Abstract
Surgical fluid management systems and methods of operating surgical fluid management systems which may provide one or more functions associated with suction, irrigation, distention, deficit monitoring, infusion, fluid warming, and the like. Some example embodiments may include infra-red lamps arranged to heat fluid flowing through a disposable cartridge. Some example embodiments may provide a three-dimensional fluid path through the cartridge and/or multi-stage heating capabilities. Some example fluid management systems may be selectable between pressure control and flow control modes.
