    Abstract: 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.

    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: 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 resecting system includes an assembly having first and second tubular members. An electrical motor drive and controller moves the second member to resect tissue received in a window of the first member. A tachometer sends motor drive rotational signals to the controller, and the controller modulates a motor voltage in response to the signals from the tachometer both to drive the second member at a predetermined speed and to calculate resistance to driving the second member at the predetermined speed.

    Abstract: Devices, systems, and methods for resecting tissue are disclosed. In some embodiments, a tissue resecting device may comprise an elongated structure having a longitudinal axis, the elongated structure comprising an outer sleeve with a distal window configured to receive uterine polyp tissue and an inner sleeve configured to move between a proximal position and a distal position relative to the window. In some further embodiments, the device may also comprise an electrode element coupled to the inner sleeve. In some even further embodiments, the device may include an insulative layer covering at least a portion of the inner sleeve, wherein the tissue resecting device is configured to fail when used to resect tissue more fibrous than uterine polyp tissue.
