Abstract

The present invention relates to a medical apparatus for the therapeutic treatment of an insufficient cardiac valve (3a, 3b). The aim of the present invention is to specify a medical apparatus which enables the therapeutic treatment of an insufficient cardiac valve, such as, for example, the mitral valve (3a) or the tricuspid valve (3b), which is arranged between a ventricle (1a, 1b) and an atrium (2a, 2b) of the heart, in a manner as simple as possible and as gentle as possible for the patient in a minimally invasive intervention. For this purpose, the medical apparatus according to the present invention comprises at least one valve means (10) which is designed to prevent in the implanted condition of the medical apparatus a systolic venous reflex return of blood from the atrium (2a, 2b) of the heart into at least one vein (4a, 4a′, 4b, 4b′, 4c, 4c′) which belongs to a venous system (4) which leads into the atrium (2a, 2b) of the heart.

Claims

1. An apparatus for treating regurgitation deficiencies of an atrioventricular valve located between a ventricle of a heart and an atrium of the heart, comprising:

a first stent, having a first valve attached thereto, for implantation at least partially within a first vein leading to the atrium;

a second stent, having a second valve attached thereto, for implantation at least partially within a second vein leading to the atrium;

a third stent, having a third valve attached thereto, for implantation at least partially within a third vein leading to the atrium; and

a fourth stent, having a fourth valve attached thereto, for implantation at least partially within a fourth vein leading to the atrium;

wherein the first stent is structurally unconnected from the second stent, and the third stent is structurally unconnected from the fourth stent.

2. The apparatus of claim 1, wherein

the first and third valves permit blood flow towards the atrium from the first and third veins, respectively, and prevent blood flow from the atrium to the first and third veins, respectively, when implanted;

and

the second and fourth valves permit blood flow towards the atrium from the second and fourth veins, respectively, and prevent blood flow from the atrium to the second and fourth veins, respectively, when implanted.
