Summary: | Improved systems and methods are used for controlled infusion of fluid into a body cavity. In particular, the improved system allows a user to accurately control pressure created in a body cavity over a broad range of fluid flow rates required in various medical procedures. In one embodiment, the system comprises a pump having a conduit which defines a fluid flow path from the pump. Typically, a surgical instrument such as a resectoscope is coupled to the conduit to direct the fluid into the body cavity. The system controls pressure in the body cavity by using a first sensor to measure pump output and a second sensor to measure body cavity pressure. Preferably, the second sensor measures the actual pressure in the body cavity to correct for any pressure losses that may occur during fluid delivery from the pump. |
