A balloon catheter including a shaft and an inflatable balloon attached to the shaft, the catheter includes an open sleeve having a proximal end sealingly attached to the catheter shaft and an open distal end. The sleeve surrounds at least part of the balloon. The sleeve and the balloon are arranged such that inflating the balloon expands the sleeve into an expanded state and deflating the balloon when the sleeve is in the expanded state forms an open cavity between the sleeve and the deflated balloon and creates suction to capture and retain debris within the cavity.
