Benefits of technology

The invention is a medical device and method for repairing and replacing valves. It also includes an annuloplasty device that can be easily attached to the valve annulus. These improvements make the process more effective and durable.

Problems solved by technology

The mitral and tricuspid valve leaflets or supporting chordae may degenerate and weaken or the annulus may dilate leading to valve leak, i.e. an insufficiency of valve function.
The leaflets and chords may become calcified and thickened rendering them stenotic, which implies obstructing a forward flow through the valve.
If the ventricle changes in shape, the valve support may become non-functional and the valve may leak.
Paravalvular leakage is another issue that is however not addressed in these disclosures.

Embodiment Construction

[0088]Specific embodiments of the invention will now be described with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, like numbers refer to like elements.

[0089]FIG. 1A illustrates a patient 10 having a heart 12 shown in cross-section including a left ventricle 14 and a right ventricle 16. The concepts of the present invention are suitable to be applied, for example, to a mitral valve 18, which supplies blood into left ventricle 14. Mitral valve 18, as better shown in FIG. 1B, includes an annulus 20 and a pair o...

Abstract

A device for improving the function of a heart valve comprises a first loop-shaped support, which is configured to abut a first side of the heart valve. A first flange unit is may be configured as a fabric sleeve covering the loop-shaped support. A portion of the fabric sleeve forms a flange that is attached to the annulus when said first loop-shaped support is abutting said heart valve. The flange is provideable by folding at least a portion of said sleeve over itself for forming a double layer of opposing fabrics thereof, such that said sleeve comprises a flange portion extending from said first loop-shaped support configured to overlap a surface of and form a collar around, at least a portion of said annulus.

Description

FIELD OF THE INVENTION[0001]The present invention pertains in general to the field of fixation of medical devices, such as implants to body tissue at a patient. Some particular examples are related to repair or replacement of heart valves having various malformations and dysfunctions. More specifically, some aspects of the invention relate to or are useful in heart valve repair techniques and / or medical procedures involving annuloplasty devices.BACKGROUND OF THE INVENTION[0002]Medical devices frequently need to be fixated to body parts of a patient.[0003]For instance, diseased mitral and tricuspid valves frequently need replacement or repair. The mitral and tricuspid valve leaflets or supporting chordae may degenerate and weaken or the annulus may dilate leading to valve leak, i.e. an insufficiency of valve function. The leaflets and chords may become calcified and thickened rendering them stenotic, which implies obstructing a forward flow through the valve. Finally, the valve relie...
