摘要

The stent has a hollow cylindrical body (2) which is formed by braiding around the periphery of it. The braiding has a large opening enabling the inside of the hollow cylindrical body to be accessed by a peripheral surface. A channel (4) which is to be repeatedly opened and closed is formed by closing device that close the opening when the channel is closed and surround a treatment device (6) when the channel is open, when the treatment device is introduced into the opening.
