摘要:
A method for determining a sufficient stent removal force includes providing a balloon fastened to a shaft with a stent securely clamped to the balloon. In order to move or remove the balloon from the stent, a stent removal force has to act on the balloon in the axial direction. The stent, which surrounds the balloon, is clamped between first and second holding jaws with a predefined contact pressure perpendicularly to the axial direction. A predefined, desired stent removal force is then exerted on the balloon via the shaft in the axial direction, at which the balloon should not be removed from the stent. If the balloon moves axially relative to the stent, the force is considered to be too low and the shaft-balloon-stent assembly is discarded as a reject. If the stent position remains constant, the stent removal force is considered to be sufficient.
