A colpotomy system includes an energy source and a uterine manipulator that is electrically coupled to the energy source. The uterine manipulator supports a colpotomy cup and extends to a conductive distal tip portion. The colpotomy cup includes a conductive surface. One or both of the conductive distal tip portion and the conductive surface of the colpotomy cup are configured to return monopolar energy to the energy source.

The present invention discloses access devices and methods to create an access channel for introduction of one or more working devices into an anatomical region. The access channel is created using a visualization modality that is later removed before inserting one or more working devices through the access channel. This allows the methods and devices of the present invention to be used even in small sized natural or surgically created insertion tracts leading to the anatomical region. The access channel can be made of a device such as a sheath, a guidewire, and an elongate device comprising a lumen. Examples of visualization modalities are endoscopes and body insertable ultrasound imaging devices. The working devices can be used to perform a variety of diagnostic, therapeutic, or preventive procedures. Endometrial ablation devices and procedures have been used as an example to describe various aspects of the present invention.

An ultrasound device includes an ultrasound body having a shaft and an ultrasound sensor assembly disposed at a distal end portion of the shaft. The ultrasound sensor assembly is configured to enable ultrasound imaging. A clip is configured for positioning about a portion of a surgical tool. The clip is configured to releasably engage the ultrasound body to thereby releasably couple the surgical tool with the ultrasound body. A surgical system includes the ultrasound device and the surgical tool.

The present invention relates to a medical device for generating a plasma-activated liquid, a system for generating plasma-activated liquids comprising said device, and a method for generating a plasma-activated liquid. It also relates to a method for prophylaxis and treatment of postoperative adhesions.

Apparatus for delivering a therapeutic agent to a uterine cavity including an elongated member having a fluid channel for passage of the therapeutic agent into the uterine cavity, a dispensing member extending distally of the elongated member and having at least one perforation for passage of the therapeutic agent into the uterine cavity into contact with the endometrium. An infusion line is in communication with the fluid channel for passage of a fluid into the uterine cavity to assess leakage to determine integrity of the uterine cavity prior to passage of the therapeutic agent into the uterine cavity.

An exhaust collection bag for cryogenic treatment is described herein and may generally comprise a first layer and a second layer attached along a periphery and forming an enclosed volume. The periphery defines four radiused corners and an extension member. A tubing connector may be positioned along the first layer and extend through the first layer and may also be located along a centerline of the first layer and in proximity to a bottom edge of the first layer. A drain closure may also be positioned along the first layer and located away from the centerline and in proximity to the bottom edge.

Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool.

A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

Systems and devices for resecting and removing tissue or organs from the interior of a patient's body, in a minimally invasive laparoscopic procedure while preventing any dispersion of potentially malignant tissue during the resection process.

An electrosurgical device includes an elongated shaft, an active electrode, and a return electrode. The elongated shaft has an end effector that is operably engaged with a distal portion thereof and a channel defined therethrough. The distal portion of the elongated shaft includes a distal tip that is configured to provide suction from a suction surface to the distal tip through the channel. The end effector may include a flare a proximal end thereof. The active electrode is positioned adjacent the distal tip of the elongated shaft and is configured to deliver electrosurgical energy to tissue. The return electrode is positioned on an outer surface of the end effector proximal of the active electrode. The return electrode is configured to provide a return path for the electrosurgical energy.
