STENT- BALLOON ASSEMBLY

摘要

The present invention relates to an assembly comprising at least one expandable stent (2) for use in affected vessels, at least one balloon (1) in said stent providing the required expansion, and a graft (3) enveloped around said stent, characterized in that said balloon (1) can be inflated from an initial state (1) to an inflated state (1a) with a larger diameter, said stent (2) surrounding said balloon is expanded to a diameter (2a) that is larger than that of the original stent (2), this expanded state is a stable state not restoring to the original state of the stent, the extent of expansion is adjusted by the amount the balloon is inflated, and said graft (3) enveloped around said stent (2) expands in line with the amount the stent (2) is expanded to a state with a larger diameter (3a).
