Endovascular support device (1), used in particular in angioplasty, structurally strong and feasible to different forms of vessels bifurcations affected by stenosis, without interfering with the vessel flow and without leaving the vessels walls uncovered and comprising a proximal side-branch (3), a first distal side-branch (4) and a second distal side-branch (5), placed in a substantially Y-shaped configuration each one of them comprising a line of tubular segments radially expandable having a wire-like element (6) conformed in extensible turns (7) and laying on a substantially cylindrical surface and a linking segment (11) between said side-branches (3, 4, 5) having at least one wire-like element (6') conformed in successive extensible turns (7) and laying on a two-lobe (12, 13) surface, said proximal side-branch (3) and said first and second distal side-branch (4, 5) being fixed to the linking segment (11). |
