Patent ID: 8292881

Claim:
An ablation probe, comprising: a coaxial feedline having an inner conductor, an outer conductor disposed coaxially about the inner conductor, and a dielectric disposed therebetween, wherein the inner conductor and dielectric extend beyond the outer conductor at a distal end thereof; a radiating section having a proximal end operably coupled to a distal end of the inner conductor; a distal tip coupled to a distal end of the radiating section, wherein the distal tip includes a generally cylindrical proximal tip extension having at least one o-ring disposed thereabout; a balun short disposed in electrical communication around the outer conductor and including a first notch defined therein adapted to receive an inflow tube and at least one second notch defined therein; a conductive tube disposed coaxially around the balun short; at least one fluid conduit defined longitudinally within the conductive tube, the fluid conduit including an inflow tube disposed longitudinally along the outer conductor and positioned at least partially within the first notch; and a catheter coaxially disposed around the conductive tube, wherein a distal end of the catheter is joined to a proximal end of the distal tip to define a coolant chamber therein.
