Abstract: A holster that may be donned in a first configuration for charging a pectorally implanted medical device on the patient's right side, a second configuration for charging a pectorally implanted medical device on the patient's left side, or a third configuration for use as a waist belt for charging a pectorally implanted medical device on either side of the patient.

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.

Abstract: System and method for estimating a time to recharge a rechargeable power source of an implantable medical device. A plurality of measured parameters relating to the implantable medical device and an external charging device are applied to a model of recharging performance and an estimate is provided to a patient, perhaps in advance of charging. Once charging has begun, updated estimates can be provided until charging is complete. Once charging is complete, the model may be updated to reflect any differences in the estimated time to complete charging and the actual time required to complete charging. The model may be based on limitations to the rate at which charge may be transferred to the rechargeable power source over a plurality of intervals.

Abstract: A holster that may be donned for charging a pectorally-implanted implantable medical device (IMD) on the patient's right or left side. The holster includes a torso strap that encircles a patient's torso. The torso strap includes first and second ends and an intermediate portion there between. A shoulder strap is provided that extends over either the right or left shoulder of a patient. The shoulder strap includes a holder to house at least an antenna portion of an external charging device used to charge the IMD. The shoulder strap includes first and second ends, at least one of which may be selectably positioned at any point along the intermediate portion of the torso strap to maintain the antenna of the recharger in close proximity to the IMD to reduce charge times.
