    Abstract: A system for recording or recalling ablation information includes a workstation, and control circuitry. The workstation may include a display, a user input device, and a memory. The workstation may be configured to be in electrical communication with an ablation device. The control circuitry may be in electrical communication with the ablation device and the memory. The control circuitry may be configured to receive input associated with an ablation procedure performed by the ablation device, and associate the input with an anatomical structure of the patient.

    Abstract: A microwave ablation system includes an antenna assembly configured to deliver microwave energy from an energy source to tissue and a coolant source operably coupled to the energy source and configured to selectively provide fluid to the antenna assembly via a fluid path. The system also includes a controller operably coupled to the energy source and a piezoelectric transducer operably coupled to the fluid path to detect a force of fluid flow through the fluid path. The piezoelectric transducer is configured to generate a signal based on the detected force of fluid through the fluid path. The controller is configured to control the energy source output based on the generated signal.

    Abstract: A system for monitoring ablation size is provided and includes a power source including a microprocessor for executing at least one control algorithm. A microwave antenna is configured to deliver microwave energy from the power source to tissue to form an ablation zone. An ablation zone control module is in operative communication with memory associated with the power source. The memory includes one or more data look-up tables including one or more electrical parameter associated with the microwave antenna. The one or more electrical parameters corresponding to an ablation zone having a radius. The one or more electrical parameters include a threshold value, wherein when the threshold value is met the power source is adjusted to form an ablation zone of suitable proportion.

    Abstract: An electrosurgical ablation system includes an energy source adapted to supply energy to an energy delivery device. The energy delivery device includes a handle assembly configured to couple a pair of antennas extending from a distal end thereof to the energy source for application of energy to tissue. A power splitting device is operatively associated with the handle assembly and has an input adapted to connect to the energy source and a pair of output channels operably coupled to the respective pair of antennas. A phase shifter is operatively associated with the handle assembly and is operably coupled to the pair of output channels. The phase shifter is configured to selectively shift a phase relationship between the pair of output channels.

    Abstract: An electrosurgical system includes an energy applicator adapted to direct energy to tissue, an electrosurgical power generating source, and a surface-contact detection device. The surface-contact detection device is operably associated with the energy applicator. The surface-contact detection device is communicatively-coupled to the electrosurgical power generating source. The surface-contact detection device includes at least one optical transmitter to generate optical signals, a lens member configured to reflect optical signals generated by the optical transmitter when the lens member is disposed in contact with tissue, and at least one optical receiver to receive optical signals reflected by the lens member. The electrosurgical power generating source is adapted to transmit energy to the energy applicator when it is determined that the lens member is disposed in contact with tissue.
