Abstract
A balloon catheter system includes a balloon extending in an axial direction. A stent is crimped onto an outer surface of the balloon. A catheter is connected to the balloon and includes a lumen in fluid communication with a balloon interior of the balloon. At least one sensor associated with the balloon measures expansion of the balloon in a radial direction (R). A processing unit receives a signal from the at least one sensor and is connected to terminate filling of the balloon interior with a fluid medium (M) and/or to prompt a display device to output a display if the signal reaches a threshold value above a predefined reference value, the signal being indicative of a current diameter (D) of the balloon in the radial direction (R), the reference value corresponding to a balloon diameter upon contact of a proximal and/or distal balloon end with a vessel wall, and the threshold value exceeding the reference value by 5% to 20%.
