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, a patient programmer may include both an internal antenna for RF telemetry with an implantable medical device and a display. The patient programmer may include a processor or other control circuitry that selectively disables. i.e., turns off, the display during RF telemetry with the internal antenna to promote more reliable communication. The processor or control circuitry also may disable electronics associated with the display during a telemetry session. In this manner, the programmer can be configured to reduce the impact of electrical and electromagnetic noise on telemetry performance.

A stimulation device for screening therapeutic effects from electrical stimulation of electrically excitable tissue. The stimulation device includes inputs such that the user can easily select the polarity, amplitude, pulse width, and pulse rate of the respective stimulation signal applied on each of the implanted electrodes. Alternatively, the stimulation device automatically sets those parameters of the stimulation signal with parameters that have historically produced high ratings of therapeutic effect. The user then enters a rating of the therapeutic effect that results from the application of those stimulation signals on the implanted electrodes. The stimulation device is designed to also include a casing such that the stimulation device is adapted to be portable. Because the stimulation device of the present invention is also inexpensive, the user can carry this device around during normal daily activities of the user during the screening process. Consequently, parameters of the stimulation device that would result in optimum therapeutic effect for normal daily activities of the user can be determined more easily and more accurately.

摘要:
A mechanism for transferring energy from an external power source to an implantable medical device is disclosed. An antenna is positioned in proximity of the implantable medical device. The position of a core of the antenna is adjusted relative to the implantable medical device while the antenna is maintained substantially stationary. A frequency of transmission of a power source is adjusted, and the antenna is driven at the adjusted frequency to transfer energy transcutaneously to the implantable medical device. In one embodiment, the frequency of transmission is selected based on an amplitude of a signal in the antenna.
