Abstract
Aspiration systems and methods for controlling blood loss during thrombus removal are disclosed herein. The systems include an aspiration catheter, an aspiration tubing, a receptacle for collecting aspirated blood, a vacuum line coupled to the receptacle, and a sensor configured to measure a flow parameter associated with a liquid within an aspiration lumen. The systems further include a regulator configured to adjust a vacuum pressure within the vacuum line, and a vacuum controller operably coupled to the sensor and the regulator. The vacuum controller is configured to receive the flow parameter from the sensor, compare the flow parameter to a target range for the flow parameter, and send an automatic control signal to the regulator based on a comparison of the flow parameter to the target range. The automatic control signal causes the regulator to adjust the vacuum pressure within the vacuum line.
