ABSTRACT:
An apparatus and method for temporarily implanting an intraluminal stent in a body lumen and its subsequent removal. A stent is formed from a thin sheet that has been wound around itself into a generally cylindrical roll. The stent has a deployed configuration with a deployed diameter generally the size of the lumen diameter. The stent has a delivery configuration, formed by winding the stent more tightly than the deployed configuration, with the delivery diameter smaller than the deployed diameter in order to allow low profile delivery into the body lumen. The stent will transform from the delivery configuration to the deployed configuration when exposed to body heat. The stent can be deployed by an intraluminal delivery catheter that secures the stent in its delivery configuration during intraluminal delivery of the stent. The stent can be removed from the body lumen via a removal catheter that coils the stent into a sheath at the end of the removal catheter.
