| 摘要 |
The present invention provides stents for deploying within tubular organs, blood vessels, or other tubular body lumens. Such stents comprise a stent body comprising an elastic material, the stent body being characterized by a free cylindrical shape having a free diameter. The stent body is at least partially covered with a covering that substantially prevents the stent body from expanding towards its free diameter when the stent body is placed into a diameter smaller than the free diameter. In one embodiment, the covering is a metal coating on the stent body. In another embodiment, the covering is a tube, or multiple tubes, around the stent body. Also provided is a method for deploying the stents of the present invention within tubular organs, blood vessels, or other tubular body lumens. <IMAGE> |
