摘要：
A neurovascular aspiration catheter has an elliptical distal aspiration port. The catheter has an elongate flexible tubular body comprising a distal port and a side wall defining a central lumen in communication with the port. A tubular radiopaque marker is embedded in the side wall and has a proximal face and a distal face. The distal face of the radiopaque marker inclines at an angle within a range of from about 45 degrees to about 80 degrees relative to the longitudinal axis of the central lumen. The distal port comprises an elliptical opening with an area that is at least about 105% of a cross-sectional area of the central lumen.
