STENT HAVING VALVE FOR PREVENTING FLOWING BACKWARD

摘要

PURPOSE: A stent with a backflow prevention valve is provided to discharge body fluids and pancreatin stagnating in a pancreas to other organs adjacent to the pancreas by supplying a connection path through a penetration hole which is formed in two organs such as the pancreas and/or a small intestine. CONSTITUTION: A stent (100) with a backflow prevention valve comprises a body part (110) which is arranged with both ends passing through penetration holes which are formed in different organs; the backflow prevention valve (12) which guides flow of liquids from one side of the different organs to the other side being arranged in the connection path; and a flare part (13) which prevents breakaway of both ends in the body part from the penetration hole as the flare part is widened from both ends of the body part to outside. The body part and the flare part are provided with a solid bottom entangling wires in a net structure and contain a cover film (140) which covers the entangled wired to seal the connection path.
