Abstract: External power source, and system and method using such external power source, for an implantable medical device having therapeutic componentry and a secondary coil operatively coupled to the therapeutic componentry. A primary coil is capable of inductively energizing the secondary coil when externally placed in proximity of the secondary coil. A repositionable magnetic core associated with the primary coil is capable of being repositioned by a user of the external power source. An indicator is capable of providing the user with information relative to coupling between the primary coil and the secondary coil as a function of repositioning of the repositionable magnetic core.

Abstract: 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.

Abstract: An implantable medical device includes a control circuit for controlling the operation of the device and for obtaining physiological data from a patient in which the medical device is implanted. The implanted device also includes a communication circuit for transmitting the physiological data to an external device. A first power source is coupled to the control circuit and provides power to the control circuit. A second power source is coupled to the communication circuit and provides power to the communication circuit.

Abstract: An apparatus and method that allows a patient to access stored preset patient therapy programs, that are resident in a medical device, and to create personalized therapy programs or automatic timing therapy programs from preset therapy programs to accommodate the patient's particular activity. Alternatively, the patient can select and access stored preset patient therapy programs and combine at least two modified or unmodified preset therapy programs to create personalized therapy programs.

Abstract: A neurostimulation lead includes fiber optic cable. A human-implantable neurostimulator and neurostimulation lead each include an opto-electric transducer. The opto-electric transducers can be an optical transmitter, an optical receiver, or an optical transducer, that converts: electrical energy to optical energy; optical energy to electrical energy; or both electrical energy to optical energy and optical energy to electrical energy. Neurostimulation-lead electrodes can be activated, and/or lead-status information can be transmitted, over the fiber optic cable, between the neurostimulator and the neurostimulation lead. A neurostimulation-lead power converter may be coupled to a pulse generator of the neurostimulator such that the power converter derives and stores power for the lead from stimulation pulses received from the stimulation-pulse generator.

Alternatively, the patient can select and access stored preset patient therapy programs and combine at least two modified or unmodified preset therapy programs to create personalized therapy programs.

Abstract: An apparatus and method that will allow for external communication, via an external programmer, for positive device identification and for retrieval of device or patient information stored by an implantable medical device with a depleted power source. The external programmer will deliver energy to a secondary power source located inside the implanted device using RF telemetry sufficient to charge up the secondary power source, e.g., a small capacitor. The capacitor will charge up immediately within milliseconds. Once the secondary power source is sufficiently charged, it can be used to power up a controller having the stored information in the implantable medical device. Once the controller is operational, the implanted device will transmit device and patient information to the external programmer via RF telemetry.

Abstract: 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.
