Title: ELECTROSURGICAL INSTRUMENT
Abstract:
An electrosurgical instrument includes a needle configured as a first electrode and a coil extending through the needle and configured as a second electrode. The coil movable relative to the needle, and as the needle and the coil are inserted into tissue and energized with an electrical energy source, the needle and the coil apply current to the tissue to coagulate the tissue. The coil includes a fluid transmission feature that allows a fluid to flow distally for cooling the coil.
