摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A tissue resection device comprises inner and outer coaxial sleeves. The outer sleeve has a cutting window formed therein, and the inner sleeve has a distal cutting end that can be reciprocated past the cutting window. The sleeves comprise electrodes to provide electrosurgical cutting, and an edge portion of the window includes a dielectric material.

摘要： 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.
