摘要
A cryocatheter for introduction into a body vessel or into an organ, with a catheter inner surrounded by a catheter sheath, and with a catheter tip arranged at its distal end, with a feed line for an expansion or cooling agent arranged in the catheter sheath or the catheter inner, and with a balloon, arranged close to the catheter tip, which can be expanded and contracted again by means of the expansion and cooling agent, is to be constructed in such a way that by simple manipulation it can be positioned at a precise target position in the body vessel and, in addition, it minimizes the burden on the patient from invasive interventions. For this purpose, in accordance with the invention an image capture device, with at least one imaging sensor for mapping the region of the vessel around the balloon, is positioned in the region of the catheter tip.
