Abstract:
1. An ablation device, comprising: a feedline including an inner conductor having a distal end, an outer conductor coaxially-disposed around the inner conductor and having a distal end, and a dielectric material disposed therebetween; and an antenna assembly including: an electrically-conductive proximal arm having a proximal end and a distal end, the proximal end electrically coupled to and coaxially-disposed about the distal end of the outer conductor; an electrically-conductive distal arm including a proximal portion having an outer diameter and a distal portion having an outer diameter less than the outer diameter of the proximal portion; and a junction member, wherein the electrically conductive proximal arm and the electrically-conductive distal arm align at the junction member and are spaced apart a length by the junction member, thereby defining a feed gap therebetween.
