System and method for performing an electrosurgical procedure using an ablation device with an integrated imaging device

Abstract

An ablation device includes an antenna assembly having a radiating portion configured to deliver energy from a power source to tissue. The radiating portion has an outer conductor and an inner conductor. The inner conductor is disposed within the outer conductor. The device also includes an imaging device operably coupled to the radiating portion. The imaging device is configured to generate imaging data corresponding to tissue proximate the radiating portion of the antenna assembly.
