Abstract
A neurovascular catheter having an atraumatic navigational tip is disclosed. The catheter includes an elongate flexible tubular body, a distal zone of the tubular body comprising: a tubular inner liner; a helical coil surrounding the inner liner and having a distal end, a tubular jacket surrounding the helical coil, and extending distally beyond the helical coil distal end to terminate in a catheter distal face, and a tubular radiopaque marker embedded in the tubular jacket. The catheter distal face comprises a first section that resides on a first plane which crosses a longitudinal axis of the tubular body at a first angle within the range of from about 35 degrees to about 55 degrees, and a second section that resides on a second plane which crosses the longitudinal axis of the tubular body at a second angle within the range from about 55 degrees to about 90 degrees.
