Abstract
Abstract The present invention provides a prosthetic valve and a sewing cuff assembly for attaching the prosthetic valve in a patient's heart. The suture cuff generally includes at least one lock ring and sewing cuff material disposed at least partially around the lock ring. The valve body includes a peripheral groove for receiving the lock ring therein and securing the lock ring thereto. A stiffening ring may be coupled to the peripheral groove or otherwise provided on the valve body.
