The present invention relates to a fabric for the construction of knitted tubular grafts for use in cardiovascular surgery and to methods of manufacturing these grafts. The fabric of the present invention is constructed so that grafts formed from it will have an increased hoop modulus. This is achieved by knitting the fabric using a stitch which has an underlap of greater than two needle spaces in the bar nearer to the technical face.
La présente invention concerne un tissu destiné à la réalisation de greffons tubulaires à mailles s'utilisant en chirurgie cardio-vasculaire, et à des procédés de fabrication de ces greffons. Le tissu de la présente invention est conçu de sorte que les greffons obtenus à partir de celui-ci puissent avoir un module d'élongation circonférentiel supérieur. On obtient cet effet en tricotant le tissu au moyen d'une maille qui possède une jetée sous, supérieure aux deux espaces d'aiguille se trouvant dans la barre la plus rapprochée de la face technique.
