1. An external device for use with an implantable medical device, comprising:
- a housing; and
a plurality of radiators within the housing, wherein a first one of the plurality of radiators is orthogonal to a second one of the plurality of radiators;
wherein the first and second radiators are configured to be energized simultaneously to telemeter data to an implantable medical device,wherein the first and second radiators are configured to be energized simultaneously to provide power to the implantable medical device, andwherein the first radiator is driven out of phase from the second radiator to telemeter data to the implantable medical device and to provide power to the implantable medical device.

Abstract
An improved embodiment of an external device for an implantable medical device system is described herein, where the external device has both circuitry for charging the implantable medical device and circuitry for telemetering data to and from the medical implant contained within a single housing. The external device in one embodiment includes orthogonal radiators in which both the radiators are used for data transfer, and in which at least one of the radiators is used for power transfer. Having charging and data telemetry circuitry fully integrated within a single external device conveniences both patient and clinician.
