Power management for an implantable medical device
First Claim
1. A power management system for an implantable medical device comprising in combination:
- (a) an implantable power source delivering energy to at least two components within the implantable medical device;
(b) a measurement device to measure the energy of the power source; and
(c) a processor responsive to the measurement device and capable of limiting energy to only a recharge module if the energy of the power source falls below a predetermined critical level.

Abstract
A power management system and technique to manage and allocate the energy provided to various components of an implanted device during periods of low energy. The power management system includes an implantable power source delivering energy to various components within the implantable medical device, a measurement device to measure the energy of the power source, and a processor responsive to the measurement device. The processor monitors the energy level of the power source. During periods of low energy, the processor limits the energy to certain device-critical components of the implantable medical device. This minimizes the risk of damage to the power source resulting from high energy drain during periods of low energy. Further, this preserves operation of device-critical components of the implanted device during periods of low energy.
