ABSTRACT:
A stentless aortic heart valve having a disposable holder with a removable handle can be manually reversed by the physician during suturing to provide a relatively unobstructed view into the patient's aorta. A covering applied to strategic regions on the exterior and interior of the device provides a firm ground for suturing the prosthetic heart valve into position, and for attaching the detachable holder.
