Microwave Ablation with Triaxial Antennas Tuned for Lung: Results in an in Vivo Porcine Model

Abstract

A 17-gauge triaxial microwave ablation system tuned for lung tissue yielded large circular zones of coagulation in vivo in porcine lungs. The coagulation zones created with bronchial occlusion and multiple antennas were significantly larger than those created with one antenna.
