Abstract

ENDOVASCULAR EXPANDER, OF NON MIGRANT POSITIONING; including a tubular body--generally structured by a wire mesh--which, tensed in the sense of its diametrical expansion against the internal surfaces of the vessel of application, is able to be introduced in it in order to maintain or increase the lumen of said vessel; wherein, outwardly, the expander has a plurality of unidirectional anchorages in proximal arrangement to said tubular body and in the sense of its generatrix; each one of said anchorages possesses two opposite ends of--union to the body of the expander and of vascular anchorage, respectively--of which: that one of union is articulable with respect to said body, while that one of vascular anchorage, as of said link is projected freely in proximal arrangement to the body of said expander; so that, being said endovascular expander applied--the anchorage ends being oriented in equal direction to that of the flow of the bloodstream--said anchorages are capable of opening in contraposition to the migrant effect of the expander.
