摘要： A stent delivery system provided by the present application comprises: a radiopaque tip located at the distal end of the stent delivery system; a beads component comprising at least one expandable part; a funnel component comprising a distal flare structure and a proximal collapsed end, wherein the cross-section of the flare structure gradually increases from its minimum diameter to its maximum diameter along the proximal-to-distal direction; and a core wire located at the proximal end of the stent delivery system; and wherein the distal end of the beads component is fixed on the radiopaque tip and the proximal end of the beads component is fixed on the core wire; wherein the funnel component is coupled with the beads component and the core wire, and is fixed on the core wire through the collapsed end. The present application also provides a flow diversion device and an assembly method of the flow diversion device.
