  • Patent number: 10238863
    Abstract: Percutaneously advanced, distally into tissue of a subject, are (i) an implant, including an electrode and an anchor, and (ii) a tool. The tool includes an implant-storage member that houses the implant, and shaped to define a distal opening, and (b) a delivery manipulator, configured to facilitate bidirectional movement of the implant through the distal opening. Subsequently, the anchor and the electrode are exposed from the implant-storage member by withdrawing the implant-storage member proximally with respect to the implant. While the anchor and the electrode remain exposed from the implant-storage member, the implant is repositioned within the tissue by moving the implant, the implant-storage member, and the delivery manipulator with respect to the tissue. Subsequently, the tool is decoupled from the implant, and the tool is removed from the subject. Other embodiments are also described.

  • Patent number: 10220202
    Abstract: A flexible circuit electrode array with more than one layer of metal traces comprising: a polymer base layer; more than one layer of metal traces, separated by polymer layers, deposited on the polymer base layer, including electrodes suitable to stimulate neural tissue; and a polymer top layer deposited on the polymer base layer and the metal traces. Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, or cortical stimulation many purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow.

  • Patent number: 10179020
    Abstract: The present disclosure relates to devices, systems and methods for evaluating the success of a treatment applied to tissue in a patient, such as a radio frequency ablative treatment used to neuromodulate nerves associated with the renal artery. A system monitors parameters or values generated during the course of a treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of the likelihood that a completed treatment was technically successful. In other embodiments, parameters or values generated during the course of an incomplete treatment (such as due to high temperature or high impedance conditions) may be evaluated to provide additional instructions or feedback to an operator.
