ABSTRACT:
A method and system for detecting damage to a balloon catheter and presence of a contaminant within the balloon catheter by irradiating a reflector located toward the distal end of the catheter tube and measuring reflectivity. By detecting a change in the reflected radiation, it is possible to identify the presence of a contaminant and the occurrence of leakage. The method and system of the present invention also permits the operator to determine deterioration of the parts of the system that detect the presence of a contaminant.
