ABSTRACT:
The present invention is directed to a proximal catheter assembly that is configured to facilitate aspiration through a catheter lumen. The proximal catheter assembly enables natural aspiration to be achieved within the catheter lumen, for example, using an arterial-venous shunt, and further enables suction-assisted aspiration or infusion to be applied through the catheter lumen. This allows a physician to provide a substantially continuous level of retrograde flow within a vessel during a medical procedure without damaging the vessel wall, while providing the option of suction-assisted aspiration, when necessary, to further influence the level of aspiration within the vessel.
