The cord thereof. A vision system may be incorporated into the energy delivery structure. The instrument comprise a coaxial cable conveying microwave energy therein. The dielectric tip has a dielectric constant greater than a dielectric material within the coaxial cable. The distal of the device is designed to facilitate efficient microwave energy delivery into lung tumour tissue to achieve a localized volume ablation.
