摘要:
A cryotherapy catheter can include an elongate member and an inflatable balloon portion at a distal end of the elongate member. The inflatable balloon portion can have an external surface and an interior chamber, and the external surface can include a cooling region and a thermally insulated region. The interior chamber can be configured to receive during a cryotherapy procedure a cryogenic agent for extracting heat from body tissue that is in contact with the cooling region. A thermal profiling component can be disposed in the interior chamber and configured to thermally insulate the thermally insulated region from the cryogenic agent to minimize heat extraction by the cryogenic agent from body tissue that is in contact with the thermally insulated region.
