An arteriovenous graft system is disclosed including an arteriovenous graft (12) that is well suited for use during hemodialysis. In order to minimize or prevent arterial steal, at least one valve device (24) is positioned at the arterial end of the arteriovenous graft. In one embodiment, the system includes a first valve device (24) and a second valve device (26) positioned at the arterial and venous ends respectively. In one embodiment, the valve devices may include an inflatable balloon (28/30) that, when inflated, constricts and closes off the arteriovenous graft.
L'invention concerne un système de greffe artérioveineuse comprenant une greffe artérioveineuse (12) qui est bien adaptée à une utilisation pendant une hémodialyse. Afin de réduire au minimum ou d'empêcher le vol artérien, au moins un dispositif de valve (24) est positionné au niveau de l'extrémité artérielle de la greffe artérioveineuse. Dans un mode de réalisation, le système comprend un premier dispositif de valve (24) et un second dispositif de valve (26) positionnés respectivement aux extrémités artérielle et veineuse. Dans un mode de réalisation, les dispositifs de valve peuvent comprendre un ballonnet gonflable (28/30) qui, lorsqu'il est gonflé, serre et ferme la greffe artérioveineuse.
