CLOT EVACUATION CATHETER

摘要

A clot evacuation catheter (10) includes a hollow tubular body (12) disposed within an outer lumen (22). The tubular body is elongate, and includes a selectively rotatable cutting blade (14) disposed within a distal portion (2 0) thereof to cut clots occluded in at least one opening (44) of the cutting blade. The tubular body also includes a fluid conveying irrigation lumen (34 ) to deliver fluid to a distal end (35) of the catheter at predetermined times . In an alternative embodiment of the present invention, a hood member (16) extends from the distal portion of the tubular body. The hood member has a distal end (28) that is spaced from, but coaxial with, the distal portion of the tubular body through a side portion (19) of the hood member.
