    Abstract: The present disclosure is directed to a medical device. Systems and methods are provided for removing particles, stone fragments and/or stone dust from a patient. The medical device described herein may work by positioning within the kidney, a catheter to flush stone dust. The catheter may include a dual lumen tube which provides fluid through one lumen to irrigate a target area and provides suction through a second lumen to carry out the irrigation fluid along with stone dust. This stone dust may be the result of a previously performed stone dusting. The irrigation fluid may be introduced with a pulsed flow. The pulsed flow irrigation may facilitate the removal of small stone fragments. The suction may be applied by a vacuum at to evacuate the target area at a flow rate balanced with the flow rate of the introduction of the irrigation fluid.
