Abstract

A stent loading device may comprise a stent crimping device, a fluid source and a support device arranged to support and move a stent delivery device. The fluid source may provide chilled fluid capable of placing a shape memory material into a martensitic state. After stent crimping, as the crimping device opens, the fluid flow may advance at least a portion of the stent into the delivery device. A step procedure may be used to move the rest of the stent into the delivery device, wherein the delivery device may be moved away from the crimping device, the portion of the stent still in the crimping device may be crimped again, and the delivery device may be moved back to its original position, thereby stepping another portion of the stent into the delivery device. The step procedure may be repeated until the entire stent is oriented within the delivery device.
