Abstract
A flexible fluid filled actuator has an elastic bladder and a guide surrounding the bladder. The guide has asymmetrical elastic properties. When the bladder is inflated the guide directs the bladder to expand preferentially in a selected direction or directions. The actuator has utility in the traction and/or unloading of portions of the body. A fluid-filled traction apparatus is disclosed which has particular advantages in spinal unloading.
