Abstract: Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals. For example, a system may assist a clinician in identifying one or more electrode combinations for sensing a brain signal. In another example, a user interface may display brain signal information and values of a stimulation parameter at least partially defining electrical stimulation delivered to a patient when the brain signal information was sensed.

Abstract: A medical device with closed-loop responsive stimulation may include techniques to mitigate the impact on the therapy output of noise coupled into the medical device. A medical device according to this disclosure may determine the presence of noise and alter the closed loop policy to provide the necessary therapy to the patient and avoid prolonged under stimulation caused by the noise. The medical device may continue therapy, while testing for noise. When the device determines the noise level no longer affects the output therapy, the device may return the closed loop policy to a no-noise mode of operation. The medical device may also include techniques to mitigate the impact of manual adjustment while the medical device is subject to noise or is responding to changes in the patient's physiological signals.

Abstract: A hardware based block moving controller of an active device such as an implantable medical device that provides electrical stimulation reads a parameter data from a block of memory and then writes the parameter data to a designated register set of a component that performs an active function. The block of memory may include data that specifies a size of the block of memory to be moved to the register set. The block of memory may also include data that indicates a number of triggers to skip before moving a next block of memory to the register set. A trigger that causes the block moving controller to move the data from the block of memory to the register set may be generated in various ways such as through operation of the component having the register set or by a separate timer.

Abstract: A hardware based block moving controller of an active device such as an implantable medical device that provides electrical stimulation reads a parameter data from a block of memory and then writes the parameter data to a designated register set of a component that performs an active function. The block of memory may include data that specifies a size of the block of memory to be moved to the register set. Multiple individual block mover components of the controller may move respective blocks, each responsive to a dedicated trigger or to a same trigger. Furthermore, a given block mover or individual block mover component may have multiple selectable triggers. The block moving hardware based controller may have one or more memory devices to access, and the firmware may write to one memory while the block moving hardware based controller may read from another.

Abstract: The disclosure relates to an electrical trial stimulator that stores multiple applications to selectively emulate the operation of different chronically implanted stimulators. Each application corresponds to a different chronically implanted stimulator. Upon selection of a particular application, the stimulator executes a set of instructions to emulate the operation of a chronically implanted stimulator that corresponds to the application. The multi-application stimulator permits a physician to select an application for stimulation therapy, and evaluate efficacy of a particular chronically implanted stimulator. In addition, the physician may select any of the other stimulation applications to emulate other stimulators. The different stimulation applications may correspond to different stimulators that deliver a similar therapy, e.g., stimulators designed to deliver spinal cord stimulation for alleviation of chronic pain.
