Device for implantation in the heart of a mammal
First Claim
1. 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 comprisesa first tubular stent member, so dimensioned as to be implantable within the superior vena cava, and having a length, a diameter, a first end and a second end, wherein the first tubular stent member does not comprise a covering on an interior of the first tubular stent member or an exterior of the first tubular stent member,a second tubular stent member, so dimensioned as to be implantable within the inferior vena cava, and having a length, a diameter, a first end and a second end, wherein the said second tubular stent member does not comprise a covering on an interior of the second tubular stent member or an exterior of the second tubular stent member,a tubular stent graft member, having a length, a diameter, a first stent graft member end, a second stent graft member end, and an opening along the length, and comprising a covering being attached to a stent element, wherein the tubular stent graft member is fixedly assembled between the first tubular stent member and the second tubular stent member, such, that the second stent graft member end is attached to the first tubular stent member'"'"'s first end, and the first stent graft member end is attached to the second tubular stent member'"'"'s second end, wherein the tubular stent graft member is so dimensioned as to be implantable within the right atrium of the mammal'"'"'s heart;
- anda stented valve member comprising a stent element and a valve, the valve being mounted on the stent element, wherein the stent element of the stented valve member is fixedly mounted on the stent element of the tubular stent graft member such that the stent element of the stented valve member is sized and fitted to align with the opening of the tubular stent graft member, wherein the stented valve member is unidirectional, allowing blood to flow from the vena cava into the right atrium in a direction generally perpendicular to the lumen while blocking the blood flow in an opposite direction, wherein the stented valve member comprises a material that is selected from animal pericardium or from native leaflets from a human heart or veins, and wherein the valve is configured to function as a tricuspid valve of a human heart, to prevent regurgitation of a natural tricuspid valve when implanted.

Abstract
A device for implantation into the heart of a mammal and a method for treating tricuspid regurgitation using the device. The device includes two tubular stent members separated by a stent graft member which has a functional stented valve member attached thereto allowing unidirectional blood flow from the vena cava into the right atrium.
