Benefits of technology

"The present invention is about a device and method for repairing a damaged mitral valve. The device includes an elongate tension member with two ends. The first end has a basal anchor, which can be an artificial heart valve or an annuloplasty ring, and the second end has a secondary anchor, which can be a hook-shaped papillary muscle tissue loop, screw-shaped tissue anchor, or transmural anchor pad. The tension member is placed in the left ventricle chamber to improve heart function. The method involves using one or more tension members to alter the geometry of the heart and reduce wall stress. This invention can be used to treat chronic heart failure and improve mitral valve function."

Problems solved by technology

First, chamber dilation and associated high wall stresses increase the diameter of the mitral valve annulus.

Embodiment Construction

[0033] Referring now the drawings wherein like reference numerals refer to like elements throughout the several views, FIG. 1 shows a transverse cross section of the left ventricle 10 of a failing heart taken from FIG. 2. The papillary muscles 12 are shown in cross section. FIG. 2 is a vertical cross section of human heart 10. A mitral valve is disposed near the top of left ventricle 10. Mitral valve 14 includes two leaflets or cusps 16. Chordae 18 extend between leaflets 16 and papillary muscles 12.

[0034]FIG. 3 is a cross section of heart 10 modified from that shown in FIG. 1 by placement of valve repair device 20 in accordance with the present invention as shown in FIG. 4. FIG. 4 is a vertical cross section of left ventricle 10 with geometry modified by device 20. In this embodiment of the invention, device 20 includes a basal anchor 22 such as an annuloplasty or suture ring sewn proximate the annulus of valve 14. Extending from basal anchor 22 are elongate tension members 24. Ea...

Abstract

A device for heart valve repair including at least one tension member having a first end and second end. A basal anchor is disposed at the first end of the tension member and a secondary anchor at the second end. The method includes the steps of anchoring the basal anchor proximate a heart valve and anchoring the secondary anchor at a location spaced from the valve such that the chamber geometry is altered to reduce heart wall tension and / or stress on the valve leaflets.

Description

BACKGROUND OF THE INVENTION [0001] The present invention pertains generally to the field of heart valve repair. More specifically, the present invention pertains to a device and method for the reduction of myocardial wall tension and the repair of mitral valve insufficiency. [0002] Dilated cardiomyopathy is often accompanied by mitral valve insufficiency. There are several reasons for the presence of mitral valve insufficiency associated with a dilated heart. First, chamber dilation and associated high wall stresses increase the diameter of the mitral valve annulus. Additionally, as the heart dilates, the positioning of the papillary muscles is altered. Papillary muscles and chordae in a dilated heart will have moved both radially away and down from the mitral valve. This rearrangement of the vascular apparatus and enlargement of the annulus prevent the valve from closing properly. [0003] Currently mitral valve insufficiency is treated by either repairing or replacing the valve. Sur...
