A system includes an endoscope configured for insertion into an internal body cavity and a fluid management system. The fluid management system includes a pump configured to pump fluid through the endoscope into the internal body cavity and a controller configured to determine a pressure within the internal body cavity based upon a current feedback signal received from the pump. A method includes supplying a drive signal to a pump to pump fluid into an internal body cavity, receiving a current feedback signal from the pump, and determining a pressure within the internal body cavity based on the current feedback signal.

A vapor delivery device includes an induction coil system. The induction coil system can include a coiled fluid tube, a coiled wire, a capsule between the coiled fluid tube and the wire, and a cooling fluid supply configured to force a cooling fluid through the capsule across the coiled wire. The induction coil system can include a closed loop ferrite core, a wire coiled around a first portion of the ferrite core, and a fluid tube coiled around a second portion of the ferrite core. A wire coil can be contained in a cartridge system removably coupleable to a disposable vapor delivery device. The system can include a fluid flow controller and induction power regulation to maintain a specific operating pressure range for vapor within a uterus or other bodily cavity, tract, or duct.

A medical device for performing a surgical procedure may include an elongate member having a proximal end, a distal end, and a lumen extending therebetween. The medical device may also include a handle connected to the proximal end of the elongate member, an end effector assembly connected to the distal end of the elongate member, and a cutting device configured to extend from the end effector assembly, wherein the cutting device has a retracted configuration in which the cutting device is withdrawn into the end effector assembly and a deployed configuration in which the cutting device extends from the end effector assembly.

A hysteroscopic fluid management system includes a saline source with an electrolyte concentration, at least one pressure mechanism for circulating saline to and from a targeted site and through a filter having filter characteristics back to the source, and a controller. The controller provides a saline inflow in a first flow path to the site and a saline outflow in a second flow path from the site through the filter and back to the source at a controlled flow rate. A diagnostic or therapeutic procedure is performed at the site in the presence of the saline. The filter characteristics and the controlled flow rate are selected to (1) cause substantially no change in the electrolyte concentration in the saline, (2) to prevent hemolysis of greater than 5% of filtered red blood cells exposed to the saline, and/or (3) to minimize effect on prothrombin time of plasma exposed to the filter.

Disclosed are a system and method to implement a novel treatment to restore bilateral longitudinal parallel paraurethral support, the system comprising a trocar, and introducer, and one or more barbed suture-type devices, the components used cooperatively to implant the one or more barbed suture-type devices in the patient to provide sufficient paraurethral support to restore continence in the patient.

A visualized surgical assembly is provided, characterized in that the visualized surgical assembly includes a disposable drainage tube and a functional tube for providing visualization function, the disposable drainage tube and the functional tube are connected detachable along the axial of the tube body, and the functional tube is provided with a self-destructive part for cutting the disposable drainage tube. A corresponding endoscope is also provided. The visualized surgical assembly is a combination structure of the disposable drainage tube and the functional tube which can provide visualization function. The disposable drainage tube can removable connect with the functional tube, and the functional tube can be repeated disinfection, which can reduce the cost and avoid the risk of cross infection.

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.

A tissue resecting instrument includes a housing, a shaft rotatable relative to the housing and defining a proximal end portion disposed within the housing and a distal end portion distally-spaced from the housing, a cutting member operably associated with the distal end portion of the shaft, a turbine disposed within the housing and operably associated with the proximal end portion of the shaft, and a fluid outflow tube operably associated with the housing. The fluid outflow tube is adapted to connect to a suction source to enable the suctioning of fluid and resected tissue proximally through a lumen of the shaft, an interior of the housing, and into the fluid outflow tube. The turbine is configured such that proximal fluid flow across the plurality of fins of the turbine urges the turbine to rotate, thereby rotating the shaft relative to the housing to enable tissue resection with the cutting member.

A method of assessing inter-device communication pairing in a surgical setting, may include transmitting, by a first intelligent medical device, wireless communication data within the surgical setting, receiving, by a second intelligent medical device, the wireless communication data from the first intelligent medical device, determining, by the second intelligent medical device, communication pairing data indicative of an inter-device communication pairing of the second intelligent medical device with the first intelligent medical device, transmitting, by the second intelligent medical device, the communication pairing data to a modular control tower, and displaying, by the modular control tower on a display device, an augmented reality display comprising one or more virtual objects indicative of the inter-device communication pairing. An interactive surgical system may include multiple intelligent medical devices and displays which can form communication pairs in this manner.
