A stent made of a hollow expandable ring or sleeve is inserted into a body vessel to locally support or strengthen the vessel. The stent includes a compartment filled with a curable material. The stent is fixed to an inflatable balloon and positioned within the vessel at the desired location. When the balloon is inflated, the stent is expanded into a desired shape. A light conducting fiber is introduced into the vessel to irradiate the material to cure the material in the stent, such that the stent retains the desired shape even after the balloon is removed from the body vessel. |
