PROSTHETIC HEART VALVES, SUPPORT STRUCTURES AND SYSTEMS AND METHODS FOR IMPLANTING THE SAME,
First Claim
Patent Images
1. A method for implanting a prosthetic valve, comprising:
- placing an implantable valve in proximity with an aortic valve implantation site of a subject;
engaging the valve with the implantation site, wherein the valve comprises a support structure and at least two valve leaflets coupled with the support structure, the valve leaflets 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, wherein the support structure is configured to remain static during deflection of the valve leaflets.

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.

16. A prosthetic valve apparatus, comprising:
-
a support structure configured for implantation within a blood vessel; and at least two valve leaflets coupled with the support structure, the valve leaflets configured to deflect towards the aortic wall into a first position for resisting the flow of blood towards a heart chamber and configured to deflect away from a wall of the vessel into a second position for allowing the flow of blood from the heart chamber, wherein the support structure is configured to remain static during deflection of the valve leaflets. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
