Law can do so many things, sky is the limit. His power is getting cooler and cooler but it's getting harder to see how his new moves are related to medicine. You can kinda make a case for "Silent", I guess, but what would an airless room have anything to do with his power ?
It's weird that Oda is much more creative with a power so strange and hard to grasp than he is with something as simple as electromagnetism.
