The flexible output cable of the MBA has been designed specifically for chronic applications. The fine leads which extend from the microfil tube are coated with a silicon elastomer, allowing the tube to virtually float in the brain.
The diameter of the Microfil tube will depend on the number of wires (ie. electrode sites) and the diameter of the wires as shown in Table 1.
MicroFil™ WPI, Inc. is constructed of fused silica, coated with Polyimide.
