Catheters, Vascular, Embolectomy/Thrombectomy, Blending
Definition : Embolectomy/thrombectomy catheters that aspirate and liquefy the thrombus and recirculate the particles, in action similar to that of a blender, progressively reducing the size of the particles (typically to less than 13 um). These catheters include an impeller at their distal tip, mounted on a drive shaft in a metal housing that has sideports for recirculation. The impeller is driven by an external motor at high speed (typically 150,000 rpm). Blending embolectomy/thrombectomy catheters work well in cases of recent thrombosis, particularly in polytetrafluoroethylene grafts.
