Transcript for Deep Freeze in Medicine at the Cryonics Institute
In medical news tonight the deep freeze this is primarily about the quest for a second life. And ancient gold which scientists are always pursuing we've been looking into the future of medicine where the unbelievable is becoming at least remotely possible. Such as freezing the dead in order to raise them. Here's ABC's Kevin Newman with Madison. On the cutting edge. This ambulance is designed for someone who's already dead. The urgency is to limit the damage dying guts to the brain and the body so that someone some day might reverse it. Ninety people in America are frozen hoping to come back to life when medicine can cure them many of them are new cases in the past three years. To the handful of companies that charge from 28000. Dollars to freeze them these are optimistically called patients. When did you get your most recent patient. Today is Thursday are our most recent patient came -- this last Saturday. She was or is a ninety year old woman who suffered a heart attack and it was now inside this box cooling to minus forty degrees. With the help of rice and chemicals injected to minimize damage. After a week she's going to be moved into this chamber and cooled with liquid nitrogen to. Minus 310. Degrees. The week after that she'll join the others inside these sealed vacuum chambers. How many people would be in this largest chamber largest chamber as fourteen stations. However even with the precautions. Ice crystals formed during the freezing that injure the brain and -- A problem researches reducing. There's been gradual process and we haven't had any dramatic breakthrough but we are constantly improving. If people are being frozen with less damage there's still the problem of how do you bring them back to life and in thirty years nobody's found the answer. But now some scientists think they may have won. -- technology is the ability to build microscopic size machines with atoms and molecules which some scientists believe. Could repay -- freezing damaged. We could have fleets of small computer controlled devices that could be injected. That would circulate throughout the body in which would identify and correct problems. Suddenly there's an idea of how bodies already frozen can be repaired if there ever thought -- Which is also reassuring to those contemplating -- process who wonder when they'll be able to come back. I'm much more confident now but we're confident that this will be a reality in the near future. I was in the past -- thinking you know 34500. Years now and looking to 305070. Years from now. So like so much else in medicine cry on -- once considered on the outer edge is moving closer to reality. Which means a lady -- here may have a future after all.
