Simultaneous rotating separator, irrigator microcatheter for thrombectomy and method of use

An endovascular device for protecting the three great vessels of the aortic arch and the outflow to the descending aorta simultaneously by capturing and removing emboli comprising:

• an aspiration catheter comprising a proximal end, a wall that comprises a circumference and that spans the proximal end to a distal end, wherein the wall of the aspiration catheter defines a luminal space, a first opening at the proximal end of the aspiration catheter, and a second opening at the distal end of the aspiration catheter;
• a central tube disposed within the luminal space of the aspiration catheter, the central tube comprising a proximal end, a wall that comprises a circumference and that spans from the proximal end to a distal end, wherein the wall of said central tube defines a luminal space, a first opening at the proximal end of said central tube, and a second opening at the distal end of said central tube;
• a retaining structure connected to the distal end of said central tube and extending in a direction from the distal end to the proximal end of said central tube, said retaining structure adapted to resist deformation, wherein a width of said retaining structure is less than a diameter of the luminal space defined by the aspiration catheter;
• wherein said retaining structure has at least one bend;
• at least one flared, semi-permeable filter adapted to allow passage of blood cells and serum and to capture emboli, said at least one semi-permeable filter directly attached to the distal end of the aspiration catheter,
• wherein when said at least one semi-permeable filter is disposed between one or more said retaining structure and said central tube, said at least one semi-permeable filter is confined to a folded shape having a width less than the diameter of the luminal space defined by the aspiration catheter;
• wherein when said at least one semi-permeable filter is not disposed between the one or more retaining structures, said at least one semi-permeable filter comprises a flared shape with a width greater than the diameter of the aspiration catheter, and is adapted to capture emboli and direct emboli toward the second opening of the aspiration catheter for removal through the luminal space of the aspiration catheter.
