A device designed to facilitate the operation of implanting an endovascular stent (201) in a vessel or passage (203, 203c) of the human or animal body employs at least one guide wire (G1, G2) consisting of a linear core (2) associated coaxially with a tubular sheath (3); the sheath (3) is secured to the core (2) at one end (4) and affords at least one weakened lateral area (5) designed to flex and enlarge elastically when subjected to the action produced by a relative axial movement between the core (2) and the sheath (3), in such a way as to expand beyond the normal width of the sheath (3) and engage the wall of the passage (203, 203c), remaining anchored until released by reversing the relative axial movement. |
