heart valve

Abstract

The present application provides expandable cardiovascular prosthetic implants. The implant has two inner rings that support a one-way valve that allows flow through the implant. The implant has an outer ring positioned between and extending radially past two inner rings. The implant has anchors attached to the heart tissue to aid in placement of the implant in the annulus of the native valve.

Description

[0001] Incorporation by reference of any priority application [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 294,945, filed February 12, 2016, and U.S. Provisional Patent Application Serial No. 62 / 413,924, filed October 27, 2016, the entire contents of these priority applications It is expressly incorporated herein by reference. technical field [0003] The present disclosure relates to medical methods and devices and, in certain arrangements, to methods and devices for percutaneously implanting valves. Background technique [0004] The human heart has four chambers: the right and left atria, and the right and left ventricles. The atria receive blood and pump it into the ventricles. The ventricles are stronger than the atria and generate the pressure needed to pump blood through the body. The right ventricle pumps blood through the pulmonary circulation to oxygenate the blood. The left ventricle pumps oxygenated blood throu...
