FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to surgery. Cryoexposure is performed on granulation tissue around radial part of endobronchial valves in cryodevitalisation mode. Several cycles are carried out successively, in each of which the granulation tissue is frozen for 20 s to a temperature of −80 °C subsequent thawing. Then the endobronchial valve is pulled and separated.
EFFECT: method enables simplifying and accelerating the process of removing endobronchial valves, reducing the level of low-temperature exposure.
