Abstract:
1. A microwave ablation probe, comprising: an elongated shaft defining a longitudinal axis and having proximal and distal ends; an outer conductor disposed along the longitudinal axis within the elongated shaft; a dielectric material disposed coaxially within the outer conductor; an antenna disposed coaxially within the dielectric material and movable between a proximal non-deployed position wherein the antenna is substantially within the outer conductor, and a distal deployed position wherein the antenna extends distally from the outer conductor, the antenna comprising: an inner conductor disposed coaxially within the dielectric material; and a cooling sleeve disposed coaxially about a the 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.
