摘要： The present invention relates to a stent for intraluminal expansion. The stent for intraluminal expansion comprises an inner stent A, an outer stent B and fixing threads C for fixing these stents as one unit. The outer stent B is inserted over the inner stent A in such a way that the space portions of the inner stent A and the space portions of the outer stent B are alternated with each other, so the outer surface of the inner stent and the inner surface of the outer stent are in close contact with each other, and both ends of the outer stent and inner stent are fixed as one unit by fixing threads C. According to the stent for intraluminal expansion of the present invention, in which form recoverability of each of the inner stent A and the outer stent B is excellent, expansion is easy after it is inserted into the lumen body because the cylindrical film membrane is not fixed by fixing thread C, and the space portions Id of the inner and outer stents are overlapped alternately with each other so that it is possible to effectively prevent cancer cells, etc. from penetrating into the lumen.

摘要： An artificial blood stent insertion device is disclosed. The front end portion, middle portion and rear end portion of the artificial blood stent 1 inserted into an outer tube 2 are tied, respectively, in such a manner to be surrounded by a fixing wire 6 having ring-shaped loops 6a at both sides, the fixing wire 6 is fixed by a core 5 passing through the loops 6a, and the core 5 passes through the moving tube so that one end thereof is projected to one side of a grip 8. A patient does not need to take antihypertensive agents before an operation because the artificial blood stent 1 can be easily inserted and fixed to a desired position in a blood vessel without being affected by blood pressure. No knitting is required when tying the artificial blood stent by the fixing wire 6, thereby simplifying the preparation for an operation. The artificial blood stent 1 is kept contracted over the entire length until the removal of the core 5, which makes it easier to adjust the placement position of the artificial blood stent 1 in the blood vessel.

摘要： The present invention relates to an inserting device of artificial blood stent. The inserting device of artificial blood stent is characterized in that the cylindrical artificial blood stent 1 comprises a body Ia of a hollow cylindrical woven stuff and a cylindrical stent member Ib connected to the bottom end portion of said body Ia, and inverting devices 5 are connected on both sides of one end portion of the body Ia of said cylindrical artificial blood stent, and both distal ends 5a of said inverting device 5 are protruded to one side of the handle 8. According to the present invention, because the stent member Ib of the artificial blood stent is expanded inside the front end portion of the stent body Ia that is inverted while it is coming lastly out of the outer tube 2, it is possible to easily insert and fix the artificial blood stent 1 at the desired location in the blood vessel without being affected by blood pressure, so it has an advantage that the patient does not need to take hypotensive drug before operation. Another advantage is that the operation preparatory work is simplified because the work of tying the artificial blood stent 1 with a separate fixing wire is not necessary.
