Having worked a fair amount with ultrasound for eye surgery [0] the physics similarities are very striking (the FEA simulation gave me flashbacks) but it's almost funny how the same principles can be translated and applied for an entirely different end purpose (cataract surgery, and slicing tomatoes!) To use Scott's words it is very cool to see such a tech translation from industry to home use. I would still be cautious about the lifetime of these devices (namely how it will deal with water ingress over time) but the fact that they will come out of a factory is already quite a HW startup feat.
