Title
(EN) SELF GROWING HEART VALVES
(FR) VALVULES CARDIAQUES À CROISSANCE AUTONOME
Abstract
(EN)
Described herein are artificial valves that have a frame and leaflets that grow or expand with a patient. Upon placing the valve inside the patient, the valve expands as the annulus of the patient expands. The frame of the valve is configured to expand which in turn causes the leaflets to expand (e.g., to grow). The valve includes a thin undulating wire embedded inside the leaflets. As the annulus of the patient grows, the frame expands, and as the frame expands, the leaflets grow. The growth or expansion of the leaflets is configured so that the valve continues to operate properly (e.g., the leaflets continue to coapt) with expansion of the annulus. The change in size of the valve can be configured to accommodate changes in size of the annulus from an infant or child to an adult.

L'invention concerne des valvules artificielles comprenant une armature et des feuillets qui grandissent ou se dilatent avec un patient. Lors de la mise en place de la valvule dans le patient, celle-ci se dilate lorsque l'anneau du patient se dilate. L'armature de la valvule est configurée pour se dilater, ce qui amène à leur tour les feuillets à se dilater (par exemple, à grandir). La valvule comprend un fil ondulé mince intégré dans les feuillets. Lorsque l'anneau du patient grandit, l'armature se dilate, et lorsque l'armature se dilate, les feuillets grandissent. La croissance ou la dilatation des feuillets est conçue de telle sorte que la valvule continue à fonctionner correctement (par exemple, les feuillets continuent à coopérer) avec la dilatation de l'anneau. Le changement de taille de la valvule peut être configuré pour s'adapter aux changements de taille de l'anneau qui surviennent chez le nourrisson ou l'enfant jusqu'à l'âge l'adulte.
