Problems solved by technology

However, the degenerative changes normally found in the aortic valve are not present in the regurgitation experienced by the mitral valve, and the mitral valve annulus is therefore usually thinner than that of a diseased aortic valve
The thinner mitral annulus makes it relatively difficult to properly position the replacement mitral valve in the native mitral annulus
The general anatomy of the mitral annulus also makes it difficult to properly hold a replacement mitral valve in place

Embodiment Construction

[0099] The present invention generally relates to heart valve support structures suitable for implantation in or near a native heart valve or native valve annulus, and for providing support for replacement heart valves. The support structure is adapted to interact with the replacement heart valve to secure it at an implantation location in or near the native valve or native valve annulus. In some embodiments, the support structure is adapted to be positioned in or near the mitral annulus and is adapted to interact with a subsequently placed replacement mitral valve to hold the replacement mitral valve in place in place of the native mitral valve function of the flap.

[0100] The present invention also provides a two-step endovascular implantation procedure for replacing a patient's native mitral valve. Typically, the support structure is first positioned in or near the mitral valve annulus and held in place. The replacement mitral valve is then secured to the support struct...

Abstract

The present invention is primarily directed a prosthetic cardiac valve support device adapted for endovascular delivery to a cardiac valve, comprising a single ring-shaped support element having an inner diameter and an outer diameter, wherein said support element has an outer perimeter that is entirely rigid, wherein said support element is fitted with one or more intraventricular and/or intra-atrial stabilizing elements, and wherein said support element has a collapsed delivery configuration and a deployed configuration.

Description

Background technique [0001] Heart valve regurgitation occurs when the heart valve leaflets do not close completely during systole. As the heart contracts, blood backs up through the valve leaflets that don't close properly. For example, mitral regurgitation occurs when blood regurgitates through the mitral valve and into the left atrium during ventricular contraction. [0002] In some cases, regurgitation occurs due to leaflet disease (eg, primary or "organic" regurgitation). Regurgitation can also be caused by dilation of the left ventricle, which causes secondary dilation of the mitral annulus. The dilation of the annulus causes the leaflets of the mitral valve to spread apart and create poor tip cooptation and secondary leakage, or so called "functional regurgitation". [0003] Currently, primary regurgitation is corrected by modifying the native valve leaflets, eg, by clips, sutures, hooks, etc., to allow them to close completely during systole. When the disease is too...
