Fabric Tube Propulsion Drive is a system for propelling medical devices through hollow body organs and within body cavities without causing trauma to the body surfaces upon which it operates. Fabric Tube Propulsion Drive consists of a hollow tube surrounded by a continuous loop of elastic fabric or mesh. Within the tube is a motor drive system that moves the fabric through the lumen of the tube such that the fabric on the outside of the tube can continuously interface with the body part through which the Fabric Tube Propulsion Drive is operating, and thereby drive the whole device through the body cavity or over the surface in question. Furthermore, the motor drive system can selectively apply tension to the fabric over specific areas within the tube to cause flexion of the whole tube.
