Abstract

An implantable prosthesis with at least one fenestration in a side wall of that prosthesis is disclosed. The fenestration provides an access port through which a medical device (such as a needle or a cannula) can be directed to enable access to the lumen of the blood vessel which the prosthesis is supporting.

Claims

1. An intraluminal device for use in accessing a vessel lumen with a medical implement, said device configured to support the wall of a vessel and comprising at least one device wall defining a device lumen to accommodate flow in said vessel lumen, wherein said device wall comprises at least one fenestration configured to allow access of the medical implement to the device lumen, wherein the at least one fenestration has a reinforced perimeter.

2. The device of claim 1, wherein said reinforced perimeter is reinforced along substantially the whole of the perimeter of the fenestration.

3. The device of claim 1, wherein said reinforced perimeter comprises a greater thickness of the material of the device than that which makes up the rest of the device.

4. The device of claim 1, wherein said reinforced perimeter comprises a frame disposed about the fenestration.

5. The device of claim 4, wherein the frame is expandable.

6. The device of claim 1, wherein said reinforced perimeter further comprises at least one marker suitable for locating said fenestration.

7. The device of claim 6, wherein said at least one marker is radiopaque.

8. The device of claim 1, wherein said device further comprises a cover that extends at least partially across said at least one fenestration.

9. The device of claim 8 wherein said cover is elastomeric.

10. The device of claim 1, wherein said device further comprises a guiding structure configured to guide a medical implement through the fenestration.

11. The device of claim 1, wherein said fenestration is elongate in the direction in which the device lumen extends.

12. The device of claim 1, wherein the wall of the device has a reinforced portion opposing the fenestration.

13. The device of claim 12, wherein the reinforced portion comprises a higher density of struts in the reinforced region than outside of the reinforced region.

14. The device of claim 1, wherein said device has two fenestrations spaced in the direction in which the device lumen extends.

15. The device of claim 1, wherein the device carries a drug for release in the vessel.

16. A method of facilitating future access to a lumen of a vessel in a body with a medical implement, said method comprising the steps of:

providing an intraluminal device configured to support the wall of the vessel, said device comprising at least one device wall defining a device lumen to accommodate flow in said vessel lumen, wherein said device wall comprises at least one fenestration configured to allow access of the medical implement to the device lumen; and

inserting said device into a body vessel such that the fenestration is accessible percutaneously with said medical implement.

17. The method of claim 16, comprising the step of inserting two like intraluminal devices in the vessel, one to withdraw blood from and one to introduce blood to the vessel.

18. A method of accessing a lumen of a body vessel with a medical implement, said method comprising the steps of:

locating an intraluminal device which has previously been implanted in said vessel, said intraluminal device configured to support the wall of the vessel, said device comprising at least one device wall defining a device lumen to accommodate flow in said vessel lumen, wherein said device wall comprises at least one fenestration configured to allow access of the medical implement to the device lumen;

locating said fenestration in said device wall; and

accessing the lumen of the device via said fenestration with a medical implement.

19. A method of accessing a lumen of a vein in a body with a medical implement, said method comprising the steps of creating a fistula between said vein and an artery in said body and implanting an intraluminal device in said lumen of said vein in or proximal to the fistula, wherein said intraluminal device is configured to support the wall of the vein, said device comprising at least one device wall defining a device lumen to accommodate flow in said vein lumen, wherein said device wall comprises at least one fenestration configured to allow access of the medical implement to the device lumen, and wherein access to the lumen of said vein is achievable via said fenestration.
