    摘要: The present invention relates to a retina implant for the functional electrostimulation of a retina as a function of incident light. The retina implant has a stimulation chip that is designed to be implanted in the area of the retina of an eye. It further includes a radiation receiver that provides energy for the stimulation chip as a function of invisible radiation that occurs. In accordance with one aspect of the present invention, the radiation receiver is designed so as to be implanted in the area of the eye in a fashion spatially separated from the stimulation chip. The stimulation chip also has decoupling means in order to separate invisible scattered radiation from impinging visible light.

    摘要: An active retina implant has a multiplicity of pixel elements that convert incident light into electric stimulation signals for cells of the retina with which stimulation electrodes are to make contact. Each pixel element is provided with at least one image cell that converts incident light into electric signals, there being provided at least one amplifier whose input is connected to the image cell and whose output is connected to at least one stimulation electrode to which it supplies a stimulation signal. Also provided is an energy supply which provides externally coupled external energy as supply voltage for the image cells and the amplifiers. The image cell has a logarithmic characteristic according to which incident light of specific intensity is converted into electric signals of specific amplitude. The stimulation signal is supplied in the form of analog voltage pulses of specific pulse length and pulse spacings, the pulse amplitude being a function of the intensity of the incident light.

    摘要: A retina implant including a chip adapted to be implanted into the interior of eye in subretinal contact with the retina. The chip has a plurality of pixel elements on a side thereof facing the lens for receiving an image projected into the retina and a plurality of electrodes for stimulating retina cells. The implants further includes a receiver coil for inductively coupling thereinto electromagnetic energy. The receiver coil coupled to a means for converting an alternating voltage induced into the receiver coil in a direct voltage suited for supplying the chip. The receiver coil is configured as a component separate from the chip, and for being positioned on the eye ball outside the sclera. The chip is connected to the receiver coil via a connecting lead which, in the implanted condition interconnects the interior and the exterior of the eye ball.
