Abstract:

A microelectrode array system used to sense physiological signals and stimulate physiological tissue to form signals is disclosed. The array includes a dielectric substrate and a two dimensional array of signal microelectrodes substantially perpendicular to and integrated on the dielectric substrate. At least one reference microelectrode is located adjacent to and integrated with the signal microelectrodes on the dielectric substrate. The reference microelectrodes are positioned on the dielectric substrate relative to the signal microelectrodes to enable a reduced level of electrical noise to be detected between the reference microelectrodes and the recording microelectrodes.

Abstract:

A system and method for electrically shielding a physiological pathway from electrical noise is disclosed. The method includes the operation of implanting at least one signal microelectrode into a patient such that the signal microelectrode is proximate to the physiological pathway. An additional operation includes substantially enclosing the microelectrode and a section of the physiological pathway with an electrical shielding wrap. The electrical shielding wrap includes a plurality of holes that enable fluid communication of physiological fluids between an inside and outside of the wrap.

US Classification:

600300, 607 88

Abstract:

A hybrid optical-electrical neural interface is disclosed and described. The neural interface can include an array () having a plurality of micro-optrodes (HO). The micro-optrodes () are capable of optical and optionally electrical stimulation and recording, allowing bidirectional, multi-modal communication with neural tissue. At least a portion of the plurality of micro-optrodes () are independently optically addressable and include an optical waveguide along each micro-optrode (HO). Combining optical stimulation with electrical recording can allow artifact-free recording from nearby electrodes and in some cases even the same electrode, which is difficult to achieve with combined electrical recording and stimulation. The optical waveguide is configured to direct light towards a distal end () of the micro-optrode, allowing focal stimulation and recording. Penetrating micro-optrodes () can allow access to deep tissue, while non-penetrating micro-optrodes can be used for extraneural stimulation.

Abstract:

A medical implant device () is disclosed that can protect and shield an implant () as the implant () moves through body tissue. The medical implant device () can comprise a main body portion () having a payload opening () to receive a payload (i.e., an implant). The medical implant device () can also comprise a tapered nose portion () at a front end () of the medical implant device () extending from the main body portion () and configured to penetrate body tissue. In addition, the medical implant device () can comprise a payload coupling interface () configured to couple the implant () to the main body portion ().

Abstract:

A technology is described for an electronic peripheral nerve stimulation system. The electronic nerve stimulation system can include a stimulation device and an electrode array. The stimulation device can be operable to generate a high-frequency alternating current. The electrode array can be operable to apply the high-frequency alternating current received from the stimulation device to selected subpopulations of peripheral nerve fibers within a peripheral nerve to block transmission of neural signals along the selected subpopulations of peripheral nerve fibers within the peripheral nerve.
