  • Publication number: 20210378574
    Abstract: Devices, systems and techniques are provided to facilitate chronic monitoring of biological signals. An implant device can include a set of branch portions. Each branch portion can include multiple electrodes disposed on a bottom surface and can have vias that connect the electrode to a trace on the top of the branch portion. Each branch portion can include a hole through which a connector (e.g., suture) can be pulled. The connector can also be threaded through a hole in a curved arm of an implantation tool, To implant the implant device, the implantation tool can be inserted through an incision, moved to a target location and stabilized. An end of the connector can then be pulled, which can cause the implant device to move to the target location. The implant device can then be stabilized and the implantation tool explanted.

  • Publication number: 20210298663
    Abstract: A method of detecting a seizure status of a subject includes collecting first data from a first accelerometer positioned on a first limb of the subject and a second data from a second accelerometer positioned on a torso of the subject, determining that one of the first accelerometer or the second accelerometer provides a better indication (e.g., greater level of sensitivity or a lesser level of a false positive rate) by comparing the first data and the second data, detecting an indication of the seizure status of the subject using at least one of the first data and the second data, and generating an alert in response to the detection of the indication of the seizure status of the subject.

  • Patent number: 11129563
    Abstract: An ophthalmic device includes an enclosure, an electromyography sensor, and a controller. The enclosure is configured to mount in or on an eye. The enclosure further includes a first material and a second material disposed within the first material. The electromyography sensor is adapted to measure electrical activity of a muscle of the eye proximate to a first annular region of the ophthalmic device when the ophthalmic device is mounted in or on the eye. The electromyography sensor includes a first electrode and a second electrode, each positioned within the first annular region between the first material and at least a portion of the second material. The controller, coupled to the electromyography sensor, stores instructions that when executed causes the ophthalmic device to perform operations including acquiring a first signal representative of the electrical activity of the muscle by measuring the electrical activity with the electromyography sensor.

  • Patent number: 11033220
    Abstract: A method of detecting a subject's physiological status, seizure state, or seizure type with limb-based accelerometers identifying a favored accelerometer or limb that provides a better sensitivity or false positive rate as compared to other accelerometers or limbs. The detection method may include determining whether the seizure conforms with an anticipated seizure type, and determining whether to base a seizure detection on data from the favored or un-favored accelerometers or limbs. The method may also include applying a weighing factor to base the detection on data obtained primarily from the favored accelerometer or limb or to not rely on data obtained primarily from un-favored accelerometers or limbs. The method may also include comparing data obtained from a favored accelerometer or limb with data obtained from other accelerometers or limbs or obtained from detection devices using ECG or EEG. An alert may be generated based on the detection of a seizure.

  • Patent number: 10773075
    Abstract: An electrode cuff for placement around a peripheral nerve can include one or more protrusions extending from a tissue-contacting surface of the electrode cuff. A protrusion can include one or more electrodes and can have a blunt distal end. The protrusion(s) can be driven into the nerve using a driving tool designed to apply mechanical oscillations and/or swift mechanical force to the electrode cuff. The mechanical oscillations and/or swift mechanical force can insert the blunt distal ends of the protrusions into the nerve without damaging fascicles within the nerve. During implantation, a sensor associated with the driving tool and/or the electrode cuff can provide dynamic feedback to a controller for controlling the driving tool. The sensor may detect pressure, temperature, acoustic activity, and/or electrical activity to indicate when the protrusions have pierced the epineurium, allowing the controller to cease the driving tool and thus avoid damage to the fascicles.
