Battery recharge management for implantable medical device

摘要

An implantable medical device having an implantable power source such as a rechargeable lithium ion battery. The implantable medical device includes a recharge module that regulates the recharging process of the implantable power source using closed-loop feedback control. The recharge module includes a recharge regulator, a recharge measurement device monitoring at least one recharge parameter, and a recharge regulation control unit for regulating the recharge energy delivered to the power source in response to the recharge measurement device. The recharge module adjusts the energy provided to the power source to ensure that the power source is being recharged under safe levels.

主权项

1. A recharge management system for an implantable medical device, comprising in combination:
a rechargeable power source operatively coupled with the implantable medical device; a recharge coil operatively coupled with the implantable medical device and being capable of receiving energy from an external device to recharge the rechargeable power source; a recharge measurement device configured to monitor a temperature; and a recharge regulation control unit configured to regulate a charging rate of the rechargeable power source by increasing the charging rate, at least in part, in response to the temperature monitored by the recharge measurement device.
