Also check out Aus patent application number 2019101517 that was accepted Dec 2019 for Ultrasonic Lumen cleaning by Saban Ventures.
The claims page indicates the innovation is around an teflon coated ultrasonic wire to clean bioburden from the inside of a lumen as it is drawn through using piezo excitation in concert with a fluid medium.

That would mean endoscope cleaning.
There is and image in the application that looks a lot like and endoscope.


There is definitely an issue to be addressed as shown by the need for testing of endoscope cleaning and storage processes.
There is also a strong requirement for record keeping.
A pretty good fit for NAN IMHO. I expect it will take some time(say 2 years) to establish in the market but the existing product success with Trophon should give them better traction than otherwise using existing customer channels and excellent reputation.
