Abstract

A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

Claims

1. An apparatus for treating mitral annulus dilatation of a heart, the apparatus comprising:

a proximal anchor configured to be positioned in and fixed in the heart;

a distal anchor configured to be positioned in and fixed in the heart distally of the proximal anchor; and

a drawing member joined to the distal anchor and extending proximally from the distal anchor through a coronary sinus of the heart to the proximal anchor to draw the distal anchor towards the proximal anchor;

wherein, in a first position, the proximal and distal anchors are configured to be fixed in the heart at a first distance apart from each other and the drawing member extends proximally of the proximal anchor and, in a second position, the proximal and distal anchors are configured to be fixed in the heart at a second distance closer together than in the first position.

2. The apparatus of claim 1 wherein the proximal anchor comprises a proximal stent section and the distal anchor comprises a distal stent section.

3. The apparatus of claim 2 wherein the proximal and distal stent sections are expandable from a reduced size configuration to an expanded configuration.

4. The apparatus of claim 1, wherein the drawing member is maneuverable from outside the vein system.

5. The apparatus of claim 1, wherein the drawing member is secured to the proximal anchor in the second position.

6. The apparatus of claim 1, wherein the drawing member is slidable relative to the proximal anchor.

7. The apparatus of claim 1, wherein the drawing member is a wire.
