Method of fabricating an integrated intraocular retinal prosthesis device
First Claim
1. A method of fabricating an integrated intraocular retinal prosthesis device having an electrode array region, a power and data management region and a cable region connecting the electrode region with the power and data management region, the method comprising:
- forming a patterned layer of conductive material on a first layer of polymer material, said patterned conductive layer defining circuit elements of the power and data management region, the electrode region and the cable region wherein the circuit elements of the power and data management region include one or more RF coil elements formed of the conductive material;
covering the patterned conductive layer with a second polymer layer; and
removing a portion of the second polymer layer in the electrode array region so as to expose at least a portion of the patterned conductive layer to form an exposed electrode array.

Abstract
Intraocular retinal prosthesis devices and methods for fabricating the same. A prosthesis device includes a cable region that connects an electrode array region with a power and data management region. The electrode array region includes one or more arrays of exposed electrodes, and the power and data management region includes various power and control elements. The power and data management elements, in one aspect, include an RF coil or coils and circuit arrangements and/or chips configured to provide drive signals to the electrodes via a cable and receive power and signals from the RF coil or coils. Each region includes elements fabricated on or in a single polymer layer during the same fabrication process.
