Abstract: Disclosed is a stent supporting device. The support device anchors a stent in a manner such that an anchoring stent is inserted into a branch blood vessel adjacent to an artery in which the stent is disposed, and the anchoring stent is connected to the stent. Accordingly, the support device is safe because it does not use subsidiary members such as screws, which can injure a blood vessel. Further, since the support device allows the stent to have a length corresponding to the size of a treatment site, that is, the stent does not need to be longer than the size of the treatment site, it is easy to install the stent.

Abstract: A catheter includes a main body; a first and a second lumen provided in the main body, wherein a first and a second guide wire are insertable in the first and second lumens, respectively; a first inclined surface provided, on a side of the center axis line, such that the first inclined surface is inclined frontward to approach the center axis line; a first opening formed in the first inclined surface and through which the first lumen opens outward; a second inclined surface provided, on the other side of the center axis line, such that the second inclined surface is inclined frontward to approach the center axis line; and a second opening formed in the second inclined surface and through which the second lumen opens outward.
