A surgical fluid management system delivers fluid for distending a uterine cavity to allow cutting and extraction of uterine fibroid tissue, polyps and other abnormal uterine tissue. The system comprises a fluid source, fluid deliver lines, one or more pumps, and a filter for re-circulating the distension fluid between the source and the uterine cavity. A controller can monitor fluid retention by the patient.

A system for accessing a patient's uterine cavity and detecting perforations in the uterus includes an elongated probe having a flow channel extending to a terminal outlet in a distal region of the probe. A fluid source is coupled to the flow channel, and a seal on the probe is positionable in an endocervical canal. The probe may be trans-cervically inserted into the uterine cavity, and a fluid may be introduced through the channel to flow outwardly from the terminal outlet into the uterine cavity. A parameter of said fluid flow is monitored to detect a perforation in the uterus.

A cartridge for delivery of a material therefrom which has a corrugated portion to allow for bending/extending to be applied to the device from which a material to be deposited can be dispensed. The bendability and extendibility allow for greater efficiency in use and application of the material into cavities, pockets, and/or crevices where one needs to deposit the material.

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 and apparatus for assessing bodily cavities and lumens utilizing an integrated, automated aerating device is described. The aeration device can selectively supply a gas a liquid during ultrasound and radiographic procedures for enhanced visualization of the uterine cavity and fallopian tubes.

There is provided a cervical canal dilator device having a hollow shaft having proximal and distal ends. The shaft is covered on an end portion of the distal end by a slidable protective sleeve. There is at least one inflatable dilating balloon formed on the distal end of the shaft. There is at least one tube extending internally along the shaft and connected to the at least one balloon for inflation thereof, the tube having a connection port on the proximal end of the shaft. A camera is situated at the tip of the distal end of the shaft and a plurality of ejection orifices are formed on the shaft, adjacent to the camera, and anywhere else along it. The shaft is inserted into a patient's cervical canal while viewing the canal via the camera for guidance, and safe and easy placement of the hollow shaft during the insertion, and where the at least one balloon is inflated by introducing a substance via the connection port, the inflated balloon causing dilation of the cervical canal, the shaft being removed from the patient when the cervical canal is dilated.

A method for operating a fluid management system includes automatically detecting an unstable condition in the system, which may include detecting a large change in the supply fluid amount (indicative of a bag change), detecting a large change in the waste fluid amount (indicative of a bag change), or detecting a large difference between the amount of fluid dispensed as measured by the weight data and the amount of fluid dispensed as measured by the flow data (indicative of a blockage in the supply tubing). The method further includes adjusting the operating mode of the system during the unstable condition, which may include switching to using flow data rather than weight data to track the fluid deficit during a supply bag exchange, halting operation of an outflow pump during a waste container exchange, and/or halting operation of the system during a blockage in the supply tubing.

A system, apparatus, and method for delivering a drug into a target volume of a subject includes an ultrasound scanner for performing a volume scan of a predetermined volume of the subject, a computing device for generating a 3D model of the predetermined volume and computing navigational data to reach the target volume from an entry orifice of the volume of the subject, a housing, for accommodating a barrel, to which a sheath is detachably attached, and a drug delivery device for delivering the drug at one or more locations in the target volume, wherein the drug delivery device is configured for delivering a predetermined volume of drug at one or more locations in the target volume of the subject.

Surgical drains may include a tube, a drainage component, and an positioning mechanism positioned between them. The positioning mechanism may include a shaft configured to encircle a junction between the tube and the drainage component and a plurality of extensions that extend from the shaft. The drainage component may have a plurality of holes sized and configured to allow fluid, solids, and/or gas to pass therethrough, enter a lumen of the drainage component, and be communicated to a lumen of the tube for evacuation from a hollow organ and/or tissue in which the surgical drain is placed. On some occasions, the surgical drain may be placed within a uterine cavity via a hysterotomy following pelvic surgery and may be used to evacuate blood and other fluids from the uterine cavity and/or contract the uterus following caesarian delivery of a fetus.
