Abstract
A prosthetic heart valve device (100) for percutaneous replacement of a native heart valve includes an expandable retainer (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to the valve support. The retainer forms a donut-shaped flange (190) having an arcuate outer surface (142) for engaging tissue and an inner lumen defining a passage for blood to flow through the valve support. The retainer can include a plurality of circumferentially positioned, resiliency deformable and flexible ribs (114) which are coupled at their downstream ends 116 to the valve support 120. The flexible ribs, in one embodiment, can have a general C-shape configuration with the tips (117) of the flexible ribs and an opening (119) of the C-shape configuration oriented toward a longitudinal axis (101) of the device.
