Supra-annular aortic valve
First Claim
1. An aortic prosthetic valve for supra-annular implantation comprising:
- a valve body of generally annular configuration and a valve element movably mounted on the valve body for opening and closing the valve, said valve body terminating in a generally annular base surface;
a scalloped suture ring circumscribing said valve body adjacent said base surface and configured to approximately fit the contour of the Sinuses of Valsalva at the base of the aorta; and
said base surface of said valve body being of a wavy configuration and configured such that it does not project into the annulus at the base of the aorta when the suture ring is in place in the Sinuses of Valsalva whereby the aortic prosthetic valve can be mounted in a supra-annular position and the valve body does not interfere with flow through the annulus.

Abstract
An aortic prosthetic valve for supra-annular implantation comprising a valve body of generally annular configuration and a valve element movably mounted on the valve body for opening and closing the valve. The valve body terminates in a generally annular base surface, and a scalloped suture ring circumscribes the valve body adjacent the base surface. The suture ring is configured to approximately fit the contour of the Sinuses of Valsalva at the base of the aorta. The base surface of the valve body is of a wavy configuration and is configured such that it does not project into the annulus at the base of the aorta, and accordingly, the valve body does not interfere with flow through the annulus. The suture ring has three lobes which fit the Sinuses of Valsalva at the base of the aorta. The valve is configured to minimize disruption of the vortices which develop in the Sinuses of Valsalva to assist in closing the valve.

10. A method comprising:
-
providing an aortic prosthetic valve which includes a valve body of generally annular configuration, a valve element movably mounted on the valve body for opening and closing the valve, and a scalloped suture ring circumscribing the valve body and configured to approximately fit the contour of the Sinuses of Valsalva at the base of the aorta, said valve body terminating in a generally annular base surface of a wavy configuration; and implanting said aortic prosthetic valve in a human heart with the suture ring being received in the Sinuses of Valsalva at the base of the aorta and with the base surface of the valve body being out of the annulus at the base of the aorta so that the valve body does not interfere with flow through the annulus.
