Non-axisymmetric aortic valve devices
First Claim
Patent Images
1. A device for implantation into a native aortic valve of a mammal comprising:
- a geometrical cross-sectional shape that is not superimposable on itself more than twice during a 360 degree rotation, a base and commissure support members attached to the base;
wherein the members flare outwardly from the base at an angle of from about 1°
to about 30°
from a line perpendicular to the outer edge of the geometrical shape.

Abstract
The present disclosure provides aortic valve prosthetic devices that are constructed in a non-axisymmetric shape, or are expandable to a non-axisymmetric shape for improved results in the repair of defective aortic valves. The devices can be surgically implanted, or they can be implanted percutaneously through an insertion catheter. The expandable devices can be self-expanding or expanded by an inflatable balloon to a non-axisymmetric cross-section geometry.
