1. A microwave thermal ablation system for human medical therapy to treat Barrett's esophagus, esophageal adenocarcinoma, and esophageal squamous cell carcinoma, comprising:
a microwave generator;
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 antenna mount is adjustably connected to the centering link by the expansion links, and the antenna is connected to the antenna mount;
a medical balloon inflation means; and
a positioning balloon connected to the balloon inflation means, the positioning balloon being disposed around the at least one microwave emitter 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, whereby in use target esophageal cells are destroyed by non-contact dielectric heating.
