  • Patent number: 9730634
    Abstract: An apparatus, system, and method are disclosed for mapping the location of a nerve. The apparatus includes at least one stimulation module, a stimulation detection module, a distance module, and a mapping module. The stimulation module stimulates a nerve with an electrical stimulation current from at least one stimulation electrode. A stimulation detection module detects a muscle reaction resulting from stimulation of the nerve by the at least one stimulation electrode. The distance module uses information from the at least one stimulation electrode and from the stimulation detection module to calculate a distance between the at least one stimulation electrode and the nerve. The mapping module maps a location on the nerve using at least two distances calculated by the distance module and position information of the at least one stimulation electrode for each of the at least two distances calculated.

  • Patent number: 7914350
    Abstract: An apparatus, system, and method are disclosed for creating an electrical connection with an electrically conductive element. The apparatus includes a first contact element having an engagement surface for engaging a first side of the electrically conductive element and a second contact element positioned opposite the first contact element includes an opposing engagement surface for engaging a second side of the electrically conductive element. The first contact element is slideable past the second contact element to form a scissor-like jaw. A valley formed in at least one of the engagement surface and the opposing engagement surface of the first and second contact elements creates a stage. At least one of the first and the second contact elements are made of an electrically conductive material that conducts an electrical current between the electrically conductive element and at least one of the first and second contact elements.
