1. A method of detecting if a nerve is above or below a region of a device in a tissue, the method comprising:

  • positioning a flexible elongate device within the tissue, so that an upper region of the device faces the dorsal side of a patient and a lower region of the device faces the ventral side of the patient;

    determining a threshold amount of energy required to stimulate a response in the patient while the upper region faces the dorsal side of the patient by applying increasing levels of energy from the upper region to determine the first stimulation level at which the nerve responds;

    repositioning the device within the tissue so that the lower region faces the dorsal side of the patient and the upper region faces the ventral side of the patient;

    determining a threshold amount of energy required to stimulate a response in the patient while the upper region faces the ventral side by applying increasing levels of energy from upper region to determine the first stimulation level at which the nerve responds;

    confirming that the nerve is ventral to the device by comparing the threshold amounts.
