It is described as:
"The Perceval S is a surgical aortic valve with a unique self-anchoring frame which enables the surgeon to replace the diseased valve without suturing it into place. It is comprised of a functional component made of bovine pericardium fixed in a super-elastic alloy frame. This unique frame design is characterized by two ring segments which are specially designed to match the anatomy of the sinus and thus to allow the anchoring of the prosthesis to the aortic root. Perceval S provides minimal transvalvular gradient due to an optimal ratio between internal and external device diameter. The system features a stentless aortic pericardial valve that has been implanted in more than 10,000 patients with proven durability and optimal hemodynamics.
The Perceval S valve is designed to replace both native aortic valves and other aortic prosthetic devices, and designed to enable the surgeon to use minimally invasive techniques when implanting the valve, which has the potential to significantly cut down on time in the operating room. Minimally invasive surgery has been shown to reduce patient time under anaesthesia and post-operative complications."
