1. A fluid management system comprising:
- a cartridge having a plurality of fluid channels, including first, second, third and fourth fluid channels defining a three-dimensional fluid path for fluid flowing therethrough, said cartridge having a main wall dividing the cartridge between first and second sides, whereinthe first fluid channel and the fourth fluid channel are separated by a first separation wall and are located on the first side of the cartridge,the second fluid channel and the third fluid channel are separated by a second separation wall and are located on the second side of the cartridge,said cartridge includes an inlet in fluid communication with said first fluid channel and an outlet in fluid communication with said fourth fluid channel, andsaid fluid flowing through the three-dimensional fluid path of the cartridge from the inlet to the outlet in order of;
first fluid channel, second fluid channel, third fluid channel, and fourth fluid channel;
a heater assembly including;
a housing having a slot dimensioned to receive the cartridge,a plurality of infrared lamps, including first, second, third and fourth infrared lamps mounted within the housing generally adjacent to the slot, whereinthe first and fourth infrared lamps are respectively located proximate to the first and fourth fluid channels on the first side of the cartridge when received in the slot, andthe second and third infrared lamps are respectively located proximate to the second and third fluid channels on the second side of the cartridge when said cartridge is received in the slot; and
a control system operatively connected to the plurality of infrared lamps to adjust power to the plurality of infrared lamps to heat the fluid in the three-dimensional fluid path to a desired temperature.

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.
