Abstract:
A nerve stimulator needle apparatus comprising:a needle capable of carrying an electric current; a variable control mechanism which is operable to variably control the amplitude of an application of electric current to said needle during a procedure using said needle; a plurality of electrical connectors connected to said variable control mechanism and said needle which allows said variable control mechanism to remotely connect to a nerve stimulation device which is operable to provide a voltage to said variable control mechanism and to provide a current pulse to said needle having an amplitude which is controlled by said variable control mechanism; and a housing which holds said variable control mechanism, said plurality of electrical connectors and said needle, wherein an electrically resistive layer covers said needle, the resistance of said resistive layer changes with the length of said resistive layer, and an electrical trace from an electrical pin connector provides a voltage to said electrically resistive layer from said nerve stimulator device.
