Abstract: An electromagnetic surgical ablation system having a generator adapted to selectively provide surgical ablation energy to an ablation probe, and methods of operating same, are disclosed. The system includes a controller operatively coupled to the generator, and a tissue sensor probe operatively coupled to the controller. The tissue sensor provides a tissue temperature and at least one tissue dielectric property to the controller. During an electromagnetic tissue ablation procedure, the controller monitors tissue temperature and the at least one tissue dielectric property to determine tissue status, and to activate and deactivate the generator in accordance therewith.

Abstract: A surgical probe includes a connection hub, an antenna assembly, and an outer jacket. The antenna assembly is coupled to the connection hub, extends distally from the connection hub, and includes a radiating portion coupled thereto at the distal end thereof. The radiating portion is configured to deliver energy to tissue to treat tissue. The outer jacket is coupled to the connection hub, extends distally therefrom, and is disposed about the radiating portion. The outer jacket includes a distal end member configured to be spaced-apart from the radiating portion a target axial distance. One or more of the couplings between the antenna assembly and the connection hub, the radiating portion and the antenna assembly, and the outer jacket and the connection hub defines a flexible configuration permitting axial movement therebetween to maintain the target axial distance between the radiating portion and the distal end member.

Abstract: A method of generating a representation of an active heating zone on a display in real time during an ablation procedure includes processing imaging data of a surgical site generated by an imaging device, navigating an ablation device in proximity to target tissue, delivering electrosurgical energy to the target tissue via the ablation device to generate an active heating zone, detecting a Doppler shift in the imaging data based on the delivery of electrosurgical energy to the target tissue, and generating a representation of the active heating zone relative to the surgical site based on the detected Doppler shift.
