TIME TO NEXT RECHARGE SESSION FEEDBACK WHILE RECHARGING AN IMPLANTABLE MEDICAL DEVICE, SYSTEM AND METHOD THEREFORE
First Claim
1. A recharge management system, comprising;
- an implantable medical device having a rechargeable power source;
an external charger configured to charge said rechargeable power source when placed in proximity to said implantable medical device;
electronic componentry, operatively coupled to said implantable medical device, configured to determine said recharge interval should said recharging session not continue; and
a user output, operatively coupled to said electronic componentry, configured to communicate said recharge interval to a user.

Abstract
A system and method for determining, during a recharge session, an amount of time until a subsequent recharge session is required to charge a rechargeable power source of an implantable medical device. A model allows a determination of the time until recharge without suspending charging during the recharge session by basing the determination on an initial measured battery voltage and a present current into the rechargeable power source. Alternatively, charging is suspended during the recharge session, and voltage measurements are taken, after which time charging is resumed, without patient input or suspending the recharge session.
