I see NOTHING about "tweaking" the device, moonie ... put your spin on it all you want, those are YOUR words, not Dr. Gurwitch's.
Hers were:
"The company had some ownership and management changes, and wasn't ready to provide us the product we had understood they would be providing. We are currently working with Valimed to identify how the product could be improved to help us enhance our current safety measures. In addition, I have been reviewing other technology improvements that could add value to the systems currently in place."
I think I might write her again and ask if TX Children's is still "currently working" with Valimed. Or maybe you'd like to. Our correspondence was in May 2007, after all. Surely she'd be candid.
