Title
(EN) VASCULAR DEVICE
(FR) DISPOSITIF VASCULAIRE
Abstract
(EN)
A vascular device comprises at least one surface for imparting rotational flow velocity components to a fluid passing along a vessel incorporating said device. A particular vascular graft comprises a tubular vessel having a lumen. In cross-section, the lumen has a periphery which is non-circular and the orientation of the non-circular periphery rotates as a function of position along the length of the graft to provide the surface for imparting rotational flow velocity components to a fluid passing along the graft to thereby alleviate the problem of stenosis, particularly at an end-to-side anastomosis.
(FR)
La présente invention concerne un dispositif vasculaire comprenant au moins une surface destinée à conférer des composantes de vitesse d'écoulement rotationnel à un fluide circulant dans un vaisseau dans lequel est placé le dispositif précité. Une greffe vasculaire particulière comprend un vaisseau tubulaire muni d'une lumière. La lumière possède une périphérie de coupe transversale non circulaire dont l'orientation tourne en fonction de sa position sur la longueur de la greffe de façon à produire la surface destinée à conférer des composantes de vitesse d'écoulement rotationnel à un fluide circulant dans la greffe afin d'atténuer le problème de la sténose, en particulier en un point d'anastomose termino-latérale.
