If NC State's athletic branches had even half the aptitude as its medical researchers, maybe then those blue boys down the road wouldn't have so much right to bang us up. Personal beefs aside, we're simultaneously stoked and amazed by a new machine crafted down in Raleigh, one that enables scientists to keep a heart pumping even after it has been removed from the body, but for research purposes only. Andrew Richards, a bright young mechanical engineering student, designed the so-called dynamic heart system, which "pumps fluid through a pig heart so that it functions in a very realistic way." Obviously, such a device has a multitude of benefits, including time / money savings compared to alternative approaches, the ability to record the inner workings of a pumping heart and scoring the creator some serious street cred in the industry. Mind-blowing video is just after the break.
OK. This isn't a classic isolated heart or Langendorf preparation as near as I can tell from the abstract available on line. The paper itself is locked away somewhere.
They are pumping blood though a heart with intact, damaged or test valves to evaluate how well they (the valves) work. The magic is in the mechanism (pump, controller etc.) that produces a life-like pressure and flow profile.
I think that's what they are doing. It would be nice if, in the interest of science, they handed out something besides a press release written by the university PR people. It would also be nice if bloggers et al did more than try to interpret a handout. Call the scientist maybe?
I'm so glad NC State is finally on Engadget. I've been waiting for one of my pack member's innovations to be posted here. No Dookies allowed, and what the hell is a tar heel anyway, Go State.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.

Unless I'm mistaken soviet era russians already did this once, although being soviets they didn't properly commercialise it, what suckers.
Getting pig-flu the hard way. (or heart way)

Yeah! Go Pack!
