PROSTHETIC HEART VALVE AND DELIVERY APPARATUS |
摘要 |
Embodiments of the present disclosure provide a prosthetic heart valve and a heart valve delivery apparatus for delivery of the prosthetic heart valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. In one embodiment, a self-expanding valve comprises an expandable stent that is shaped to maintain the valve in the aortic annulus against axial without anchors or retaining devices that engage the surrounding tissue. A delivery apparatus for delivering s self-expanding prosthetic valve can be configured to allow controlled and precise deployment of the valve from a valve sheath so as to minimize or prevent jumping of the valve from the valve sheath. |
