The 'big four' mechanical valves available in the USA are made by ATS Medical, Carbomedics, On-X, and St. Jude. You can find their websites with GOOGLE.
I am impressed with the technological advancements available from On-X (see www.onxvalves.com and www.heartvalvechoice.com). The Ox-X valves have been approved by the FDA for a study using LOW and NO Anti-coagulation in Low and Mild Risk patients. This study will continue until 2015. The benefits (lower risk of clot formation and lower risk of damage to blood cells) come with the valve, regardless of the results of the anti-coagulation studies.
The Gold Standard for Longevity belongs to St. Jude whose valves have been around for 30 years. (see www.SJM.com).
ATS and Carbomedics are 'spinnoffs' of the St. Jude Valves.
ALL 4 use Pyrolytic Carbon for the leaflets which was designed for use in the Nuclear Power industry by the same person (my mind has gone blank!....) who subsequently has made a career out of designing Heart Valves. He is the founder of On-X which produces his 'latest and greatest' design.
