CA 2664497

A synthetic blood vessel graft (e.g., for use with a prosthetic heart valve) includes a mounting cuff adjacent at least one end for facilitating attachment of the graft to another structure (e.g., a sewing cuff of a heart valve). The mounting cuff may be sized and shaped to provide good conformance to the target structure to which it may be attached (e.g., the heart valve sewing cuff). The graft is preferably preclotted. Especially for use with a tissue valve (which must be supplied in a packaging solution that would react with a preclotting agent), the graft is preferably supplied separately from the valve.

L'invention concerne un greffon vasculaire synthétique (par ex., à utiliser avec une valvule cardiaque prothétique) comprenant un manchon de montage au voisinage d'au moins une extrémité, pour faciliter la fixation du greffon à une autre structure (par ex., un manchon de suture d'une valvule cardiaque). Le manchon de montage peut présenter une taille et une forme s'adaptant bien à la structure cible à laquelle il peut être fixé (par ex., le manchon de suture de valvule cardiaque). Le greffon est de préférence précoagulé. Utilisé notamment avec une valvule tissulaire (qui doit être fournie dans une solution de conditionnement susceptible de réagir avec un agent de précoagulation), ledit greffon est de préférence fourni séparément de la valvule.
