Package for a Retinal Prosthesis

摘要

The present invention is an improved hermetic package for a retinal prosthesis implanted in the human body. The retinal prosthesis includes a flexible circuit electrode array suitable to stimulate the retina while connected to a hermetic package on the outside of the eye, the hermetic package including a cover and a base where the cover is bonded to the base such that the cover and base form the hermetic package.

主权项

1. A retinal prosthesis comprising:
a biocompatible package comprising
a planar base, including an electrically non-conductive substrate andbiocompatible patterned metallization on the non-conductive substrate,a circuit attached directly to a first side of the base wherein the circuit is smaller than the base, anda rounded cover, the base and the rounded cover forming the biocompatible package; a molded polymer body suitable to attach the biocompatible package to a sclera; and a flexible circuit electrically connected to the circuit, the flexible circuit extending from the biocompatible package and suitable to pass through a pars plana and having an array of electrodes suitable to stimulate retinal tissue.
