Thanks for raising this issue. Here is a link to an article from a local Michigan newspaper with more information. The technology originated at University of Michigan.

Here is another link from that article to the website of HistoSonics, a firm that has been formed to develop and commercialize the histotripsy technology. It shows Johnson & Johnson and other entities with significant resources have an interest in this company. I believe U of M also has an interest in HistoSonics.
