Abstract:
1. A microwave antenna assembly comprising: a feedline configured to deliver microwave energy to tissue, the feedline including an inner conductor, an outer conductor, and an inner insulator disposed between the inner conductor and the outer conductor; a dielectric layer formed circumferentially about at least a portion of the outer conductor; a conductive layer formed circumferentially about at least a portion of the dielectric layer, at least a portion of the conductive layer electrically coupled to a portion of the outer conductor of the feedline, wherein the dielectric layer and the conductive layer limit transmission of microwave energy in a proximal direction; and a fluid inflow tube disposed circumferentially about the feedline and defining a fluid inflow conduit between the feedline and the fluid inflow tube such that the feedline is disposed within the fluid inflow conduit.
