IPC: A61B18/18
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: Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.

Abstract: A cable assembly includes a rigid portion, a flexible central portion, and a radiating portion. The rigid portion is configured to couple to a source of electrosurgical energy and to prevent fluid ingress towards the source of electrosurgical energy. The flexible central portion extends from the rigid portion and includes an inner conductor, a dielectric disposed about the inner conductor, and a conductive braid disposed about the dielectric. The radiating portion extends from the central portion and is configured to deliver electrosurgical energy to tissue.

Abstract: An energy applicator for directing energy to tissue includes a feedline having an inner conductor, an outer conductor and a dielectric material disposed therebetween, and an antenna assembly having a radiating section operably coupled to the feedline. The energy applicator also includes a first balun structure configured to substantially confine energy to the radiating section when the energy applicator is energized and disposed in tissue, and a second balun structure configured to substantially prevent energy emitted from the radiating section from propagating proximal to the second balun structure along the feedline when the energy applicator is energized but not disposed in tissue.

Abstract: A system including a catheter navigable to a location within a patient, a lumen extending through the catheter and ending at the distal end in an orifice, a fluid controller in fluid communication with the lumen of the catheter and capable of supplying a fluid to or removing a fluid from an area proximate the desired location. The control of the fluid in the area proximate the desired location affecting a dielectric constant of the area proximate the desired location. The system includes a microwave energy source, and a microwave ablation probe connected to the microwave energy source, the microwave ablation probe being navigable to a desired location within the patient. Application of energy from the microwave energy source to the microwave ablation probe in an area proximate the desired location having the affected dielectric constant results in a substantially spherical tissue effect in the area proximate the desired location.

Abstract: A system for monitoring ablation size includes a power source including a microprocessor for executing one or more control algorithms. A microwave antenna is configured to deliver microwave energy from the power source to tissue to form an ablation zone. A plurality of spaced-apart electrodes is operably disposed along a length of the microwave antenna. The plurality of spaced-apart electrodes is disposed in electrical communication with one another and each of the plurality of spaced-apart electrodes has a threshold impedance associated therewith corresponding to the radius of the ablation zone.
