Claim 14:
15. A microwave thermal ablation system for use in treating Barrett's Esophageal cells, esophageal adenocarcinoma, and esophageal squamous cell carcinoma via non-contact dielectric heating, comprising:
a. a microwave generator for providing 915 MHz to 20 GHz microwave energy;
b. a microwave emitter communicatively connected to the microwave generator, the microwave emitter being adapted to being inserted into the esophagus of a patient, the microwave emitter including:
a centering link,
an antenna mount,
a pair of expansion links, and
an antenna,
whereby the centering link is adjustably connected to the antenna mount by the expansion links, and the antenna is connected to the antenna mount;
c. a medical balloon inflation means;
d. a positioning balloon connected to the balloon inflation means; the positioning balloon being disposed around the microwave emitter and adapted to create a deterministic circular lumen of a known diameter inside the esophagus of a patient and to hold the microwave emitter in a desired position relative to and spaced apart from a target tissue or tissues within the esophagus of a patient, the positioning balloon being disposed around the microwave emitter, whereby, in use, target esophageal cells are destroyed by non-contact dielectric heating; and
e. a catheter shaft including:
(i) at least one power line electrically connecting the microwave generator and the microwave emitter, and
(ii) at least one lumen communicatively fluidly connecting the balloon inflation means and the positioning balloon,, the microwave emitter and the positioning balloon being coupled to the catheter shaft at a predetermined position, the catheter shaft being adapted to being inserted into the esophagus of a patient and for translating the at least one microwave emitter and the positioning balloon within and through the patient's esophagus.
