Document Type and Number:
Japanese Patent JP2003524457
Kind Code:
A
Abstract:
Pre-trimmed, cryopreserved homografts and other stentless bioprosthetic heart valves having natural tissue sewing rings formed thereon. The sewing ring may be formed of strip of pericardium or other suitable tissue. Material may be captured between the natural tissue sewing ring and a sub-valvular lip formed on the valve to impart a desired size or shape to the sewing ring. In the case of cryopreserved embodiments of the invention (e.g., cryopreserved human homografts) the sewing ring is attached to the valve by way of a natural tissue suture, biological glue or other attachment component that is capable of undergoing cryopreservation without breaking, excessive weakening, or other changes that prevent it from performing its attachment function.
