The present invention is a cortical visual prosthesis. The cortical visual prosthesis includes an implanted portion and an external portion. The implanted portion includes an implanted coil, electronics package, and a plurality of electrodes adapted to stimulate neural tissue. The implanted coil transfers power and data to the electronics package and the electronics package drives the electrodes. The external portion includes a video processor and a pair of glasses adapted to be supported by a user's nose and ears. The glasses include a support adapted to hold an external coil in close proximity to the implanted coil when implanted; the external coil supplies power and data to the implanted coil.

Visual cortical prosthesis

Electrode arrays for biological implants are disclosed. The present disclosure provides array designs for improving apposition (reducing the space between the array and neural tissue). The present disclosure also provides electrode array designs that can be made approximately spherical to increase the field of view of a visual prosthesis while still maintaining good apposition to neural tissue.

Electrode array

The present invention is a flexible circuit electrode array for neural stimulation including a polymer base layer, a metal trace layer on the polymer base layer, and a polymer top layer on the metal traces layer, where the metal trace layer forms at least one electrode made of multiple smaller common electrodes connected by electrical traces.

Aggregate electrode for neural stimulation

Electrode arrays for biological implants are disclosed, particularly for stimulating a retina. The present disclosure provides array for improving apposition (reducing the space between the array and the retina. The present disclosure also provides electrode array designs that can be made approximately spherical to increase the field of view of a visual prosthesis while still maintaining good apposition.

Electrode arrays for a visual prosthesis

Electrode arrays for biological implants are disclosed. Electrodes are arranged in such a way so that electrical traces overlap other electrical traces in a separate layer without X shaped crossing, while overlapping to a degree sufficient to prevent dielectric breakdown of the insulating, separating layer.

Electrode arrays and their lead for use in biomedical implants

The present invention consists of an implantable device with a hermetic electronics package that houses electronics. The hermetic package is attached to a flexible circuit electrode array having its electrodes arranged in a trapezoidal electrode array field that is suitable to stimulate the visual cortex. The hermetic electronics package is provided with a fixation structure that secures, protects and dissipates heat from the electronics package. The entire implantable device can be entirely implanted within the head.
