A stent (1) for dilation of blood vessels, such as arteries (10) and the like, comprises a tubular net (2) at the ends of which are two annular elements (5, 6), said stent being suitable to pass from a collapsed configuration in which it assumes a minimum cross sectional diameter in order to be able to be conveyed inside the artery (10) to an expanded configuration in which it assumes a maximum cross-sectional diameter in order to dilate the walls of the part of artery in which it is inserted and keep them in this dilated position; in the expanded configuration the annular elements (5,6) compressing the inner walls (11) of the artery (10) so as not to create any breaks or interruptions in the flow of blood inside the artery (10) and through the stent. <IMAGE> |
