CA 2297777

The invention concerns an intravascular dilator comprising a central body (3) acting as deflector of the blood flow and thereby increasing the value of shear stress to the artery wall. Flexible spires (4) soldered to the deflector (3) are radially extensible from a first diameter substantially equal to the deflector diameter (3) to a second diameter greater than the artery diameter. Said spires (4) rest against the artery internal wall (2) in operative position.

Dilatateur intravasculaire comportant un corps central (3) agissant comme un déflecteur du flux sanguin et permettant de ce fait d'augmenter la valeur de la contrainte de cisaillement à la paroi de l'artère. Des spires (4) souples soudées au déflecteur (3) sont extensibles radialement depuis un premier diamètre sensiblement égal au diamètre du déflecteur (3) à un second diamètre plus grand supérieur au diamètre de l'artère. Ces spires (4) prennent appui contre la paroi interne (2) de l'artère en position de service.
