Abstract
An apparatus for coupling a percutaneous electrode to an electrical power source, and methods for operating such an apparatus. In one embodiment, the apparatus can include a housing, an electrode movably coupled to the housing and having a sharpened end to pierce a skin surface, and an actuator releasably coupled to the electrode to move the electrode relative to the housing. The actuator is movable relative to the electrode between a first position and a second position. The actuator has a conductive member coupleable to a source of electrical power, and the conductive member has a first surface and a conductive feature with a second surface offset from the first surface. The conductive member is releasably engaged with the electrode when the actuator is moved to the second position and can provide mechanical feedback to the operator when the conductive member engages the electrode.
