Abstract

A method for implanting a medical set in a human blood vessel, the medical set comprising a prosthesis adapted to be introduced in the vessel, the prosthesis having a first end and a second end, and being adapted to be disposed against an inner wall of the vessel at least at one of the ends, the prosthesis comprising a tubular sleeve and a strap adapted to be disposed against the vessel at a location adjacent one of the ends of the tubular sleeve, the strap having a hemostatic covering for reducing any blood leakage at the location of the strap.

Claims

1. A medical set for a duct in a human body, comprising:

a stent graft adapted to be introduced in the duct, the stent graft comprising a tubular sleeve and stent means,

a strap adapted to surround the exterior of the duct, at a location adjacent the stent graft, the strap comprising a rigid structure which is deformable, the rigid structure comprising two hoopings which are substantially parallel and spaced one from the other.

2. The medical set of claim 1, wherein the rigid structure is deformable between a first position in which it has an opened ring shape showing a ring opening having a determined width and a second position in which said width is enlarged.

4. The medical set according to claim 2, wherein the two hoopings have naturally a split ring shape, each.

5. The medical set according to claim 2, wherein the strap is elastically deformable between a first relaxed position in which the rigid structure has said naturally opened section ring and a second constrained position.

6. The medical set according to claim 5, further comprising a tubular catheter for introducing the strap in the human body round the duct, the tubular catheter having an internal diameter adapted for receiving the strap in its second constrained position.

7. The medical set according to claim 6, further comprising pliers for grasping the strap, the pliers being adapted for being slidably disposed in the tubular catheter, together with the strap.

9. The medical set according to claim 6, wherein, in the tubular catheter, the strap is constrained in its second constrained position which is a substantially flat-shaped position.

10. The medical set according to claim 2, wherein the two hoopings have free ends and are connected one to the other at said ends.

11. The medical set according to claim 2, wherein the rigid structure is covered with a protective layer made of a self-sealing material.

12. The medical set according to claim 11, wherein the self-sealing material is a silicone.

13. The medical set according to claim 2, wherein the rigid structure is covered with an hemostatic pledget.

14. The medical set according to claim 11, wherein the protective layer is covered with an hemostatic pledget.

15. The medical set according to claim 13, wherein the duct has an outer section and the hemostatic pledget has a length and a first end and a second end, where divisible members extend, to fit the length of the strap to the outer section of the duct.

16. The medical set according to claim 15, wherein the divisible members are made of one of felt and cloth.

3. A medical set for a duct in a human body, the medical set comprising a strap adapted to surround the duct, the strap comprising a rigid structure which is deformable, the rigid structure having a naturally opened section ring shape comprising two hoopings which are spaced one from the other.

8. The medical set, wherein the strap has an hemostatic covering for reducing a blood leakage at the location of the strap.

17. A medical set for a duct in a human body, comprising a strap adapted to surround the duct, the strap comprising a rigid structure defining a radio-opaque marker.

18. The medical set of claim 17, wherein the rigid structure is deformable and has a naturally opened section ring shape.

19. The medical set of claim 17, wherein the rigid structure comprises two blades defining two radio-opaque markers which are spaced one from the other.

20. The medical set of claim 17, wherein the rigid structure is deformable between a first position in which it has an opened ring shape showing a ring opening having a determined width and a second position in which said width is enlarged.
