Title
(EN) SYSTEMS AND METHODS FOR POSITIONING A HEART VALVE USING VISUAL MARKERS
(FR) SYSTÈMES ET PROCÉDÉS DE POSITIONNEMENT D'UNE VALVULE CARDIAQUE À L'AIDE DE MARQUEURS VISUELS
Abstract
(EN)
A valve retainer is connected to an elongate delivery member. The valve retainer is configured to releasably secure a prosthesis (e.g., a heart valve prosthesis) to the delivery member during delivery to a target site in a body (e.g., a native valve annulus). The valve retainer includes a rotational identifier that identifies the rotational orientation of the valve retainer when the valve retainer is positioned proximate to the target site. A heart valve prosthesis can include a commissural post that has a predetermined rotational position relative to the rotational identifier, such that the heart valve prosthesis can be rotationally aligned with the native commissures of the native valve by rotating the delivery member and the valve retainer until the commissural post is aligned with a native valve commissure and the rotational identifier is visible.
(FR)
Selon l'invention, un dispositif de retenue de valvule est relié à un élément de pose allongé. Le dispositif de retenue de valvule est configuré pour fixer de manière libérable une prothèse (par exemple, une prothèse de valvule cardiaque) à l'élément de pose durant la pose au niveau d'un site cible dans un corps (par exemple, un annulus de valvule native). Le dispositif de retenue de valvule comprend un identificateur de rotation qui identifie l'orientation en rotation du dispositif de retenue de valvule lorsque le dispositif de retenue de valvule est positionné à proximité du site cible. Une prothèse de valvule cardiaque peut comprendre un montant commissural qui a une position en rotation prédéterminée par rapport à l'identificateur de rotation, de telle sorte que la prothèse de valvule cardiaque peut être alignée en rotation avec les commissures natives de la valvule native par rotation de l'élément de pose et du dispositif de retenue de valvule jusqu'à ce que le montant commissural soit aligné avec une commissure de valvule native et que l'identificateur de rotation soit visible.
