Abstract
A balloon type catheter or endotracheal tube is provided that can be inflated with a high pressure along part of its length so that it may be stiffened for easy insertion into the body. When in place in the body the air pressure can be released making the tube much more flexible but resistant to kinking due to a spiral wound plastic tube in the wall.
