A person of ordinary skill in the art, before the effective filing date of the claimed invention, would have been motivated to modify the deployable member, as disclosed by Acker, to include an acoustic barrier coupled to the deployable member, as taught by Maguire, as both references and the claimed invention are directed toward electrosurgical devices comprising expandable assemblies for delivering ultrasonic energy to ablate tissue. As disclosed by Maguire, the deployable member can include ultrasonic shields/insulators which are adapted to shield tissue from the ultrasound signal and isolate the ultrasonic coupling from the ultrasound ablation member within the balloon to a certain area of the balloon that is uninsulated ([0263] & [0312]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to modify the deployable member, as disclosed by Acker, to include an acoustic barrier coupled to the deployable member, as taught by Maguire, as such a modification would isolate the ultrasonic energy to a desired area of the deployable member and insulate non-target tissue from the ultrasound signals.
