Abstract:
A delivery system (100), comprising an outer sheath assembly (1), an inner sheath assembly (3), and a sealing assembly (5). The outer sheath assembly (1) comprises an outer sheath core tube (11). The inner sheath assembly (3) comprises an inner sheath core (31) passing through the outer sheath core tube (11). The sealing assembly (5) comprises a first sealing component (51). The first sealing component (51) is disposed between the inner sheath core (31) and the outer sheath core tube (11) to seal a gap between the proximal end of the outer sheath core tube (11) and the inner sheath core (31). The delivery system can effectively block blood flowing between the outer sheath core tube (11) and the inner sheath core (31), so that blood is prevented from flowing out of a product, thereby solving the technical problem of blood leakage of the product.
