Patent ID: 8216227

Claim:
A microwave antenna assembly for applying microwave energy therapy, comprising: a proximal portion having an inner conductor, an outer conductor, a DC power and a DC neutral each extending therethrough, the inner conductor disposed within the outer conductor and the DC power and DC neutral positioned radially outward from the outer conductor; an antenna including a distal radiating section and a proximal radiating section; a junction member having a longitudinal thickness and having at least a portion that is disposed between the proximal radiating section and the distal radiating section, the junction member further including a microwave signal amplifier configured to receive a microwave signal at a first power level from the inner and outer conductor and a DC power signal from the DC power and DC neutral; and the microwave signal amplifier further configured to amplify the microwave signal from a first power level to at least one second power level greater than the first power level.
