PROSTHETIC VALVLE FOR INTRALUMINAL IMPLANTATION
First Claim
1. A prosthetic valve assembly for intraluminal implantation into a lumen of a patient for replacing a native deficient valve, the valve assembly comprising:
- an outer balloon expandable support made of a collapsible material and configured to be expanded for anchoring against a lumen wall of the patient and forming a waist section,a core valve support comprising a collapsible and self-expanding support ring configured to be anchored in the outer balloon expandable support once expanded, the support ring including a plurality of flexible posts upwardly extending from the ring, the core valve support being configured to be collapsed for intraluminal implantation and being configured to expand into the lumen and the outer balloon expandable support once the outer balloon expandable support is anchored against the lumen wall, anda plurality of flexible leaflets pivotally connected to the collapsible and self-expanding support ring and posts and configured to move between an open position for permitting a blood flow through the valve assembly and a close position for preventing a backflow through the valve assembly.
