    摘要: An implant stimulator device uses tantalum and tantalum pentoxide as a system for the conveyance of electrical stimulation pulses from stimulus-forming circuitry contained within an hermetic enclosure to the saline fluids of body tissue to be stimulated. Internal coupling capacitors are not used, yet the danger of having DC current flow to the saline fluids is eliminated. A preferred embodiment provides a multiplicity of electrode contacts made from sintered, anodized tantalum, connected via tantalum wire leads to tantalum feedthroughs into the hermetically sealed package containing the stimulus pulse-forming electronic circuitry. One or more counter electrode contacts (for monopolar or bipolar configurations, respectively) made of activated iridium, non-activated iridium, iridium in combination with a noble or non-noble metal, platinum, gold, or other metal which forms a low impedance contact with body fluids, is/are connected via platinum or other conductive metal leads to return feedthroughs. When powered-up, the stimulus generating circuit produces a steady polarizing potential of approximately half its maximum output voltage range, which potential is applied as a positive (anodizing) voltage to each tantalum electrode and associated lead and feedthrough, with respect to the counter electrode(s), which act as the reference point for the circuit.

    摘要: An addressable, implantable microstimulator is substantially encapsulated within a hermetically-sealed housing inert to body fluids, and of a size and shape capable of implantation in a living body, by expulsion through a hypodermic needle. Power and information for operating the microstimulator is received through a modulated, alternating magnetic field in which a coil is adapted to function as the secondary winding of a transformer. Electrical energy is stored in capacitor means and is released into the living body by controlled, stimulating pulses which pass through body fluids and tissue between the exposed electrodes of the microstimulator. Detection and decoding means within the microstimulator are provided for controlling the stimulating pulses in accordance with the modulation of the received, alternating magnetic field. Means for controllably recharging the capacitor is provided.

    摘要: A multichannel stimulation system includes a plurality of implantable microminiature stimulators (microstimulators), each being connected to a respective implanted electrode or electrode array. Each microstimulator is selectively operable as controlled by an external (non-implanted) control unit. The electrode or electrode array is implanted so as to contact nerves and/or tissue that is to be stimulated. Operating power is inductively coupled from the control unit to the microstimulators. An information signal is also coupled to the microstimulators to control which of the microstimulators is to be activated to provide a stimulation pulse to its respective electrode. In one embodiment, the invention provides a cochlear prosthesis with an intracochlear electrode array being implanted within the human cochlea, and with selected electrodes of the array being connected to individual ones of the plurality of microstimulators. The control unit of such cochlear prosthesis includes a small external transmitter coil that is worn next to the skin where the microstimulators are implanted. The control unit generates a power signal and an information signal for powering and controlling the cochlear prosthesis.

    摘要: An electronics filter circuit includes an electromechanical resonator that is mounted directly to the surface of a silicon integrated circuit, rather than being a surface mounted or leaded filter can on a circuit board. This filter circuit allows the integrated circuit electronic package to be significantly smaller than a conventional electromechanical resonator package. The electromechanical resonator may be protected during processing and during use with a protective cover that is made of a material such as titanium. The protective cover is attached to the integrated circuit chip.

    摘要: A method and apparatus for improving visual acuity when providing a visual image from a “high” resolution input device to a “low” resolution output device. The described invention is of particular use when the output device is an array of electrodes as part of a retinal prosthesis used to restore vision to a visually-impaired patient. In that various limitations may, within the foreseeable future, limit the density of such an electrode array (and thus the resolution of the output image), the present invention teaches techniques to assign processed pixel subsets of a higher resolution image to a single electrode. By varying the pixel subsets, e.g., by jittering, and/or altering the processing criteria, the perceived visual acuity may be further improved. Alternatively and additionally, such processing may be further extended to drive neighboring electrodes in combination to thus stimulate virtual electrode sites and thus further enhance visual acuity.
