It looks like she already took the deal, or at least some variation of it - http://artuitive.com/recent.html
Hopefully, she is able to negotiable a more favourable deal for herself and have better control on the startup she created. The original deal as stated in the NYTimes articles is pretty crappy.
If she maintains control, then sure - that might work, depending on how large amounts of sale she can gain from this move. But 25% doesn't smell like control to me.
