Patent ID: 8118808

Claim:
A surgical antenna assembly, comprising: a feedline including in coaxial arrangement an inner conductor, an outer conductor, and a dielectric disposed therebetween, the feedline having a distal end and a proximal end; a trocar screw comprising: a distal threaded section; and a cylindrical proximal section operably coupled to a distal end of the inner conductor; a dielectric puck integrally formed with the trocar screw cylindrical proximal section; an electrically conductive distal radiating section having a distal tapered end and a proximal cylindrical end; a cooling chamber defined within the distal radiating section open to the proximal end of the distal radiating section, the cooling chamber having a threaded section operably engaging the trocar screw; and a proximal radiating section having a generally cylindrical shape operably coupled to the outer conductor.
