摘要：
During cryotherapy, using an endoscope that extends within a patient to a cold treatment site, the device of the invention vacuums gas from the site through radial intake ports to a cylindrical space in an evacuation chamber held elastically circumferentially about the distal end of the endoscope tube that carries the cryoprobe to the site.
