o SAPIEN Valve:
§ Cobalt Chromium frame with bovine pericardial leaflets
§ 58-70wt% cobalt 26-30wt% chromium + small amounts of other alloying metals. The most common alloy for medical implants utilizes the addition of 6% molybdenum.
§ The cobalt within Co-Cr alloys forms an alpha phase while the chromium allows the alloy to form a passive oxide layer (Cr2O3) similar to stainless steel. The passivation of the surface allows for high corrosion resistance which is a desirable quality in long term implants.
§ Co-Cr alloys have attractive mechanical properties such as high strength and excellent fatigue resistance.
§ Problems with Co-Cr alloys are that they are expensive and difficult to manufacture to medical standards. Even with the addition of other alloying agent.

What Alloy was once used to make sword blades?
The alloy for sword blades was Damascus steel.
What element was used as an alloy in ball point pens?
Chromium was used as an alloy in ball point pens to improve the strength and durability of the pen tip.
Which two metals are used to form alloy?
Two metals commonly used to form alloys are iron and nickel. When combined, these two metals create a popular alloy known as stainless steel, which is highly resistant to corrosion and heat.
What is Y alloy?
Y alloy is a high-strength, nickel-based alloy that contains aluminum and titanium. It is often used in aerospace applications due to its excellent strength-to-weight ratio and high temperature resistance.
Which farm animals heart valves can be used to replace human valves?

What is the purpose of the valves which connect the heart chambers?
Valves are present in heart are used to prevent backflow of blood in heart due to reduce in pressure in atrium.
Why is heart catheterization used to diagnose pericarditis?
To view the heart's chambers and valves.
What type of medical prodedure uses a plastic valve?
Plastic valves are often used in surgical procedures involving the heart. Heart valve surgery is used to replace or repair diseased heart valves. Artificial valves last around 8-20 years.
What are the medical uses for teflon?

What is an endocardiogram?
This is a procedure that checks the status of the heart chambers and valves. Sound waves are used to produce images of the heart and check for any problem in heart muscles or valves. This exam is usually suggested if a doctor believes that the patients blood is being pumped abnormally.
What is the function of valves in pneumatic systems?
generally when hot gasses or air is used to eitherpropel something or is simply being let out valves are simply devices that can create a one way system - like in the human heart the are valves to stop the blood going back into the heart
How is a pigs heart similar to human heart?
They are similar in size, anatomy, and function. They both have four chambers and four valves, which is why it is sometimes used for a heart transplant

What procedure is used to look at the action of heart valves?
The best procedure to visualize the heart valves and how they are functioning is a Cardiac Catheterization. Very simply, and under no anesthesia, an IV catheter is threaded into the heart so the heart and all it's structures and functions can be visualized and assessed. The patient is awake the whole time, and can see their own heart on the monitor!
