## Abstract

A device for heart valve replacement comprises a valve component having at least two valve leaflets preferably made of pericardium tissue. Each valve leaflet includes at least two tabs. The device further includes a stent component configured to be radially compressible into a compressed state and expandable into a functional state. The stent component comprises a first end, a second end and at least one intermediate section arranged between said first and said second end. The intermediate section has at least two commissural posts generally aligned parallel to an axis spanning from the first end to the second end. The commissural posts are formed in the shape of a wishbone.

## Claims

### Claim 1

A valve replacement device for transcatheter implantation, comprising:
a stent component having an inflow extremity and an outflow extremity,
the stent component being radially compressible to a compressed state for delivery to a site of implantation and radially expandable to a functional state;
valve leaflets mounted at least partly within the stent component;
an inner skirt attached to the valve leaflets, the inner skirt extending at least partly within the stent component towards the inflow extremity; and
an outer skirt extending at least partly outside the stent component, the outer skirt extending further than the inner skirt towards the inflow extremity.
