  8. General Specifications

    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.

    Microwire Brush Array (MBA)
    • a = Length of the Microfil Tube (2.5 to 120 mm max).
    • b = Microwire contact size (determined by the selection of wire diameter).
    • c = Distance of the microwires extended beyond Microfil Tube (2 mm max).
    • n = Total # of recording wires & reference.
    • X = Diameter of the Microfil Tube (refer to the Table 1).
    • L = Length of the Flexible cable.
