Abstract

L'invention porte sur un obturateur de calibrage pour valvule sigmoïde prothétique utilisé afin de déterminer les dimensions correctes d'un anneau aortique. Cet appareil comporte un corps obturateur cylindrique pourvu d'une collerette l'encerclant. La surface inférieure de la collerette, au moins, n'est pas plate, décrit plusieurs courbes afin d'être complémentaire, de par sa forme, de l'anneau de la valvule sigmoïde, une fois en place, durant le calibrage. On peut installer dans le corps obturateur cylindrique un connecteur à manche auquel il est possible de rattacher un manche durant la mise en place de l'obturateur dans l'anneau aortique. Cette invention concerne également des méthodes de détermination des dimensions d'un anneau de valvule sigmoïde faisant intervenir plusieurs obturateurs de calibrage de valvule sigmoïde de différentes tailles tels qu'ils ont été décrits ci-dessus et consistant à les positionner l'un après l'autre dans l'anneau aortique jusqu'à ce qu'il s'en soit trouvé un qui convienne.
