1. A device for implantation in the heart of a mammal, with a generally tubular shape, and having a longitudinal axis, a first end and a second end, and a lumen permitting blood flow there through, wherein the device comprises;
a first tubular stent member, sized and configured for implantation within the superior vena cava, and having a length, a diameter, a first and a second end; a second tubular stent member, sized and configured for implantation within the inferior vena cava, and having a length, a diameter, a first and a second end, wherein the said second tubular stent member does not comprise a covering; a tubular stent graft member, having a length, a diameter, a first and a second stent graft member end, and comprising a covering being attached to a stent element, wherein the tubular stent graft member is fixedly assembled between the first and the second tubular stent members, such, that the second stent graft member end is attached to the first stent member's first end, and the first stent graft member end is attached to the second stent member's second end, wherein the stent graft member is sized and configured for implantation within the right atrium of the mammal's heart; and a stented valve member comprising a stent element and a valve, the valve being mounted on the stent element, wherein the stented valve member is fixedly mounted on the stent graft member, wherein the valve member is unidirectional, allowing blood to flow from the vena cava into the right atrium while blocking the blood flow in the opposite direction. |
