1. An electrosurgical device for use with a source of stimulation energy and a source of ablation energy to simulate and ablate tissue under skin, the device comprising:

  • a handle having a shape permitting left handed or right handed by a user;

    a single axis probe extending from a portion of the handle capable of entering tissue at a single access point, the probe comprising at least an energy transfer section that delivers stimulation energy and ablation energy to the tissue;

    at least one stimulation switch located on a surface of the handle to permit single handed activation of the switch, where the stimulation switch is operatively connectable to the source of stimulation energy to allow the user to trigger delivery of stimulation energy to the first and second conductive portions, and to selectively increase or decrease an amount of stimulation energy through sequential depressing of the stimulation switch so that the user can deliver stimulation energy, observe a tissue response and then increase or decrease the amount of stimulation energy using a single hand;

    a tip located at a distal end of the probe, where the tip permits advancement and maneuvering of the probe under the skin and minimize a risk of puncture or cutting adjacent tissue or structures; and

    an ablation switch configured to trigger the source of ablation energy.
