PLAQUE STABILISATION USING CRYOENERGY

摘要

There is provided a method of supplying cryoenergy to a plaque within a blood vessel. The method comprises expanding an expandable membrane of a catheter apparatus with a pressure of less than 5 ATM (507 kPa), the catheter apparatus having been placed in thermal contact with the plaque within the blood vessel. The method also comprises establishing a temperature of between +15° C. (288K) and −35° C. (238K) at an interface of the expandable membrane and the blood vessel. A system and catheter apparatus are also provided.
