Abstract:
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.
