Abstract

The invention concerns a method and a device for crimping a stent onto a balloon of a balloon catheter. The stent is arranged on the balloon so that an outside surface of the balloon and an inside surface of the stent contact each other to form a combination of balloon and stent. The combination is compressed to crimp the stent onto the balloon. The invention is distinguished in that the combination is compressed to varying degrees along the longitudinal axis of the combination.
