Abstract: A fluid management and medical device system may include a fluid management system and a medical device. The fluid management system may include a pump configured to pump fluid to the medical device and a processing device configured to control the pump to maintain a target fluid flow range. The medical device may include an elongate shaft in fluid communication with the pump of the fluid management system, a pressure sensor, and a workstation in electronic communication with the pressure sensor and the processing device of the fluid management system. The processing device may be configured to adjust a fluid flow rate based on data received from the pressure sensor of the medical device and configured to verify the medical device is in a patient's body prior to adjusting the fluid flow rate based on the data received from the pressure sensor.

Abstract: A fluid management system may include an inflow pump configured to pump fluid from a fluid supply source to a treatment site within a patient at a flow rate; and a controller configured to operate at a target flow rate in a flow control mode. In the flow control mode, the controller may be configured to maintain the target flow rate while monitoring a measured pressure communicated to the controller from a pressure sensor. When the measured pressure reaches a preset pressure threshold, the controller may be configured to automatically switch from the flow control mode to a pressure override mode in which the controller automatically reduces the flow rate below the target flow rate to return the measured pressure at or below the preset pressure threshold.
