摘要:
A prosthetic implant for treating a diseased aortic valve is described. The prosthetic implant includes a substantially tubular body configured to be positioned in an aorta of a patient, at or near the patients aortic valve. The body includes a lumen extending through the body from a proximal end to a distal end of the body and an adjustable frame surrounding the lumen. The prosthetic implant further includes at least one adjustable element located in or on the body and extending at least partially around a circumference of the lumen. The at least one adjustable element includes a shape memory material and is transformable, in response to application of an activation energy, from a first configuration to a second configuration, wherein the first configuration and second configuration differ in a size of at least one dimension of the at least one adjustable element. The at least one adjustable element may engage at least one of a root of the aorta, an annulus of the aortic valve, and the patients left ventricle, when the at least one adjustable element is in the second configuration.
