  • Patent number: 10525252
    Abstract: An architecture is disclosed for an Implantable Pulse Generator having improved compliance voltage monitoring and adjustment software and hardware. Software specifies which stimulation pulses are to be measured as relevant to monitoring and adjusting the compliance voltage. Preferably, specifying such pulses occurs by setting a compliance monitoring instruction (e.g., a bit) in the program that defines the pulse, and the compliance monitor bit instruction may be set at a memory location defining a particular pulse phase during which the compliance voltage should be monitored. When a compliance monitor instruction issues, the active electrode node voltages are monitored and compared to desired ranges to determine whether they are high or low. Compliance logic operates on these high/low signals and processes them to decide whether to issue a compliance voltage interrupt to the microcontroller, which can then command the compliance voltage generator to increase or decrease the compliance voltage.

  • Patent number: 9821161
    Abstract: 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.

  • Patent number: 9814883
    Abstract: Methods and circuitry for determining an implanted-neurostimulator patient's position, and adjusting a situation program delivered by the neurostimulator based on the determined position, is disclosed. Impedance measurements of the patient's tissue are taken at the neurostimulator's electrodes, which measurements can comprise complex impedance measurements (magnitude and phase) taken at different frequencies. Such impedance measurements, which can be taken interleaved with stimulation therapy, are used to determine an “impedance fingerprint.” This fingerprint can be compared to other known fingerprints stored in the IPG, which known fingerprints are associated with particular stimulation programs. When a measured fingerprint matches one stored in the IPG, the stimulation program associated with the stored fingerprint is automatically used for patient therapy.

  • Patent number: 9814887
    Abstract: A medical device and associated method record signals from each real axis of a multi-axis sensor. An optimal axis for monitoring a physiological signal of the patient is identified from the real axes of the multi-axis sensor and multiple virtual axes. Coordinates defining the optimal axis are stored as respective weighting factors of the signals from each real axis of the multi-axis sensor. A metric of the physiological signal is determined using the multi-axis sensor signals and the weighting factors.
