Abstract
A clot evacuation catheter includes a hollow tubular body disposed within an outer lumen. The tubular body is elongate and includes a selectively rotatable cutting blade disposed within a distal portion thereof to cut clots occluded in at least one opening of the cutting blade. The tubular body also includes a fluid conveying irrigation lumen to deliver fluid to a distal end of the catheter at predetermined times. In an alternative embodiment of the present invention, a hood member extends from the distal portion of the tubular body. The hood member has a distal end that is spaced from, but coaxial with, the distal portion of the tubular body through a side portion of the hood member.
