Patent attributes
In general, the invention is directed to a patient programmer for an implantable medical device. The patient programmer may include one or more of a variety of features that may enhance performance, support mobility and compactness, or promote patient convenience. For example, the patient programmer may include an internal antenna for RF telemetry with the implantable medical device. The internal antenna may have a loop-like structure that defines a central aperture. A battery bay may extend at least partially into the antenna aperture from the patient programmer housing. One or more batteries may be mounted in the battery bay within the antenna aperture. In some cases, the batteries may contribute favorably to the RF load presented to the internal antenna. In particular, the batteries may present an additional load to the internal antenna, enhancing immunity to electrical and electromagnetic interference during telemetry sessions with the implantable medical device.
