The Future Of Organ Transplants — No Waiting!
Heart Stop Beating is a three-minute documentary film about the no-pulse, continuous-flow artificial heart, which Dan Baum writes about in our Future of Medicine issue. It tells the story of Billy Cohn & Bud Frazier, two visionary doctors from the Texas Heart Institute, who in March of 2011 successfully replaced a dying man’s heart with the device they developed, proving that life was possible without a pulse or a heart beat.
Meeko the calf stood nuzzling a pile of hay. He didn’t seem to have much appetite, and he looked a little bored. Every now and then, he glanced up, as though wondering why so many people with clipboards were standing around watching him.
Fourteen hours earlier, I’d watched doctors lift Meeko’s heart from his body and place it, still beating, in a plastic dish. He looked no worse for the experience, whisking away a fly with his tail as he nibbled, demonstrably alive—though above his head, a monitor showed a flatlined pulse. I held a stethoscope to his warm, fragrant flank and heard, instead of the deep lub-dub of a heartbeat, what sounded like a dentist’s drill or the underwater whine of an outboard motor. Something was keeping Meeko alive, but it was nothing like a heart.
The thing about growing working organs in the lab is that the whole enterprise is completely mind-blowing. Yet we just keep doing it, and so we keep blowing minds. The latest: a team of researchers at Japan’s RIKEN Center–the same group who earlier this year engineered a mouse retina that is the most complex tissue ever engineered–have now derived a working pituitary gland from mouse stem cells.
We cover biomedical science and engineering a lot, and sometimes I get to wondering: if I was rebuilding my own flimsy, flesh-based body–presumably because I’d had some ghastly dismembering, eviscerating accident–and replacing my limbs, joints, senses, and organs with the most futuristic, top-of-the-line bionics, what would I get? Would I want an artificial lower leg that sprinters use in Olympic-level races, or a motorized leg that can climb a slope as well as a natural leg? I gathered a list of 15 bionic body parts that I’d want to wear, or have installed.

Researchers in Cleveland have built an artificial lung that is so efficient it can breathe regular air rather than the pure oxygen required by current artificial lungs. The technology makes possible the idea of a man-made lung that is far more portable–and possibly implantable–for the nearly 200 million people suffering from some degree of lung disease.
California researchers have created a tissue-engineered small-scale small intestine in mice, a breakthrough for regenerative medicine and a step toward growing new intestines for humans. The process re-creates all the layers of cells that make up a functioning intestine.
Private companies and hospital researchers are increasingly making strides toward developing an artificial pancreas, supplanting insulin injections and pinpricks for patients with diabetes. Such a system would mimic the functions of a healthy pancreas, delivering insulin and monitoring blood sugar according to a computer’s careful calculations.
This ersatz lung, no bigger than a multivitamin, could represent a new pharmaceutical testing method. On it, researchers have created an artificial alveolus, one of the sacs in the lungs where oxygen crosses a membrane to enter the body’s blood vessels. A polymer sheet that stands in for the membrane is in the blue strip. On one side of the sheet, blood-vessel cells mimic a capillary wall; on the other, lung-cancer cells mimic lung epithelial cells.

You may comment in the space provided or email your thoughts to me at firstname.lastname@example.org. And – please spread the word about the immediate need for more organ donors. There is nothing you can do that is of greater importance. If you convince one person to be an organ and tissue donor you may save or positively affect over 60 lives. Some of those lives may be people you know and love.
Please view our video “Thank You From the Bottom of my Donor’s heart” on http://www.organti.org This video was produced to promote organ donation so it is free and no permission is needed for its use.
If you want to spread the word personally about organ donation, we have another PowerPoint slide show for your use free and without permission. Just go to http://www.organti.org and click on “Life Pass It On” on the left side of the screen and then just follow the directions. This is NOT a stand-alone show; it needs a presenter but is professionally produced and factually sound. If you decide to use the show I will send you a free copy of my e-book, “How to Get a Standing “O” that will help you with presentation skills. Just write to email@example.com and usually you will get a copy the same day.
Also…there is more information on this blog site about other donation/transplantation issues. Additionally we would love to have you join our Facebook group, Organ Transplant Initiative The more members we get the greater our clout with decision makers
