An optical stimulation system includes a light source configured to produce light for optical stimulation; a light monitor; an optical lead coupled, or coupleable, to the light source and the light monitor; and a control module coupled, or coupleable, to the light source and the light monitor. The control module includes a memory, and a processor coupled to the memory and configured for receiving a request for verification or measurement of a light output value; in response to the request, receiving, from the light monitor, a measurement of light generated by the light source; and, based on the measurement, reporting a response to the request.

Systems and methods are disclosed to permit a patient to use his external controller to move the location of stimulation in an implantable stimulator system. The external controller can be programmed with a steering algorithm, which prompts the patient to enter certain data regarding their symptoms (e.g., pain), such as pain scores and stimulation coverage. Such data is preferably entered for a plurality of different regions of the patient's body. The algorithm can compute for each body regions a targeting precision value (TP), and from these values determine a steering vector D that suggests a direction and/or a magnitude that stimulation can be moved in the electrode array to more precisely target the patient's pain. The patient may then move the location of the stimulation in accordance with the steering vector using their external controller. The algorithm can be repeated if necessary to again move the stimulation.

User-specific neurostimulation settings are efficiently determined and optimized based on an optimized set of population-based neurostimulation settings. The population data are clustered and a set of test settings for a new user are selected as settings that efficiently discriminate between the clusters. User preference of the test settings are used to map the user to a particular cluster of settings, which can be used to determine user-specific neurostimulation settings. The user-based settings can be iteratively updated and/or optimized using information from the population data, such as by using average preference score surfaces in the population data to identify and/or filter new test settings for the user.

An example of a system for delivering neurostimulation may include a programming control circuit and a stimulation control circuit. The programming control circuit may be configured to generate stimulation parameters controlling delivery of the neurostimulation according to a stimulation configuration. The stimulation control circuit may be configured to specify the stimulation configuration, and may include volume definition circuitry and stimulation configuration circuitry. The volume definition circuitry may be configured to determine one or more test volumes, determine a clinical effect resulting from the one or more test volumes each being activated by the neurostimulation, and determine a target volume using the determined clinical effect. The stimulation configuration circuitry may be configured to generate the specified stimulation configuration for activating the target volume.

The presence mode allows for viewing presence of a feature in the selected signal(s). The presentation control circuit may be configured to allow for the selection of the signal(s) and the viewing mode, to determine a segment of each of the selected signal(s) for presentation according to the selected viewing mode, and to present the determined segment on the display screen.

The present invention relates to a system and method for replacing an implanted medical device with an implantable medical replacement device, wherein a programming device sends a command signal to the medical device to change an address of the medical device to a new address being different from an address of the replacement device to allow independent communication of the programming device with both the medical device and the replacement device.

The present invention provides improved methods for positioning of an implantable lead in a patient with an integrated EMG and stimulation clinician programmer. The integrated clinician programmer is coupled to the implantable lead, wherein the implantable lead comprises at least four electrodes, and to at least one EMG sensing electrode minimally invasively positioned on a skin surface or within the patient. The method comprises delivering a test stimulation at a stimulation amplitude level from the integrated clinician programmer to a nerve tissue of the patient with a principal electrode of the implantable lead. Test stimulations are delivered at a same stimulation amplitude level for a same period of time sequentially to each of the four electrodes of the implantable lead. A stimulation-induced EMG motor response is recorded with the integrated clinician programmer for each test stimulation on each electrode of the implantable lead via the at least one pair of EMG sensing electrodes so as to facilitate initial positioning of the implantable lead at a target stimulation region.
