摘要： The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.

摘要： 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.

摘要： A probe for resecting and coagulating tissue comprises an outer sleeve having a tissue cutting window and an inner sleeve having a tissue cutting distal end. And RF cutting region is formed at the distal end of the inner member and an RF coagulation region is formed on an exterior surface of the inner member immediately proximal to the cutting surface. A single power supply providing a single RF energy mode can be connected to both RF applicator regions to simultaneously cut and coagulate tissue.

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.
