| Zusammenfassung: | An aspiration catheter is provided in which vacuum may be accumulated within the catheter and released suddenly within a distal region of the catheter to induce ingestion of intravascular matter into the catheter through an open 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. |
