Suspension Tank

video|right|300px right|300pxA Suspension Tank is a large tank that is used in treating severe injuries where a patient is near death. It creates a womb like environment in which they are able to do nothing except heal the body. The patient is often placed in an artificial coma.
The tanks are also used in cloning, usually body parts or organs needed for surgery, but in less reputable areas of the galaxy they can be used for cloning.
