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 is movable relative to the needle, and as the coil is deployed it attains a coiled configuration and a twisted configuration. After 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.
