A CT scan will be done during the procedure to help guide the needle which will be held in position by the study doctor(s) once it reaches the target area. With the needle(s) in place, the study doctor(s) will freeze the nerve over 5 minutes. A 3 minutes thaw will follow, then a second 5 minutes freeze and a final 3minute thaw. This portion of the procedure can last from 25 to 45 minutes. Once the nerve has been properly treated, the cryoablation needle(s) will be withdrawn.
