Abstract

Abstract An apparatus for delivering energy to a surgical site from an energy source is provided. The apparatus includes; a handle, an actuator, a shaft, and a deflection wire. The actuator is movably coupled to the handle. The actuator moves from a first position to a second position. The shaft includes a proximal end, a deflectable portion and an energy delivery portion. The proximal end of the shaft is coupled to the handle. The energy delivery portion is coupled to the energy source to deliver energy to the surgical site. The deflection wire includes a proximal portion and a distal portion. The distal portion is affixed to the shaft. The proximal portion is affixed to the actuator. A movement of the actuator from the first position to the second position moves the deflection wire to produce a deflection of the deflectable portion. In an alternate embodiment of the invention a sensor and feedback control module are provided.
