An externally supported, tape-reinforced tubular prosthetic graft and method of manufacturing therefore. The graft comprises a tubular base graft formed of expanded, sintered fluoropolymer material, a strip of reinforcement tape helically wrapped about the outer surface of the tubular base graft and attached thereto, and, an external support member helically wrapped around the outer surface of the reinforcement tape and attached thereto. The helical pitch of the reinforcement tape is different from the helical pitch of the external support member. Preferably, the helical pitch of the reinforcement tape is in a direction which is opposite the direction of the external support member.
On décrit une greffe tubulaire à bande de renforcement et support extérieur, ainsi qu'un procédé de fabrication de celle-ci. Cette greffe comprend une greffon de base tubulaire formé dans un matériau fluoropolymère fritté, expansé, une longueur de bande de renforcement enroulée de façon hélicoïdale autour de la surface extérieure du greffon tubulaire et fixée sur celui-ci, ainsi qu'un élément de support extérieur enroulé de manière hélicoïdale autour de la surface extérieure de la bande de renforcement et fixé sur celle-ci. L'inclinaison des spires de la bande de renforcement est différent de celle de l'élément de support extérieur. De préférence, les spires de la bande de renforcement sont inclinées dans le sens opposé à celles de l'élément de support extérieur.
