One thing special about the Crea Aortic Valve is its unique shape. Crea Aortic valve has a design with both concave and convex parts that fit exactly to the aorta's structure. The stent has a special design with a concave shape that anchors firmly at the annulus. The convex part of Crea Aortic valve fits tightly in the sinus Valsalva, sealing the annulus very well.

• Dual cell configuration

The Crea Aortic Valve has a special design with two cell types that make it work better and safer. The bottom part of the valve is made with closely packed cells, giving it a strong radial force to stay securely in place. Meanwhile, the open cell design at the top makes sure that coronary arteries stay unblocked. 

• Differential radial force

Another important characteristic of the Crea Aortic Valve is its differentiating radial force. This design makes sure that the valve gives more radial force at the bottom part to hold firmly while applying less radial force at the top part to avoid damage to the aorta. 

• Commissure design

The commissure design of the Crea Aortic Valve makes it very special. The way they connect the leaflets is done with great care to make sure there is a smooth connection, strong durability, and accurate placement of the valve. This design not only makes the valve last longer but also ensures it works very well during its life.

• Optimized effective orifice area (EOA)

The Crea Aortic Valve has an improved Effective Orifice Area (EOA), which is very important for good blood flow. When the EOA is bigger, it means there is less resistance to blood moving through, and this can make the heart work less hard. The Crea Aortic Valve manages this issue by having an outer skirt design, made to stop PVL as much as it can. 

• Mechanically simple delivery system

The delivery system of the Crea Aortic Valve is made to work very well. It has a handle that turns smoothly and offers exact 1:1 rotation, so the valve can be placed exactly where it should go. The simple delivery system not only makes the process easier for doctors but also cuts down mistakes when doing implantation.

• Recapturable & repositionable

One very new thing about the Crea Aortic Valve from Onecrea Medical TAVI is that it can be recaptured and repositioned. This means if doctors do not place it right at first, they can adjust or move the valve without taking it out completely. 

It has special design features like concave and convex shapes, a cell layout, different radial forces, and better EOA. These make it much better than older models of valves. Also, the outer skirt design to stop PVL, the easy-to-use delivery system, and the valve's ability to be recaptured and repositioned all help make it work very well and lead to good results for patients.
