摘要： Methods of crimping polymeric stents that simultaneously apply a radial force to the stent to reduce the diameter of the stent and a longitudinal force to elongate of the stent. According to one such method, a stent is inserted into an elastic tube having an inner surface that defines a passage. The tube is pulled to cause stretching of the tube. When the tube is stretched, the inner surface of the tube engages an outer surface of the stent and applies simultaneous longitudinal and radial forces to the outer surface of the stent. The simultaneously applied longitudinal and radial forces simultaneously reduce a radial extent of the stent and increase a longitudinal extent of the stent.

摘要： Methods for preparing a polymer-based stent assembly comprising an inflatable balloon catheter and a polymer-based stent resistant to relaxation-related negative recoil are provided. The methods comprise heating a polymeric cylindrical device which is at a final predetermined shape and diameter to a temperature sufficiently above the glass transition temperature (Tg) of the polymer and for a time sufficient to erase any memory of previous processing of the polymeric cylindrical device and then quenching the polymeric cylindrical device to provide an educated polymeric cylindrical device having a memory of the final predetermined diameter and shape, mounting the educated cylindrical device on an inflatable balloon catheter, reducing the diameter of the educated cylindrical device by heating to a temperature at or slightly above the Tg of the polymer while evenly applying pressure on the exterior surface of the wall of the cylindrical device, and then cooling the cylindrical device below the Tg of the polymer to provide a stent assembly comprising an inflatable balloon catheter and an expandable, educated, polymeric stent snugly and stably disposed thereon. Assemblies comprising an inflatable balloon and a polymer based stent that is substantially resistant to relaxation related recoil mounted snugly on the balloon are also provided.
