    Abstract: Described is a system for controlling epidural spinal cord stimulation. Using an Unscented Kalman Filter (UKF), the system receives sensed physiological signals from a subject and, based on the sensed physiological signals, estimating an unobservable state of a target area on the subject. A central pattern generator is then used to generate a stimulation pattern based on the unobservable state. The stimulation pattern is applied to the target area (e.g., spinal cord) of the subject using an electrode array. Receiving feedback, the UKF continuously updates a model of the spinal cord, which results in adjustment of the stimulation pattern as necessary.

    Abstract: In some examples, a chronic implantable neurostimulator supports trial and chronic modes of operation. In addition, in some examples, the neurostimulator can alternatively include one or more sensors that may or may not function differently in trial and chronic modes. The device may be designed to be used as both a trial neurostimulator and a permanent, or chronic, neurostimulator. A trial neurostimulation period can be used to evaluate the efficacy of the therapy. A percutaneous or implantable trial neurostimulator is used for the trial neurostimulation period. In most cases, the trial period is successful, in which case the trial stimulator is explanted and replaced with a permanent, i.e., “chronic,” implantable stimulator. In accordance with the disclosure, an implantable neurostimulator supports both trial neurostimulation and chronic neurostimulation in the event trial stimulation is successful.

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.

Vestibular (and startling/surprise related) data indicative of a user's vestibular (and startling/surprise related) state is extracted from the one or more signals and used to determine whether a user is undergoing an event such as a fall or a startling movement. When it is determined that a user is undergoing an event, the processor of the wearable safety device transmits an activation signal to the safety device. Optionally, the processor may transmit data and information related to the vestibular (and startling/surprise related) system and recorded signals to a data repository.

  • Patent number: 9968329
    Abstract: A processing device detects a medical device and sends an audio wake-up signal to the medical device, wherein the audio wake-up signal causes the medical device to transition from a low power state to a higher power state. The processing device receives a diagnostic audio signal from the medical device after sending the audio wake-up signal. The processing device processes the diagnostic audio signal to determine medical information of a patient, the medical information comprising at least one of heart beat information or breathing information of the patient. The processing device performs at least one of storing the medical information or transmitting the medical information to a remote computing device.

  • Patent number: 9962542
    Abstract: Systems and methods for deep brain electrode placement and deep brain stimulation (DBS) for treatment of conditions such as obesity are disclosed. In one example approach, during placement of a deep brain stimulating electrode in a target region of the brain of a patient, a temperature of brown adipose tissue (BAT) may be monitored, e.g., via a supraclavicular temperature sensor implanted in the patient, and used to identify an optimal location of electrode stimulation which causes an increase in BAT temperature. Additionally, BAT temperature measurements may be used to provide regulated closed-loop control to increase efficiency of DBS while reducing energy consumption of the pulse generator. Further, core temperature measurements may be obtained from the electrode in the brain and used to adjust DBS.

  • Patent number: 9962543
    Abstract: In some embodiments, a paddle lead is implanted within a patient such that the electrodes are positioned within the cervical or thoracic spinal levels. An electrode combination on a first row of electrodes can be determined that is effective for a first pain location with minimal effects on other regions of the body. The first pain location can be addressed by stimulating a first dorsal column fiber due to the relatively fine electrical field resolution achievable by the multiple columns. Then, another electrode combination on a second row of electrodes can be determined for a second pain location with minimal effects on other regions. The second pain location could be addressed by stimulating a second dorsal column fiber. After the determination of the appropriate electrodes for stimulation, the patient's IPG can be programmed to deliver pulses using the first and second rows according to the determined electrode combinations.

  • Patent number: 9956421
    Abstract: Designs and methods of construction for an implantable medical device employ an internal support structure. The single-piece support structure holds various electronic components such as a communication coil and a circuit board, and further is affixed to a battery, thus providing a subassembly that is mechanically robust. The support structure further provides electrical isolation between these and other components. A method of construction allows for the subassembly to be adhered to a case of the implantable medical device at the support structure, and possibly also at the battery, without electrically shorting the battery to the case.
