Abstract
An infra-annular annuloplasty prosthesis is disclosed including a flexibly semi-rigid frame, a portion of which is shaped to conform to the scalloped configuration of the normal circumference of an arterial heart valve annulus. Axially projecting legs spaced circumferentially to correspond to the location of tissue adjacent to the valve commissures are provided for support and anchoring of the annulus-conforming portion to the dense fibrous tissues adjacent each commissure. The prosthesis includes a one-or two-part frame having scalloped upper and lower edges defining peaks and valleys. The upper edge is shaped to follow the contour of the tissue underneath the valve leaflets, and thus supports the leaflets and aortic wall from below. The lower edge is similarly scallop-shaped, but with less pronounced peaks and valleys than the upper edge, and is thus shaped to conform to the aortic annulus shape and provide support directly thereto.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
