Abstract

An aorta graft device comprising a primary graft part having a proximal end and a first connecting portion at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening. Furthermore, the ascending portion is corrugated, and the descending portion is at least partially non-corrugated.

Claims

1. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, and wherein the descending portion is at least partially non-corrugated.

2. An aorta graft device according to claim 1, wherein the descending portion of the primary graft part is non-corrugated at least at said first connecting means, and preferably along its full length from said anchoring area to said distal opening.

3. An aorta graft device according to claim 1, wherein the descending portion of the primary graft part is provided with at least one stent, and preferably provided with at least two stents, which are located near the anchoring area and at the distal opening, respectively.

4. An aorta graft device according to claim 1, wherein the descending portion of the primary graft part is supported by stent at least along the majority of its length.

5. An aorta graft device according to claim 1, wherein said anchoring area comprises an annular area encircling the primary graft part.

6. An aorta graft device according to claim 1, wherein the graft device includes a secondary graft part with a second connecting means that by engagement with said first connecting means connects said secondary graft part to said primary graft part.

7. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated, wherein the descending portion of the primary graft part is provided with at least one stent, and preferably provided with at least two stents, which are located near the anchoring area and at the distal opening, respectively, and wherein the descending portion of the primary graft has a distal end area which is uncorrugated and unstented and has a length of at least 20 mm.

8. An aorta graft device according to claim 7, wherein said ascending portion has a length in the range from 11 to 17 cm, wherein said descending portion has a stented length in the range from 5 to 10 cm, and wherein said distal end area has a length in the range from 2 to 3 cm.

9. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated and wherein at least the ascending portion of the primary graft part is precurved.

10. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated and wherein the ascending portion a wedge-shaped area of graft side wall has been removed and the exposed opposite rim areas joined to each other.

11. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated and wherein said anchoring area comprises an annular area that is uncorrugated, unstented and has a length of at least 10 mm.

12. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated, wherein said anchoring area comprises an annular area encircling the primary graft and wherein said anchoring area includes a lateral area extending away from the annular area in direction of the ascending portion.

13. An aorta graft device according to claim 12, wherein said lateral area is carrying a marking.

14. An aorta graft device according to claim 12, wherein said lateral area includes a lateral opening.

15. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated and wherein a mounting state of said primary graft part the ascending portion has been everted into said descending portion to present said annular anchoring area as a rim area.

16. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated and wherein the graft device includes an end portion with a heart valve.

17. An aorta graft device according to claim 16, wherein the primary graft part has a proximal opening, and wherein the end portion with the heart valve is a separate part to be fixed to said primary graft part at said proximal opening.

18. An aorta graft device comprising a primary graft part having a proximal end and a first connecting means at a distal opening, wherein the primary graft part has an anchoring area positioned between an ascending portion extending to said proximal end and a descending portion extending to said distal opening, wherein the ascending portion is corrugated, wherein the descending portion is at least partially non-corrugated and wherein the engagement involves geometrically interlocking parts on said first and second connecting means, respectively, whereby the engagement is enhanced when said secondary graft part is pulled in the distal direction.
