Abstract: A stent is disclosed herein. The stent includes a silicon cover, a plurality of cylindrical members, and connection members. The silicon cover is formed in an open hollow cylindrical shape in which the diameter of both ends thereof is larger than the diameter of the intermediate portion thereof. The plurality of cylindrical members is disposed on the outer circumference of the silicon cover in a hollow cylindrical shape whose both ends are open, and is configured such that the diameter thereof is reduced by external force to be installed in a tubule. The connection members connect facing ones of the plurality of cylindrical members at regular intervals in a single ring shape between the cylindrical members, and have elasticity in a lengthwise direction.

Abstract: A stent that maintains flexibility in a length direction and prevents fatigue failure by securing predetermined durability is disclosed. The stent may includes a plurality of cylindrical members having a hollow cylindrical shape with both ends open, and adapted to decrease a diameter thereof by an external force so as to be mounted in a tubule, and a connecting member connecting cylindrical members confronting each other.
