CRYOTHERAPY DEVICE AND METHOD FOR THE TREATMENT OF CERVICAL PRECANCEROUS LESIONS

摘要

A device (1) for providing a cryotherapy ablation treatment includes a piping assembly (10) and a snow horn (26) adapted to create a spray of snow from a pressurized source of a low-temperature liquid, a tubular applicator (30) for collecting a mass of snow at a prescribed density that is sufficient to allow the mass to serve as the needed, low temperature, thermal reservoir for the device (1) after the applicator's distal end (34) has been disconnected from the snow horn end so that it can to be used during the treatment process, and an applicator tip (50) adapted to allow it to connect to the applicator's distal end (34) and be used to treat those specific locations which are to receive this treatment.
