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.
