Second Sight | Date: 2016-10-04

An implantable micro-miniature device is disclosed. The device comprises a thin hermetic insulating coating and at least one thin metal secondary coating over the hermetic insulating layer in order to protect the insulating layer from the erosive action of body fluids or the like. In one embodiment the insulating layer is ion beam assisted deposited (IBAD) alumina and the secondary coating is titanium. The device may be a small electronic device such as a silicon integrated circuit chip. The thickness of the insulating layer may be ten microns or less and the thickness of the secondary layer may be between about 0.1 and about 15 microns.

The present invention is an improved fitting and training system for a visual prosthesis. A patient, using the visual prosthesis observes a display and indicates location, movement, shape or other properties of the display image to provide for improved fitting and training. In one embodiment, the patient uses a touch screen monitor which displays an image. The patient touches the monitor at the location where the patient perceives the image. The system then corrects the image to the location indicated by the patient. In another embodiment a patient observes an image moving across the touch screen monitor and indicates by moving their hand across the monitor which direction they believe the image is moving. The system can then rotate the image to match the image perceived by the patient.


The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package, that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a studbump connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.

The present invention is an improved fitting and training system for a visual prosthesis. Fitting a visual prosthesis through automated means is challenging and fitting a visual prosthesis manually is tedious for clinician and patent, and provides great opportunity for error. A hybrid of computer controlled and manual fitting provides effective, efficient and controlled fitting process. The process includes testing a group of electrodes in random order by providing a prompt followed by stimulation and the patient responding if they saw a percept. After each set, a maximum likelihood algorithm is used to determine the next stimulation level, or if further stimulation is needed for each electrode.


The present invention is a new configuration for the external portion of a visual prosthesis in the form of a visor or glasses, including a frame supported by a users nose and ears. The video processing unit is adapted to be connected by temple portions of the visor and rest on the users upper back behind the users neck, or behind the users head. Controls for the video processor are on one or both temple portions of the visor.
