Title: STENT DELIVERY SYSTEM, CORRESPONDING FLOW DIVERSION DEVICE, AND ASSEMBLY METHOD OF FLOW DIVERSION DEVICE
Abstract:
A stent delivery system (10) comprises: a radiopaque tip (11) located at the distal end of the stent delivery system (10); a beads component (12) comprising at least one expandable part (21); a funnel component (13) comprising a distal flare structure (41) and a proximal collapsed end (42), wherein the cross-section of the flare structure (41) gradually increases from its minimum diameter to its maximum diameter along the proximal-to-distal direction; and a core wire (14) located at the proximal end of the stent delivery system (10); wherein the distal end of the beads component (12) is fixed on the radiopaque tip (11) and the proximal end of the beads component (12) is fixed on the core wire (14); and wherein the funnel component (13) is coupled with the beads component (12) and the core wire (14), and is fixed on the core wire (14) through the collapsed end (42). A flow diversion device (50) and an assembly method (600) of the flow diversion device (50) are also provided.
