Medical device recharge systems using a controller in wireless communication with a separate recharge device
First Claim
1. A method of recharging an implantable medical device, comprising:
- initiating wireless communications between a first controller and a first recharge device that provide first recharge instructions from the first controller to the first recharge device to control recharging;
transferring recharge energy from the first recharge device to the implantable medical device in accordance with the first recharge instructions;
initiating wireless communications between the first controller and a second recharge device that provide second recharge instructions from the first controller to the second recharge device to control recharging; and
transferring recharge energy from the second recharge device to the implantable medical device in accordance with the second recharge instructions.

Abstract
Medical device recharging systems include a controller and a separate recharge device that communicate wirelessly together to provide recharging to an implantable medical device. Either the controller or the recharge device may also communicate wirelessly with the implantable medical device to obtain recharge status and other information. There may be multiple recharge devices present within communication range of the controller, and the controller may determine which recharge device to activate depending upon proximity of each recharge device to the implantable medical device. The controller may allow the recharge device that is active at any given time to change so that the patient having the implantable medical device can move about in the area where the recharge devices are located while recharging continues.

12. A medical system, comprising:
-
a first controller having a wireless communication circuit; a first recharge device having a wireless communication circuit in wireless communication with the wireless communication circuit of the first controller and having a wireless recharge circuit, the first recharge device receives first recharge instructions from the first controller and generates recharge energy in the recharge circuit based on the first recharge instructions; an implantable medical device having a wireless recharge circuit having wireless coupling to the wireless recharge circuit of the first recharge device to receive recharge energy from the first recharge device; and a second recharge device having a wireless communication circuit and a wireless recharge circuit, the controller initiates wireless communications with the second recharge device that provide second recharge instructions from the first controller to the second recharge device to control recharging, and wherein the second recharge device transfers recharge energy to the implantable medical device in accordance with the second recharge instructions through a coupling of the wireless recharge circuit of the second recharge device and the wireless recharge circuit of the implantable medical device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
