摘要: A vascular device is provided having a catheter body and rotatable cutter assembly located at the distal end of body. The has least one helical cutting surface within housing that coupled by torque shaft to drive mechanism. conveyor mechanism helically wound about conveys occlusive material conveyed into blade further proximally along for discharge without supplement vacuum pump. manipulated insert lumen advance toward material. operated rotate cut convey from deflected rotated sweep in an arc center axis region larger than outside diameter assembly.
