摘要： A positionally sensitive spinal cord stimulation apparatus and method using near-infrared (NIR) reflectometry are provided for automatic adjustments of spinal cord stimulation. The system comprises an electrode assembly with an integrated optical fiber sensor for sensing spinal cord position. The integrated optical fiber sensor, comprising a pair of optical elements for emitting light from an IR emitter and for collecting reflected light into a photodetector, determines a set of measured photocurrents. As the spinal cord changes position, the angles of incidence for light from the IR emitter and the measured optical intensities change. Electrode pulse characteristics are adjusted in real time, based on the set of measured optical intensities, to minimize changes in stimulation perceived by the patient during motion. The system includes automatic calibration of the optical fiber sensor when the patient is at rest, and a patient orientation detection.

摘要： A computer implemented system and method facilitates a cycle of generation, sharing, and refinement of volumes related to stimulation of anatomical tissue, such as brain or spinal cord stimulation. Such volumes can include target stimulation volumes, side effect volumes, and volumes of estimated activation. A computer system and method also facilitates analysis of groups of volumes, including analysis of differences and/or commonalities between different groups of volumes.

摘要： Electrical energy is transcutaneously transmitted at a plurality of different frequencies to an implanted medical device. The magnitude of the transmitted electrical energy respectively measured at the plurality of frequencies. One of the frequencies is selected based on the measured magnitude of the electrical energy (e.g., the frequency at which the measured magnitude of the electrical energy is the greatest). A depth level at which the medical device is implanted within the patient is determined based on the selected frequency. For example, the depth level may be determined to be relatively shallow if the selected frequency is relatively high, and relatively deep if the selected frequency is relative low. A charge strength threshold at which a charge strength indicator generates a user-discernible signal can then be set based on the determined depth level.

摘要： A neurostimulation system having an external or an implantable pulse generator programmed to innervate a specific nerve or group of nerves in a patient through an electrode as a mode of treatment, having a patient remote that wirelessly communicates with the pulse generator to increase stimulation, decrease stimulation, and provide indications to a patient regarding the status of the neurostimulation system. The patient remote can allow for adjustment of stimulation power within a clinically effective range and for turning on and turning off the pulse generator. The patient remote and neurostimulation system can also store a stimulation level when the pulse generator is turned off and automatically restore the pulse generator to the stored stimulation level when the pulse generator is turned on.

摘要： Disclosed in an improved medical implantable device system including an improved external charger that is able to communicate with an external controller and IPG using the communication protocol (e.g., FSK) used to implement communications between the external controller and the implant. The external controller as modified uses its charging coil to charge the implant, and also to communicate with the other devices in the system. As such, the external charger is provided with transceiver circuitry operating in accordance with the protocol, and also includes tuning circuitry to tune the coil as necessary for communications or charging. Communication or charging access to the charging coil in the external charger is time multiplexed. The disclosed system allows charging information to be provided to the user interface of the external controller so that it can be reviewed by the user, who may take corrective action if necessary. Also disclosed are schemes for synchronizing and arbitrating communications between the devices in the system.

摘要： This document discusses, among other things, systems and methods to acclimate a patient to therapy from an implantable medical device. For instance, an implantable medical device can include pulse generation circuitry, sensing circuitry, and a controller. The pulse generation circuitry can generate electrical pulses. The sensing circuitry can be for sensing cardiac electrical activity of the patient. In an example, the controller can detect cardiac events that define pacing timing intervals and control the delivery of electrical pulses in accordance with a programmed mode. The controller can be programmed to provide instructions to the pulse generation circuitry to deliver electrical pulses to the heart of a patient. In an example, the electrical pulses can be based on a therapy parameter. The controller can be configured to adjust the therapy parameter according to an acclimation profile to acclimate the patient to a stimulation therapy.

摘要： Changes in electrical stimulation therapy delivered via a medical device are coordinated with Functional Magnetic Resonance Imaging (fMRI) scans. In one example, a medical device delivers electrical stimulation therapy to a patient in an MRI unit, where the medical device is configured to cycle electrical stimulation therapy between a plurality of stimulation states. An indication that the medical device will cycle the electrical stimulation therapy or has cycled the electrical stimulation therapy while the patient is in the MRI unit or being imaged by the MRI unit is generated, and an MRI scan of the patient via an MRI workstation is initiated based on the indication. In another example, a medical device detects activation of an MRI scan and automatically switches stimulation states based upon the detection of the MRI scan, such that the scan is associated with a particular stimulation state.

摘要： A wireless charger for automatically tuning an optimum frequency to inductively charge a rechargeable battery of an implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body is provided. The charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An optimization circuit detects a reflected impedance of the charging coil through a reflected impedance sensor, and select an optimum frequency of a charging signal supplied to the charging coil based on the detected reflected impedances of a plurality of charging frequencies in a selected frequency range. Advantageously, the optimum charging frequency provides a more efficient way to charge the IPG's rechargeable battery.
