Problems solved by technology

The usual anatomy of the mitral valve annulus also makes it more difficult to anchor the replacement mitral valve in place
However, this approach is problematic, especially since it has proven difficult to develop a device that can be folded to have a small enough delivery profile and still be able to expand and secure within the mitral valve via a vascular access site. bit

Embodiment Construction

[0083] As stated above, the present invention generally relates to devices and elements for improving the stability of intracardiac devices. In a set of preferred embodiments, the device is a heart valve support device for use in a two-step valve replacement procedure, preferably at the mitral valve location. In other preferred embodiments, the intracardiac device may be a valve support device intended to be implanted elsewhere within the heart. Furthermore, the stabilizing and anchoring elements of the present invention may also be used to improve the stability of other types of intracardiac devices, such as annuloplasty rings and one-piece prosthetic valves. Thus, while the detailed description that follows relates primarily (but not exclusively) to valve support devices for use in the mitral valve position, the present invention also applies when stabilizing and anchoring elements are incorporated into any other intracardiac device of the aforementioned type. The presently...

Abstract

An intracardiac device comprising a ring-shaped body and one or more anchoring or stabilizing elements attached to said body, said elements being selected from the group consisting of levered anchoring arms, elongate anchoring arms, and lateral extension elements, wherein said device is able to move between two conformations, a collapsed conformation suitable for insertion into a delivery catheter, and an open conformation, suitable for implantation at a cardiac valve annulus.

Description

[0001] This application is a divisional application of a Chinese invention patent application (application number: 2014800160795, application date: January 16, 2014, invention name: anchoring element for intracardiac devices). technical field [0002] The present invention relates to stabilizing and anchoring elements for improving the stability of intracardiac devices. In particular, the present invention relates to the stabilization and anchoring of intracardiac devices within the mitral valve annulus. Background technique [0003] Heart valve regurgitation occurs when the heart valve leaflets do not close completely when the heart contracts, thereby allowing blood to flow back through the improperly closed leaflets. For example, mitral regurgitation occurs when blood flows back through the mitral valve and into the left atrium when the ventricles contract. [0004] Currently, organic regurgitation is achieved by attempting to remodel the natural valve leaflets (such as w...
