Abstract: Improved-coverage RF neurotomy instrumentation includes an introducer used to deploy a set of electrodes to an area to be treated. The introducer features a plurality of elongated, co-extensive cannula, each including an insulated, electrically conductive electrode. Each electrode has a proximal end configured for attachment to a source of energy, and an exposed distal tip to deliver the energy to a localized region, and each electrode slides within its respective cannula so as to enhance the energy coverage area.
