In honor of Dr. Who

Granted, they are only levitating the disk when in water, but the Dundee scientists are also making that rubber disk rotate using shaped ultrasonic pulses (with 1000 transducers!). With appropriate beaming, you could "massage" small organs inside a body without cutting it open.

Tissue near the focus would also tend to be "massaged", though not as strongly, and there might be bruising--but that might worth it when trying to shove bone fragments back into place.

A pity it won't be any good for loosening recalcitrant screws...
