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.

43. 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. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51)

52. A valve replacement device for transcatheter implantation, comprising:
-
a stent component comprising a first end, a second end and at least one intermediate section arranged between the first end and the second end, the stent component being radially compressible to a compressed state for delivery to a site of implantation and radially expandable to a functional state, the intermediate section comprising at least two commissural posts each in the shape of a wishbone including a stem communicating with adjacent stent structure and two legs communicating with adjacent stent structure, and at least two valve leaflets supported by the stent component, each valve leaflet including at least two tabs directly attached to the commissural posts. - View Dependent Claims (53, 54, 55, 56)

57. A valve replacement device for transcatheter implantation, comprising:
-
a stent component comprising a first end, a second end and at least one intermediate section arranged between the first end, and the second end, the stent component being radially compressible to a compressed state for delivery to a site of implantation and expandable to a functional state, the intermediate section comprising at least two commissural posts; an inner skirt extending at least partly within the interior of the stent component; and at least two valve leaflets each including at least two tabs, the tabs projecting through slits in the inner skirt and attached directly to the commissural pots. - View Dependent Claims (58, 59, 60, 61, 62, 63)
