Abstract

An apparatus for stabilizing a prosthetic heart valve within an atrioventricular valve includes a collapsible and expandable stent having an inflow end, an outflow end, and struts forming a plurality of cells connected to one another in a plurality of annular rows around the stent. The stent further includes a collapsible and expandable valve assembly secured to the stent. The valve assembly includes a cuff and a plurality of leaflets having an open configuration and a closed configuration. A cord connected to the stent includes an attachment device adapted to couple the stent to heart tissue of a patient. A method of stabilizing a prosthetic heart valve within an atrioventricular valve annulus is also described.

First claim

The invention claimed is:

1. A prosthetic heart valve, comprising:
a collapsible and expandable stent having an inflow end and an outflow end, the stent including struts forming a plurality of cells, the plurality of cells being connected to one another in a plurality of annular rows around the stent;
a collapsible and expandable valve assembly secured to the stent, the valve assembly including a cuff and a plurality of leaflets having an open configuration and a closed configuration;
a cord connected to the stent;
an attachment device operatively connected to the cord;
a bridge adapted to be coupled between a first papillary muscle and a second papillary muscle of the heart; and
a sliding clamp coupled to the bridge configured to adjust tension of the bridge;
wherein the cord is connected to the bridge via the attachment device.

2. The apparatus of claim 1 , wherein the attachment device is selected from the group consisting of clasps, barbs, coils or combinations thereof configured to couple the stent to the papillary muscles of the patient.

3. The apparatus of claim 1 , wherein the sliding clamp is configured to modify a shape of a left ventricle of the heart.

4. The apparatus of claim 1 , wherein the bridge includes a first clasp configured to attach to the first papillary muscle and a second clasp configured to attach to the second papillary muscle.
