Abstract

The invention relates to a heart valve prosthesis comprising biological material or plastic material, having a suture or knot which comprises an X-ray visible material and the position of which identifies the valve plane.

Claims

1. A heart valve prosthesis made of biological material or plastic material, having a suture section including at suture or knot which comprises an X-ray visible metal wire wherein a position of the suture section identifies a plane of the heart valve prosthesis.

2. The heart valve prosthesis according to claim 1, wherein the metal wire comprises or is coated with at least one of the elements gold, platinum, tantalum and tungsten.

3. A heart valve prosthesis according to claim 1, wherein the metal wire has a diameter ranging between about 20 and about 200 μ

m.

4. A heart valve prosthesis according to claim 1, wherein the suture has a portion produced from a different suture material.

5. A heart valve prosthesis according to claim 1, wherein the suture comprises a double suture, an overlap suture, or an overlock suture.

6. A heart valve prosthesis according to claim 1, wherein the heart valve prosthesis comprises a base body, and three valvular cusps, each valvular cusp having the suture section.

7. A heart valve prosthesis according to claim 6, wherein the valvular cusps are sewn into the base body with the suture.

8. A heart valve prosthesis according to claim 1, wherein the suture is placed such that a predefined end thereof identifies a position of the valve plane.

9. A heart valve prosthesis according to claim 1, wherein the suture section includes the knot.

10. A heart valve prosthesis according to claim 1, which is sewn into a vascular stent, wherein a suture connecting the heart valve prosthesis to the vascular stent is arranged in a corresponding manner to a position of the valve plane and is produced from the X-ray visible metal wire.

11. A heart valve prosthesis according to claim 1, which is sewn into a vascular stent, wherein the vascular stent has a suture section which comprises the X-ray visible metal wire and a position of the suture section of the vascular stent identifies the valve plane.

12. A heart valve prosthesis according to claim 1, wherein the metal wire has a diameter ranging between about 50 and about 100 μ

m.

13. A heart valve prosthesis made of biological material or plastic material, the heart valve prosthesis comprising a base body, and three valvular cusps, each valvular cusp having a suture section including at suture or knot which comprises an X-ray visible metal wire, the valvular cusps being sewn into the base body with the suture, wherein a position of the suture sections identifies a plane of the heart valve prosthesis.

14. The heart valve prosthesis according to claim 13, wherein the metal wire comprises or is coated with at least one of the elements gold, platinum, tantalum and tungsten.

15. A heart valve prosthesis according to claim 13, wherein the metal wire has a diameter ranging between about 20 and about 200 μ

m.

16. A heart valve prosthesis according to claim 13, wherein the suture has a portion produced from a different suture material.

17. A heart valve prosthesis according to claim 13, wherein the suture comprises a double suture, an overlap suture, or an overlock suture.

18. A heart valve prosthesis according to claim 13, wherein the suture is placed such that a predefined end thereof identifies a position of the valve plane.

19. A heart valve prosthesis according to claim 13, which is sewn into a vascular stent, wherein a suture connecting the heart valve prosthesis to the vascular stent is arranged in a corresponding manner to a position of the valve plane and is produced from the X-ray visible metal wire.

20. A heart valve prosthesis according to claim 13, which is sewn into a vascular stent, wherein the vascular stent has a suture section which comprises the X-ray visible metal wire and a position of the suture section of the vascular stent identifies the valve plane.
