Patent ID: 8655454

Claim:
A microwave ablation probe, comprising: a tubular elongated member defining a longitudinal axis and having proximal and distal ends and inner and outer surfaces, the tubular elongated member further including a plurality channels defined in the inner surface thereof; an outer conductor disposed along the longitudinal axis within the tubular elongated member; a dielectric material disposed coaxially within the outer conductor; an antenna disposed coaxially within the dielectric material, the antenna extending distally from a distal end of the outer conductor, the antenna comprising: an inner conductor disposed coaxially within the dielectric material; and a cooling sleeve disposed coaxially about a distal portion of the inner conductor having a cooling chamber defined therein; at least one inflow conduit in fluid communication with the cooling chamber and configured to deliver coolant thereto; and at least one outflow conduit in fluid communication with the cooling chamber and configured to remove coolant therefrom.
