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.

Claims

1. A stent supporting device implanted into an aorta, comprising:

an anchoring stent inserted into and fixed to a branch blood vessel adjacent to the aorta into which the stent is implanted; and

a connection member for connecting the anchoring stent and the stent.

2. The stent supporting device according to claim 1, wherein the connection member connects the most adjacent ends of the stent and the anchoring stent.

3. The stent supporting device according to claim 2, wherein the connection member connects a peak of a hoop of the stent and a peak of a hoop of the anchoring stent between the ends of both.

4. The stent supporting device according to claim 1, wherein the connection member is a wire, and the wire ties the stent and the anchoring stent, producing a predetermined space between the stent and the anchoring stent, so that the stent and the anchoring stent are connected to rotate freely around each other.

5. The stent supporting device according to claim 4, wherein the connection member is a plurality of wires.

6. The stent supporting device according to claim 1, wherein the connection member is a ring, and the ring connects the stent and the anchoring stent, producing a predetermined space between the stent and the anchoring stent, so that the stent and the anchoring stent are connected to rotate freely around each other.

7. The stent supporting device according to claim 6, wherein the connection member is a pair of rings connected in the form of the numeral “

8.”

8. The stent supporting device according to claim 6, wherein the connection member comprises a plurality of rings connecting the stent and the anchoring stent.

9. The stent supporting device according to claim 7, wherein the connection member comprises a plurality of ring chains connecting the stent and the anchoring stent, each chain being a pair of rings connected in the form of the numeral “

8.”
