1. A method for repair or refurbishment of limited use medical devices comprising the steps of:
- providing a disabled limited-use electrically powered medical device, the medical device comprising a plug attaching and electrically connecting the medical device with a power source, the plug comprising;
a sheath,a protective element encompassing wires,a hub abutting the protective element,a circuit board comprising a electrical control system and positioned adjacent to a surface of the hub opposite the protective element,a plurality of pins protruding from a surface of the circuit board, anda shield surrounding a portion of the hub and circuit board;
inserting a supplemental circuit board into the plug, the supplemental circuit board comprises a supplemental electrical control system; and
electrically connecting the supplemental circuit board to at least one of the plurality of pins;
wherein the supplemental electrical control system of the supplemental circuit board is functionally equivalent to the electrical control system of the medical device, andwherein the supplemental electrical control system functionally replaces the electrical control system of the medical device.

Abstract
A powered medical device includes electronic components on a circuit board embedded within the body of a plug for connecting the device with a control apparatus. The medical device may be repaired or refurbished without the need to access the embedded circuit board through the use of a supplemental circuit board installed into the open end of the plug adjacent the plug pins. The supplemental circuit board may include a variety of electronic components, including fuses or non-volatile memory.
