COLLAPSIBLE AND RE-EXPANDABLE PROSTHETIC HEART VALVE CUFF DESIGNS AND COMPLEMENTARY TECHNOLOGICAL APPLICATIONS
摘要:
A prosthetic heart valve is provided with a cuff (85, 285, 400) having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion (90) adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements (210, 211, 230, 252, 253) for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness (280) distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part (402) of the cuff may be movable relative to the stent during implantation.
