Abstract

An intraparietal reinforcement device (1) for use in a biological prosthesis (10), as well as a biological prosthesis (10) provided with a device of this type, is particularly suitable for use within the organic tissue of the biological prosthesis (10), and for reinforcing the structure of the prosthesis so that it retains its shape once implanted.

Claims

1. Intraparietal reinforcement valve (1) that is designed to be integrated into a biological prosthesis (10), characterized by the fact that it is suitable for being placed inside the organic tissue of this biological prosthesis (10) and for reinforcing the structure of the latter so as to keep its shape after implantation.

2. Intraparietal reinforcement device (1) according to claim 1, wherein it comprises an intraparietal rod (2) that is suitable for being inserted into the organic tissue of biological prosthesis (10) and a leg (3) that is attached to a first end of rod (2).

3. Intraparietal reinforcement device (1) according to claim 2, wherein it comprises in addition an attachment (4) that is suitable for being attached to a second end of rod (2).

4. Intraparietal reinforcement device (1) according to claim 2, wherein intraparietal rod (2) is straight.

5. Intraparietal reinforcement device (1) according to claim 2, wherein intraparietal rod (2) has a helical shape.

6. Intraparietal reinforcement device (1) according to claim 2, wherein rod (2) comprises a helical portion (2a) on its surface.

7. Intraparietal reinforcement device (1) according to claim 2, wherein rod (2) comprises at the second end a pointed portion (2b) that is suitable for piercing and penetrating, without causing damage, the organic tissue of biological prosthesis (10).

8. Intraparietal reinforcement device (1) according to claim 2, wherein leg (3) is made by a straight bar.

9. Intraparietal reinforcement device (1) according to claim 2, wherein leg (3) is made by a curved bar, whereby the curvature corresponds to the curvature of the outside circumference of biological prosthesis (10).

10. Intraparietal reinforcement device (1) according to claim 3, wherein attachment (4) is made by a curved bar, whereby the curvature corresponds to the curvature of the outside circumference of biological prosthesis (10).

11. Biological prosthesis (10), wherein it is provided with at least one intraparietal reinforcement device (1) according to claim 1.

12. Biological prosthesis (10) according to claim 11, wherein it involves an animal aortic valve that comprises intraparietal reinforcement devices (1).

13. Biological prosthesis (10) according to claim 12, wherein intraparietal rod (2) of intraparietal reinforcement devices (1) is placed inside tubular outside wall (12) of the valve along lines of intersection of this wall (12) with commissures (13) of the valve.

14. Biological prosthesis (10) according to claim 13, wherein leg (3) and/or attachment (4) of intraparietal reinforcement devices (1) are/is covered by a Teflon material.

15. Intraparietal reinforcement device (1) according to claim 3, wherein intraparietal rod (2) is straight.

16. Intraparietal reinforcement device (1) according to claim 3, wherein intraparietal rod (2) has a helical shape.

17. Intraparietal reinforcement device (1) according to claim 3, wherein rod (2) comprises a helical portion (2a) on its surface.

18. Intraparietal reinforcement device (1) according to claim 4, wherein rod (2) comprises a helical portion (2a) on its surface.

19. Intraparietal reinforcement device (1) according to claim 5, wherein rod (2) comprises a helical portion (2a) on its surface.

20. Intraparietal reinforcement device (1) according to claim 3, wherein rod (2) comprises at the second end a pointed portion (2b) that is suitable for piercing and penetrating, without causing damage, the organic tissue of biological prosthesis (10).
