1. A thrombi removal catheter for use in a thrombi removal system, comprising:
an elongate sheath having a proximal end, a distal end, a side wall that defines a lumen that extends from the proximal end to the distal end, a distal axial opening at the distal end in fluid communication with the lumen, and at least one lateral opening that extends through the side wall to the lumen, the at least one lateral opening being proximally spaced from the distal end;
an elongate member disposed in the lumen of the elongate sheath, the elongate member configured for longitudinal movement relative to the elongate sheath, the elongate member having a proximal position and a distal position relative to a position of the elongate sheath, the elongate member having a proximal blocker element and a distal blocker element that is longitudinally spaced from the proximal blocker element, the proximal blocker element having a longitudinal passage;
the thrombi removal catheter configured such that:
when the elongate member is in the proximal position, the distal axial opening of the elongate sheath is closed by the distal blocker element of the elongate member and the at least one lateral opening of the elongate sheath is open; and
when the elongate member is in the distal position, the at least one lateral opening of the elongate sheath is closed by the proximal blocker element and the distal axial opening of the elongate sheath is open.
