TWO-STAGE METHOD OF COMPRESSING A STENT

A two-stage method of compressing a stent entails providing an expandable stent (100,105) in a radially expanded state. An outward pressure is applied to an inner surface of the tubular framework to support the stent, and a diameter of the stent is reduced to a first compressed diameter (D1) while a...

Summary:A two-stage method of compressing a stent entails providing an expandable stent (100,105) in a radially expanded state. An outward pressure is applied to an inner surface of the tubular framework to support the stent, and a diameter of the stent is reduced to a first compressed diameter (D1) while applying the outward pressure. The outward pressure is halted after reaching the first compressed diameter. According to an embodiment in which the stent is balloon-expandable, a delivery balloon catheter (130) comprising an uninflated balloon in a delivery configuration is inserted into the lumen after halting the outward pressure. The diameter of the stent is reduced to a second compressed diameter (D2) smaller than the first compressed diameter to crimp the stent onto the delivery balloon catheter.
