Claim Text:
1. A cryocatheter that inserts into a vessel of a patient in a medical procedure, comprising: a catheter sheath; a catheter inner side surrounded by the catheter sheath; a catheter tip arranged at a distal end of the cryocatheter; a feed line arranged in the catheter sheath that feeds an expansion and cooling agent; a balloon arranged near the catheter tip that is expanded by the expansion and cooling agent; an imaging sensor located near the catheter tip; and an image capture device comprising the imaging sensor that maps a region of the vessel around the balloon; wherein a stent that is to be implanted in the vessel is arranged on an outside of the balloon, said stent comprising a metallic wire mesh configured to be uniformly stretched beyond an elastic limit upon the expansion of the balloon, so to retain a stretched shape against the vessel; said stent configured to retain said stretched shape subsequent to the balloon having been collapsed, based on the expansion and cooling agent being drained from the balloon; wherein the image capture device comprises an IVMRI (intravascular magnetic resonance imaging) sensor and an IVUS (intravascular ultrasonic) sensor or an OCT (optical coherence tomography) sensor and an IVUS (intravascular ultrasonic) sensor that are rotated by a drive shaft; and wherein the catheter sheath comprises a window in a region of the imaging sensor that is transparent to an imaging method used by the imaging sensor, and wherein said balloon and said stent are comprised of a material that is transparent to the imaging method used by the imaging sensor.
