Abstract
A microwave applicator for applying microwave energy to living tissue for providing uniform heating without hot spots. The applicator includes a first electrical conductor and a second electrical conductor substantially shielding the first conductor in a transmission line configuration capable of propagating microwave energy in a frequency band suitable for heating living tissue. The first conductor has an unshielded portion extending a distance beyond the second conductor and there is additionally provided a coil as a third electrical conductor surrounding the extending portion of the first conductor and connected between the ends of the first and second conductors. The applicator is preferably configured for insertion through an opening into the body and includes a substantially smooth dielectric sleeve covering the coil of the third conductor.
