Hancock II Tissue Valve

Overview

The Hancock® II valve is used to replace defective aortic and mitral valves. Surgeons around the world have been implanting Hancock valves for more than 25 years.

The Hancock II valve is a tissue heart valve obtained from the heart of a pig. A pig's heart anatomy is similar to that of a human heart. The leaflets that control the flow of blood in the Hancock II valve are attached to a flexible frame (stent) for support. The stent is covered with a fine fabric, used to sew the valve into the heart.

The Hancock valved conduit is a polyester fabric cylinder with a Hancock II valve sewn into it. This conduit is used to repair congenital or acquired defects of the aorta.

Placement

The Hancock II valve is used to replace a damaged aortic valve or a damaged mitral valve, depending on your disease condition.

Features

The Hancock II valve is designed to allow the maximum amount of blood to flow through it.1 Studies have shown that the Hancock II valve performs exceptionally well in all age groups and in both aortic and mitral valve replacement.2-4
