Swallow stent with hyperthermia function.

An operation of an esophagus cancer is one of the most difficult operations even now, when medicine progressed. One of the most important points is the difficulties of esophagus reconstruction. In an operation, since the stomach and intestines are used as a substitute, an invasion becomes large and an operation of elderly people becomes difficult. Although the improvement in a life prognosis is expected if cancer is removable, there are a lot of cases, who were too late for surgery of the esophageal cancer at the time of diagnosis. Then, a Swallow Stent with Hyperthermia function for the terminal esophageal cancer patients, for whom an operation cannot be conducted, was invented. The Swallow Stent with Hyperthermia function has three characteristics. 1. Completely noninvasive, 2. Hyperthermia on the carcinoma tissue. 3. Swallow function. Possibilities are expected as one of the alternative candidates for a terminal esophagus cancer therapy.
