Abstract
A device is provided for holding an appliance from an interior that may include a center support shaft, two arbors arranged on the center support shaft in a spaced apart position, a plurality of springs coupled to the two arbors, and an actuator coupled to the center support shaft and adapted to decrease the distance between the two arbors. The device may be adapted to support a hollow cylindrical object from an inside of the hollow cylindrical object. The hollow cylindrical object may include a stent. When the actuator is actuated, the plurality of springs may be compressed and each spring may buckle in at least one buckle region. Actuating the actuator may cause the plurality of springs to expand and to clamp a stent. Deactuating the actuator may cause the plurality of springs to retract and to release a stent. A system for coating a medical appliance is provided. A method for coating a medical appliance is provided.
