A combined isolator-diplexer device for supplying radiofrequency (RF) energy and microwave energy obtained from separate sources to a probe via a common signal pathway. The invention combines into a single unit all the necessary components to isolate a microwave channel from an RF channel whilst providing a high withstanding voltage (e.g. greater than 10 kV). The device comprises a waveguide isolator for isolating the microwave channel having a pair of DC isolation barriers arranged therein to provide a pair of series-connected capacitive structures between a ground conductor at an output of the combining circuit and a conductive input section of the waveguide isolator.

The disclosed technology is directed to a treatment tool having a blade. The blade includes a treatment surface configured to engage with a treatment target. A heater is configured to be coupled to the blade. The heater includes respective first and second heat generating surfaces each of which extending in a direction transverse to the treatment surface. Respective first and second thermally conductive members each of which is interposed between the respective first and second heat generating surfaces and the blade so as to thermally engage the respective first and second heat generating surfaces and the blade to one another. The respective first and second thermally conductive members includes respective first and second thermal conductivity anisotropies each of which being higher in longitudinal directions of the blade and each of which being lower in widthwise directions of the blade that are transverse to the longitudinal directions.

A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the first or second grasping components is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the first or second grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening therethrough. The first opening is disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed. The method comprises: using a first device to generate smoke, aerosol or vapour from a target comprising or consisting of a microbial population; mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and analysing said spectrometric data in order to analyse said microbial population.

A generator, ultrasonic device, and method of determining a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency.

Various examples disclosed relate to treatment of BPH with an integrated device for both tissue treatment and removal. The present disclosure includes a device including a sheath for partial insertion into a patient, a laser fiber actuatable for laser enucleation of tissue, an elongated member, and a tissue engagement tool on the elongated member.

Provided herein are new compositions, methods, and devices to treat cancer through a combination of immunologic chemotherapeutic agents and ablation techniques. These compositions can include immune checkpoint inhibitors, cytokines and nucleic acid drugs that aid in eliciting an immune response to treat the tumor. The administration of these compositions in addition to various ablating techniques provides a presentation of the cancer cell antigens to the immune system and the immunologic targeting of the cancer.

Surgical devices and surgical systems are disclosed. The surgical device can comprise an actuator and a control circuit configured to adjust one or more functions of the surgical device based on a signal from a situationally-aware surgical hub. A surgical system can comprise a screen and a control circuit configured to communicate a priority level of a recommendation to the clinician on the display.

Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.
