摘要： 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.

摘要： 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.

摘要： A system and method for inflating and deflating a catheter balloon using osmosis. An elongate catheter shaft has a proximally disposed osmotic membrane in fluid communication with a distally mounted balloon through a fluid-filled catheter lumen. The balloon is inflated by exposing the exterior of the membrane to a solution that is hypotonic relative to the solution within the catheter lumen. The balloon is deflated by exposing the exterior of the membrane to a solution that is hypertonic in relation to the solution within the catheter lumen.
