Abstract
L'invention concerne une armature pour une bio-prothèse aortique hétérologue constituée d'un corps cylindrique et creux en une matière plastique semi-flexible enduite d'une étoffe médicale définissant deux extrémités ou entrées opposées et totalement ouvertes et au bord desquelles sont cousus les anneaux aortique et de crête d'une valve d'animal, avec un élargissement externe définissant un cordon continu pour une suture correspondante avec un anneau aortique d'un être humain. Selon l'invention, l'extrémité proximale 1 de l'armature a une configuration ondulée avec un nombre de pointes correspondant au nombre de commissures de la valve supportée; l'extrémité distale 2 a des protubérances espacées. L'invention s'applique notamment au domaine médical.
