Abstract
A transcervical intrauterine catheter applicator for the hyperthermia/thermal therapy treatment of the uterus. The applicator includes one or more EMR antennas and one or more temperature sensors for measuring the temperature of the endometrial tissue. Each EMR antenna has an elongated helical coil connected to the center conductor of a coaxial cable to thereby generate a light bulb shaped radiation pattern and thus generate a similar-shaped pattern of thermal energy in the endometrium tissue. The catheter can be of the balloon type that can be inflated, thereby radially moving the antenna and temperature sensor against the walls of the uterus.
