Embodiment Construction

[0037] figure 1 A schematic, representative cross-sectional view of a human heart 20 is shown having a right atrium 31 and a right ventricle 32 communicating through a tricuspid valve 33 , and a left atrium 41 and a left ventricle 42 communicating through a mitral valve 43 . The tricuspid valve 33 has three leaflets 34, figure 1 Only two are shown in , the leaflets 34 are tethered to the wall 37 of the right ventricle by the chordae 35 and papillary muscles 36 . Right ventricle 32 communicates with pulmonary artery 38 through pulmonary valve 39 . The mitral valve 43 has two leaflets, respectively the anterior leaflet 44 (the anterior leaflet 44 is continuous with the wall of the aorta) and the posterior leaflet 45, the two leaflets are supported by the mitral annulus 46 and extend from the mitral The annulus 46 is extended. The mitral valve leaflets 44 and 45 are each tethered to the ventricular wall 49 by the chordae 47 and papillary muscles 48 . The left ventricle commun...

Abstract

A method of replacing a native heart valve with a prosthetic heart valve, the method comprising: deploying a wire mesh stent in a chamber of the heart on the retrograde side of the native heart valve; while the stent is deployed on the retrograde side of the valve, placing A prosthetic heart valve is placed in place of the native heart valve; the prosthetic heart valve is deployed to replace the native heart valve; and the stent is shrunk to a deflated state and the deflated stent is removed from the chambers of the heart.

Description

[0001] related application [0002] This application claims priority under 35 USC, Section 119(e), US Provisional Application 61 / 888,048, filed October 8, 2013, the contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the invention relate to cardiac prostheses and delivery systems for cardiac prostheses. Background technique [0004] The human heart, and generally the hearts of all mammals, includes two blood pumps that operate in sync with oxygenation and deliver oxygenated blood to the body. After the oxygenated blood flows through the blood vessels in the circulatory system to deliver oxygen and nutrients to various parts of the body, the first pump receives the deoxygenated blood and pumps the deoxygenated blood to the lungs to be oxygenated. The second pump receives oxygenated blood from the lungs and pumps it through the blood vessels of the circulatory system and delivers oxygen and nutrients to parts of the body. Two pumps...
