Abstract: A system for selecting therapy parameters for a neurostimulation system associated with a brain includes a device configured to sense biosignal activity from the brain and an optimizer. The optimizer is configured to select a target region of the brain for neuromodulation therapy, which target region minimizes the difference between real biosignals captured by the device and modeled biosignals. The optimizer is further configured to determine stimulation settings for neuromodulation therapy, which stimulation settings result in a modeled electrical characteristic of stimulation at a target region that satisfies a criterion.

Abstract: A lead fixation device for securing a first portion of a lead relative to a hole formed through a skull includes a skull attachment member having an upper surface and a lower surface and a bore extending through and between the upper surface and the lower surface. The lead fixation device also includes a lead compression mechanism integral with the skull attachment member and aligned with the bore of the skull attachment member. The lead compression mechanism defines a passageway through the lead fixation device, which passageway is characterized by a diameter that is defined by the lead compression mechanism. The lead compression mechanism is configured to transition the diameter from a first size to a second size greater than the first size upon insertion of an implant tool through the passageway, and from the second size to the first size upon removal of the implant tool from the passageway.

Abstract: An external data retrieval apparatus receives a low resolution version of a physiological signal from an active implantable medical device and determines if the physiological signal represents a clinically significant event. The apparatus provides an indication of such determination to the implantable medical device. If the physiological signal does represent a clinically significant event, the apparatus receives a full download of the physiological signal from the implantable device.

Abstract: A method of assessing electrical activity of a brain includes, for each of a plurality of electrical-activity records of the brain, applying a machine-learned ESC model to the record to classify the record as one of a seizure record or a non-seizure record, wherein each of record is sensed by a corresponding one of a plurality of sensing channels of an implanted medical device; for each seizure record in a set of seizure records, applying the machine-learned ESC model to the seizure record to classify the seizure record as one of a local-seizure record or a spread-seizure record, wherein the seizure record comprises a first seizure record captured by a first sensing channel and a second seizure record captured by a second sensing channel; and for each spread-seizure record in a set of spread-seizure records, applying a machine-learned SSC model to the spread-seizure record to classify the spread-seizure record as a type of seizure spread pattern.

Abstract: An implanted neurostimulation system is configured to sense episodes of electrographic events and determine durations of episodes. Durations of electrographic events sensed by the implanted neurostimulation system are mapped with seizure probability biomarkers derived from records of the electrographic events to create a mapping function. A seizure probability biomarker that has a value desired for the operation of the implanted neurostimulation system is selected. The duration mapped to the selected seizure probability biomarker is identified and programmed into a control module of the implanted neurostimulation system as a programmed parameter that triggers the operation by the implanted neurostimulation system. The process may be repeated for other operations of the implanted neurostimulation system.

Abstract: An external data retrieval apparatus receives a low resolution version of a physiological signal from an active implantable medical device and determines if the physiological signal represents a clinically significant event. The apparatus provides an indication of such determination to the implantable medical device. If the physiological signal does represent a clinically significant event, the apparatus receives a full download of the physiological signal from the implantable device.

Abstract: A lead fixation accessory configured to be positioned over a skull hole and to transition between an opened state and a closed state during a lead implant procedure protects against lead migration by providing a mechanism for securing the lead in place at the skull hole while a stylet is removed from the lead. The lead fixation accessory remains in place after the implant procedure to provide chronic lead stability. A lead stabilization tool configured to access and grip a lead through a slotted cannula during the lead implant procedure also protects against lead migration by providing a mechanism for securing the lead in place at a point where the lead exits the skull hole while the slotted cannula is removed from the skull hole and peeled away from the lead.

Abstract: A rotating platform has a peripheral wall to form a catch basin. A donut shaped wrapper housing can hold perhaps 50-100 cigarette wrappers facing inbound with a closed end projecting out an outer wall exit hole into the catch basin. Tobacco or any work material is dropped onto the center of the rotating platform which may be motor driven. Centripetal forces urge the work material into the wrappers. Empty wrapper channels feed the excess material into the catch basin. A lid prevents loss of work material.
