Retinal prosthesis and method of manufacturing a retinal prosthesis

摘要

The present invention is an improved package and configuration for an implantable retinal prosthesis. The retinal prosthesis of the present invention includes an electrode array suitable to be mounted in close proximity to a retina, an electronics package and inductive receiving coil mounted next to each other on a strap surrounding the sclera so that the height above the sclera of the prosthesis is minimized.

主权项

1. An implantable retinal prosthesis comprising:
a molded polymer body including a strap; a hermetic electronics package mounted to the polymer body including:
a. a rigid base, including an electrically non-conductive substrate and a plurality of electrically conductive vias through the electrically non-conductive substrate,b. an integrated circuit attached directly to the base and electrically connected to at least one of the plurality of electrically conductive vias,c. a passive circuit within the hermetic electronics package; andd. a rigid cover bonded to the base; and a secondary inductive coil embedded within the molded polymer body wherein the molded polymer body holds the secondary inductive coil in adjacent and coplanar, but not coaxial, alignment with the hermetic electronics package, the secondary inductive coil electrically coupled to the electronics package and powering the circuits in the electronics package.
