摘要

A device comprising a catheter (1) with a set of balloons (3)(4) of different diametral expansion capacity provided with respective independent command paths (3a)(4a); in which the second balloon (4) expands the main body of the stent (10), while the first balloon (3) expands the bendable end portion (11) of the stent (10). The second balloon (4), has a lower diametral expansion capacity and is inflated through the second command path (4a), while the first balloon (3), has a greater diametral expansion capacity and is inflated through the first command path (3a).
