I don't know if a buyout would be in the cards; but I know there's been a hint about a minority investment from a partner in the June 16th press release:
"In order to have the option to utilize the complete SBI financing, and/or the potential sell equity to one or more strategic partners with whom Biophan is in discussions, the Company will present to its shareholders the approval to authorize additional shares."
I think a minority investment from BSX is more likely than a buy out. I think Biophan could liscense its technology to a wider range of medical device companies as a stand alone business. Where as if BSX owned the technology, they would probably want to keep it exclusive.
