RAPID ELECTRODE DEPLOYMENT

摘要

An apparatus for ablating tissue has an elongate member, at least two electrodes housed within an axial lumen of the elongate member, and an electrode actuator for advancing the electrodes beyond a distal end of the elongate member and into tissue to a site targeted for ablation. The electrode actuator rapidly advances the electrodes beyond the distal end of the elongate member so that the electrodes assume a uniform outwardly everted configuration.
