Abstract

The implantable heart valve can have an inverted configuration and can include a support structure and at least two valve leaflets. Preferably, when the valve is placed in proximity with an aortic valve implantation site of a subject and engaged with the implantation site, the valve leaflets are configured to deflect towards the aortic wall into a first position for resisting the flow of blood towards the left ventricle and configured to deflect away from a aortic wall into a second position for allowing the flow of blood from a left ventricle, with the support structure configured to remain static during leaflet deflection.

Description

technical field [0001] The present invention generally relates to medical devices and methods. More particularly, the present invention relates to prosthetic heart valves, structures for providing scaffolding of body cavities, and devices and methods for delivery and deployment of these valves and structures. Background technique [0002] Diseases and other abnormalities of the heart valves affect the normal flow of blood from the heart. The two types of heart valve disease are narrowing and insufficiency. Narrowing is when the valve cannot open fully because of hardening of the valve tissue. Insufficiency refers to inefficient blood circulation caused by valves that allow blood to flow backwards within the heart. [0003] While some heart valve abnormalities can be treated with drugs, many conditions require replacement of the natural valve with an artificial heart valve. Although repair or replacement of the aortic or mitral valves is most common because they are locat...
