Delivery system

Abstract

A delivery system, including an outer sheath assembly, an inner sheath assembly, and a sealing assembly, where the outer sheath assembly includes an outer sheath core tube; the inner sheath assembly includes an inner sheath core arranged in the outer sheath core tube in a penetrating manner; the sealing assembly includes a first sealing piece; and the first sealing piece is arranged between the inner sheath core and the outer sheath core tube to seal a gap between a proximal end of the outer sheath core tube and the inner sheath core. The delivery system can effectively block blood flowing into a gap between the outer sheath core tube and the inner sheath core, so that the blood is avoided from flowing out of a product, thereby solving the problem of blood leakage of the product.
