Abstract: A fluid management system may include a fluid pump capable of generating a pulsatile flow of fluid, a fluid pathway for transporting the pulsatile flow of fluid from a fluid source through the fluid pump to a medical device, a dampening element in fluid communication with the fluid pathway and operably independent of the fluid pump, the dampening element comprising one or more barrels, each barrel including a movable seal member disposed within the barrel and a biasing member disposed within the barrel and engaged with the movable seal member, the dampening element being responsive to pressure fluctuations of the pulsatile fluid flow to actively dampen the pressure fluctuations, and a fluid flow sensor disposed along the fluid pathway between the dampening element and the medical device to measure a flow rate of the smoothened pulsatile fluid flow in both flow directions.
