  • Patent number: 11890101
    Abstract: Systems and methods for calibrating an orientation of an implantable device in a patient is described. An exemplary system includes a calibration circuit that can receive acceleration information sensed from an implantable medical device (IMD) implanted in a patient, and receive reference acceleration information sensed from a reference device associated with the patient. The acceleration information and the reference acceleration information are acquired when the patient assumes a first posture or in a first position. The calibration circuit determines a spatial relationship between an orientation of the IMD and a reference orientation of the reference device using the received acceleration information and the received reference acceleration information, and calibrate subsequent acceleration information sensed from the IMD using the determined spatial relationship to correct for the orientation of the IMD.

  • Patent number: 11109787
    Abstract: A device for obtaining an electrical conductance reading from a patient includes a sensor head for contacting a patient's skin. The device includes a primary conductive tip positioned on the sensor head and an ancillary conductive tip positioned on the sensor head to contact a different portion of the patient's skin than the primary conductive tip. The primary conductive tip and the ancillary conductive tip are electrically isolated from each other. The primary conductive tip and the ancillary conductive tip are configured to contact a patient's skin when the sensor head is placed against the patient's skin to obtain independent measurements of electrical conductance.

  • 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.
