Abstract
A device and method for treating a variety of tissue locations within a patient's body using a single device that includes an elongate body having a distal portion, a shaft rotatably and slidably disposed within the elongate body, and a first arm and a second arm each coupled to the elongate body distal portion. Retraction and rotation of the shaft transitions the each arm from a linear configuration to a radially expanded configuration in which each arm has an arcuate shape and lies in a plane that is substantially orthogonal to the elongate body longitudinal axis. Electrodes coupled to the arms are equidistant from the longitudinal axis of the elongate body in different radial directions when the device is in the radially expanded configuration. The electrodes are radially symmetrical about the shaft when the radially expanded configuration has a first diameter or a second diameter.
