摘要： Saliency-based apparatus and methods for visual prostheses are disclosed. A saliency-based component processes video data output by a digital signal processor before the video data are input to the retinal stimulator. In a saliency-based method, an intensity stream is extracted from an input image, feature maps based on the intensity stream are developed, plural most salient regions of the input image are detected and one of the regions is selected as a highest saliency region.

摘要： The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the threshold of perception. Alternatively, electrode height may be measured directly to predict the threshold of perception. Also, impedance measurement may be used to quickly identify defective electrodes and proper electrode placement.

摘要： Applicant has proposed a combination of the subretinal and epiretinal methods by placing the electronics external to the eye, entering the eye through the pars plana and the piercing the retina (retinotomy) from inside the eye to stimulate subreintally. The present invention is an improved electrode array for subretinal stimulation. A hard polymer such as polyimide is biocompatible and strong for supporting an electrode array and supporting traces in a thin flex circuit array. In the present invention applicant takes advantage of the sharp nature of thin polyimide making a point on the end of the electrode array. This allows the flexible circuit electrode array to be both electrode array and surgical tool to cut the retinal and slide the array under the retina in a single action.
