Abstract
Medical devices, methods and systems for treating tissue are provided. An exemplary system comprises a fluid from a fluid from a fluid source at a fluid flow rate, a surgical device which provides power and the fluid to the tissue and a control mechanism which changes a fluid flow rate provided from the surgical device and changes a power level provided from the surgical device. The fluid flow rate changes between at least two-zero flow rates and the power level changes between at least two non-zero levels. An exemplary method comprises providing a fluid from a fluid source at a fluid flow rate, providing a surgical device which provides power and the fluid to the tissue, and changing the fluid flow rate of fluid provided from the surgical device with a change in power level provided from the surgical device.
