1. A catheter for detecting diseased tissue in a hollow body organ, the catheter comprising:

  • a. an elongated tubular catheter shaft having a proximal end which remains outside of the body organ when in use and a distal end which is inserted into the body organ when in use, the distal end having a light transmission zone through which light can be transmitted;

    b. a fiber lumen in the catheter shaft for containing a diagnostic optical fiber having a distal end terminating within the light transmission zone for emitting and receiving diagnostic light through the light transmission zone;

    c. a diagnostic subassembly at the proximal end and in communication with the diagnostic optical fiber for processing diagnostic light for use in connection with a diagnostic method for detecting diseased tissue;

    d. an occlusion balloon positioned on the distal end of the catheter shaft adjacent to the light transmission zone;

    e. an inflation lumen in the catheter shaft and in fluid communication with the balloon for delivering fluid from an inflation fluid source at the proximal end of the catheter shaft to the balloon;

    f. an infusion lumen in the catheter shaft for delivering infusion fluid from an infusion fluid source at the proximal end of the catheter shaft to the distal end of the catheter shaft; and

    g. one or more infusion ports formed on or near the light transmission zone and in fluid communication with the infusion lumen for delivering infusion fluid to the hollow body organ.
