摘要:
The present invention provides a flexible circuit electrode array adapted for neural stimulation, comprising: a polymer base layer; metal traces deposited on said polymer base layer, including electrodes suitable to stimulate neural tissue; a polymer top layer deposited on said polymer base layer and said metal traces at least one tack opening; wherein said polymer base layer, said metal traces and said polymer top layer are thermoformed in a three dimensional shape. The present invention provides further a method of making a flexible circuit electrode array comprising depositing a polymer base layer; depositing metal on said polymer base layer; patterning said metal to form metal traces; depositing a polymer top layer on said polymer base layer and said metal traces; preparing at least one tack opening; and heating said flexible circuit electrode array in a mold to form a three dimensional shape in said flexible circuit electrode array.

A method of editing a video configuration file downloadable to or from a video processing unit of a fitting system for a visual prosthesis is shown. The visual prosthesis has a plurality of electrodes and the video configuration file defines mapping of a video signal captured from a camera of the visual prosthesis to an electrical signal for the electrodes. The editing controls a brightness map for an individual electrode or electrode groups, together with a temporal stimulation pattern to which an individual electrode or electrode groups are assigned. A related computer-operated system is also disclosed.
摘要:
The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual patient. By recording neural response to a predetermined input stimulus, one can alter that input stimulus to the needs of an individual patient. A minimum input stimulus is applied to a patient, followed by recording neural response in the vicinity of the input stimulus. By alternating stimulation and recording at gradually increasing levels, one can determine the minimum input that creates a neural response, thereby identifying the threshold stimulation level. One can further determine a maximum level by increasing stimulus until a predetermined maximum neural response is obtained.

An implantable device, comprising a rigid substrate having an electrically non-conductive portion; a plurality of electrically conductive vias through said electrically non-conductive portion, said vias and electrically non-conductive portion forming said rigid substrate; metal traces on said rigid substrate electrically connected to said conductive vias; a circuit attached to said metal traces; a braze stop trace surrounding said metal traces; a cover bonded to said rigid substrate with a braze, said cover and said rigid substrate forming a hermetic package; wherein said braze stop trace prevents said braze from contacting said metal traces.
摘要:
The object of the current invention is to restore color vision, in whole or in part, by electrically stimulating undamaged retinal cells (120), which remain in patients with lost or degraded visual function. The invention is a retinal color prosthesis. Functionally, there are three main parts, one external to the eye (312), one internal to the eye, and a means for communicating between the two parts. The external part has an imaging means, an eye-tracker, a head-motion tracker (131), a data processor, a patient's controller, a physician's local, remote controller, and a telemetry means (118).
