Abstract: 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.

Abstract: 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. Thus, over a first cutting portion, radio frequency current may help cut the tissue and over a second or over transition region, the RF current may initiate vaporization of the fluid or other liquid to propel the tissue from the cutting device.

Abstract: A fluid management system for use with a fluid reservoir includes an inflow pump and an outflow pump. The inflow pump is connectable to a probe for delivering a distention fluid to a body cavity. The outflow pump removes the distention fluid through the same probe, thus establishing a re-circulating volume of distention fluid within the body cavity. The removed fluid is filtered and returned to a fluid reservoir for eventual recycling to the body cavity. A controller adjusts the flow rates of the inflow pump and the outflow pump to maintain a pre-selected fluid pressure or volume within the body cavity.

Abstract: Systems, devices, and methods for fluid management in an endoscopic procedure are disclosed. In one embodiment, a fluid management device may comprise a pair of electrodes and a controller connected to the pair of electrodes. In at least some embodiments, the controller may be configured to receive signals from the pair of electrodes and determine whether a fluid in a fluid reservoir is an ionic fluid or a non-ionic fluid based on signals received from the pair of electrodes. In at least some additional embodiments, the controller may be further configured to automatically set a fluid deficit alarm threshold based on the determination of whether the fluid in the fluid reservoir is an ionic fluid or a non-ionic fluid.

Abstract: A tissue cutting device has an outer sleeve with a distal window and an inner cutting sleeve which moves past the window to cut tissue. The inner cutting sleeve has a lumen which may have a larger proximal diameter than distal diameter. A perimeter of the window may comprise a dielectric material. A distal edge of the inner sleeve may be displaced inwardly.

Abstract: 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.
