Title
(EN) VASCULAR GRAFTS WITH MULTIPLE CHANNELS AND METHODS FOR MAKING
(FR) GREFFONS VASCULAIRES À MULTIPLES CANAUX, ET PROCÉDÉS DE FABRICATION
Abstract
(EN) A wall, for example the wall of a vascular graft, has multiple channels within it. The channels may be used to hold drugs or reinforcing fibers. The channels may have a predetermined roughness. The channels may be formed by coextrusion using a soluble material, for example, to define the channels and then dissolving them to open the channels in the extrudate.
(FR) L'invention concerne une paroi, par exemple la paroi d'un greffon vasculaire, contenant de multiples canaux qui peuvent être utilisés pour maintenir des médicaments ou des fibres de renfort. Les canaux peuvent présenter une rugosité prédéterminée et être formés par coextrusion en utilisant un matériau soluble pour définir les canaux, par exemple, puis en dissolvant ledit matériau pour ouvrir les canaux dans l'extrudat.
