coupled to the communication circuit and provides power to the communication circuit.
