Abstract
An aspiration catheter is provided in which rapid withdrawal of a piston disposed within a distal region of a catheter lumen creates a sudden pressure drop for ingestion of intravascular matter into the catheter lumen through a distal port while avoiding large losses of suction common with catheters having long aspiration lumens. Conventional aspiration using the same catheter can subsequently complement the procedure by fully removing the ingested matter from the catheter.
