摘要: A cryocatheter for treating cardiac arrhythmias comprises a miniature refrigeration system powered by electromagnetic radiation. The is disposed at the tip of catheter and radiation delivered to waveguide. includes an engine that converts into mechanical work. compresses refrigerant circulation through microchannels in system. Such compression achieved using superheat portion liquid mass. superheating causes explosive boiling propel mass compress refrigerant. While particularly advantageous system, may also be applied other types devices.
