Stent for expanding physiological vessels consisting of a thin-walled metal cylindrical tubular element (1), said wall comprising a series of perforations determining annular elements (2) and alternately deformable and non-deformable longitudinal elements (3, 4) forming a malleable sleeve (1) which can be radially extended under internal pressure and hold the shape so obtained. The tubular element preferably comprises integrated outward-facing engaging means (7, 8) that prevent any migration of the device. The device of the invention is designed, in particular, to be deployed in an artery or a vein to prevent it from being compressed, in places and facilitate blood flow. |
