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.

A system for closing a blood vessel includes a housing having a proximal end and a distal end and configured to be held in the hand of a user, an elongate body extending from the distal end of the housing, a distal housing having a proximal end coupled to a distal end of the elongate body and having a cavity including an opening on a side of the distal housing, a lumen passing through the elongate body and terminating at the cavity of the distal housing and configured to couple to a vacuum source, a sensor carried by the distal housing adjacent the cavity and configured for identifying a blood vessel, wherein the lumen is configured to maintain a vacuum within the cavity when a probe having a vessel closure module is inserted within the lumen and the vessel closure module is within the cavity.

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.

A device for providing fractional treatment of a body orifice includes a source of fractionated energy and a source of electrical muscle (EMS) energy. A programmed controller controls the application of fractionated and/or EMS energy. A probe is inserted by its distal end into the body orifice. The source of fractionated energy is positioned for transmitting fractionated energy from the source of fractionated energy through the probe to tissue in the vicinity around the body orifice; and, the source of EMS is positioned for transmitting EMS energy from the source of EMS energy through the probe to tissue in the vicinity around the body orifice. The programmed controller is configured to control the activation of fractionated energy and EMS energy one of simultaneously or sequentially.

A uterine manipulator can include a shaft including a first end, a second end, and embodiments of a cutting head configured and arranged to receive a cervix. The cutting head can be configured and adapted to be used to cut the tissue joining the vaginal wall to the cervix and uterus to facilitate removal of the uterus in a minimally invasive manner.

A fluid management system for use in a tissue resection procedure includes a controller. An inflow pump is operated by the controller and configured to provide fluid inflow through a flow path to a site in patient's body. An outflow pump is operated by the controller and configured to provide fluid outflow through a flow path from the site in patient's body. A motor driven resecting device may be provided for resecting tissue at the site. The controller is configured to actuate an inflow pump and an outflow pump in response to various signals and various algorithms are provided to provide malfunction warnings and assure safe operation.

A system for closing a blood vessel includes a housing having a proximal end and a distal end and configured to be held in the hand of a user, an elongate body extending from the distal end of the housing, a distal housing having a proximal end coupled to a distal end of the elongate body and having a cavity including an opening on a side of the distal housing, a lumen passing through the elongate body and terminating at the cavity of the distal housing and configured to couple to a vacuum source, a sensor carried by the distal housing adjacent the cavity and configured for identifying a blood vessel, wherein the lumen is configured to maintain a vacuum within the cavity when a probe having a vessel closure module is inserted within the lumen and the vessel closure module is within the cavity.

A method for treating patients who suffer from chronic rhinitis that is efficient and causes fewer adverse effects than known methods. This is achieved by using a handheld surgical instrument, more particularly an electrosurgical applicator, for treatment of hypertrophic nasal conchae and/or for submucosal treatment of the posterior nasal nerve (PNN) in order to reduce at least one cardinal symptom of chronic rhinitis.

The present invention discloses a plasma operation electrode for an otolaryngology department. The plasma operation electrode for the otolaryngology department includes a tubular loop electrode, a water absorption tube and an effluent flow guiding component. The water absorption tube is sheathed in the tubular loop electrode, a water inlet channel is formed between the water absorption tube and the tubular loop electrode. An end part, away from the handle, of the tubular loop electrode is provided with at least one water outlet hole. The effluent flow guiding component is correspondingly installed at the water outlet hole, and sealed and connected on an outer wall of the tubular loop electrode. A water injecting channel is formed between the effluent flow guiding component and the tubular loop electrode. The plasma operation electrode for the otolaryngology department has a good flow guiding effect to normal saline, and high in reliability and safety.
