Abstract
A system includes a first implantable medical device configured to receive a first far field radiative signal at a first frequency from an external transmitter to charge a first charge storage device. The first implantable medical device includes a first therapy delivery unit powered by the first charge storage device. The first therapy delivery unit delivers a first therapy to a first target tissue of a patient. The system also includes a second implantable medical device configured to receive a second far field radiative signal at a second frequency from the external transmitter to charge a second charge storage device. The second implantable medical device includes a second therapy delivery unit powered by the second charge storage device. The second therapy delivery unit delivers a second therapy to a second target tissue of the patient.
