RE: Interesting...You've probably checked out their web page where there is a lot of info on their particular product. I'm not 100% sure but I believe it's the only one that accesses the body through the sternum. Somebody correct me if I'm wrong.
From their web page:
"Developed entirely by Pyng Medical, the F.A.S.T.1TM is the world's first FDA approved adult intraosseous infusion system."
If you do a search using one of the web search engines for intraosseous infusion or something like that you'll find a lot of info on the subject.
Read the postings on the Silicon Investor chat lines for the last couple of years and you will be enlightened.
