FY 2010 Performance Goals


2010 Annual Goal: Advance blind patient sight: Initiate preclinical studies of 200+ electrode implantable device. Complete specification for 1000+ pixel device.

Performance Goal/Annual Target

Quarter Quarter Goal Quarterly Results: Yes or No?
1st Quarter Design verification of subsystems for preclinical 200+ system. Goal Met. The design verification of the subsystems for the preclinical 200+ system has been completed. The thin film electrode array and the demultiplexer which were updated based on the A - 60 clinical trials have been fabricated and successfully tested.
2nd Quarter

Assembly of preclinical 200+ systems.

Goal Met. The assembly of the components including the thin film electrode array and the electronics package for a Preclinical 200+ system has been completed. Initial functional testing has verified that wireless power and telemetry was transmitted and received from the Preclinical 200+ system.
3rd Quarter Testing and verification of preclinical 200+ systems. Goal Met. A complete preclinical 200+ system was assembled and functionality was verified by the transmission of wireless power and telemetry. The electrode and lifetime parameters were characterized by immersing the preclinical 200+ system in physiological buffered saline. Preliminary results have shown electrode impedances within design parameters and accelerated lifetime greater than one year.A complete preclinical 200+ system was assembled and functionality was verified by the transmission of wireless power and telemetry.

4th Quarter

Implantation of initial preclinical 200+ systems.

Goal Met. 2 preclinical 200+ systems were surgically implanted into preclinical animal models and functionality was verified by the successful transmission of power and telemetry across the wireless link. The characteristics of more than 200 electrodes were verified to be within the design parameters after the implantation.
