Title
(EN) VASCULAR GRAFT WITH IMPROVED SURFACE FLOW
(FR) IMPLANT VASCULAIRE A ECOULEMENT DE SURFACE AMELIORE
Abstract
(EN)
An ePTFE vascular graft having a smooth PTFE luminal surface which is substantially non-adhesive to occlusive blood components. Preferably the graft is a longitudinally extruded and expanded ePTFE tube of about 10-30 microns mean fibril length and is provided with a luminal surface covering of an ePTFE film of small mean fibril length (5 microns or less) which provides the smooth luminal PTFE surface. The graft is anticipated to be particularly effective as a small diameter graft (6 mm or smaller). It is anticipated to have utility as a conventional vascular graft, as a cardiovascular patch and as an intraluminal vascular graft (6 mm or smaller) and as a covering for stents.
(FR)
L'invention concerne un implant vasculaire en polytétrafluoréthylène expansé (PTFEe), présentant une surface luminale lisse en PTFE sensiblement non adhésive vis-à-vis des constituants sanguins occlusifs. Cet implant est constitué de préférence d'un tuyau en PTFEe extrudé et expansé d'une longueur de fibrille moyenne d'environ 10-30 microns et pourvu d'un revêtement de la surface luminale constitué par une pellicule en PTFEe de faible longueur de fibrille moyenne (5 microns ou moins) qui lui confère une surface luminale lisse en PTFEe. L'implant de l'invention est, pense-t-on, d'une grande efficacité en tant qu'implant de petit diamètre (6 mm ou moins), et il est également utile en tant qu'implant vasculaire classique, comme plaque cardio-vasculaire, implant vasculaire intraluminal et revêtement pour extenseurs.
