Abstract
A balloon catheter system has a catheter with a catheter shaft surrounding a lumen. A balloon is connected to a distal end of the catheter shaft such that a fluid inflation medium can be introduced into or removed from a balloon interior via the lumen. A pressure sensor is configured to measure an instantaneous pressure (p) of the inflation medium in the lumen during inflation and/or deflation of the balloon. A flow sensor is configured to measure an instantaneous volume flow (v) of the inflation medium during the inflation and/or deflation. An evaluation unit is configured to record the instantaneous pressure and the instantaneous volume flow and to determine therefrom a time curve of the flow resistance (R).
