External powering of implantable medical device dependent on energy of provided therapy
First Claim
1. A system, comprising:
- an implantable medical device for providing stimulation therapy;
a first external power device;
a second external power device; and
an external data communication device that is configured to characterize, based on one or more parameters of the stimulation therapy, the stimulation therapy as high energy therapy or low energy therapy, wherein the stimulation therapy is characterized as high energy therapy when its relative energy is greater than a threshold and low energy therapy when its relative energy is less than the threshold,wherein the first external power device is used to provide power to the implantable medical device when the stimulation therapy is characterized by the external data communication device as low energy therapy,and wherein the second external power device is used to provide power to the implantable medical device when the stimulation therapy is characterized by the external data communication device as high energy therapy.

Abstract
An implantable medical device system includes an implantable medical device for providing stimulation therapy and two external power sources. A first external power source is used to power the implantable medical device when the stimulation therapy is low energy therapy. For example, the first external power device may be utilized to periodically recharge a battery in the implantable medical device. The second external power device may be utilized to power the implantable medical device when the stimulation therapy is high energy therapy. The second external power device may be a disposable patch that is affixed to a patient'"'"'s skin to provide continuous power to the implantable medical device. The implantable medical device may communicate data to such a power device to cause it to adjust a strength of the charging field that it generates.
