Abstract

A combination of a vascular prosthesis and retaining element, whereby a tubular retaining element (2) is arranged on at least one end of the vascular prosthesis (1), such that the above at least partly extends into the vascular prosthesis (1).

Claims

1. ) Combination of a vascular prosthesis and a retaining element, characterized in that a tubular retaining element (2) is arranged on at least one end of the vascular prosthesis (1) in such a manner that it projects at least partially into the vascular prosthesis (1).

2. ) The combination according to claim 1, characterized in that the retaining element (2) projects at least partially into the inner lumen of the vascular prosthesis (1).

3. ) The combination according to any one of the above claims, characterized in that the retaining element (2) is arranged in the vascular prosthesis (1) (internal retaining element (2)).

4. ) The combination according to one of the claims 1 or 3, characterized in that another retaining element (2) is arranged on one end external to the vascular prosthesis (1) (external retaining element (2)).

5. ) The combination according to claim 1 or 2, characterized in that the retaining element (2) projects distally out of the vascular prosthesis (1).

6. ) The combination according to claim 5, characterized in that the retaining element is arranged by more than 50% of its length within the vascular prosthesis (1).

7. ) The combination according to any one of the above claims, characterized in that one or several retaining elements (2) are arranged on one end (5) of the vascular prosthesis (1).

8. ) The combination according to any one of the above claims, characterized in that the vascular prosthesis (1) is an endoluminal vascular prosthesis (1).

9. ) The combination according to any one of the above claims, characterized in that the vascular prosthesis (1) is firmly connected with the retaining element(s) (2).

10. ) The combination according to any one of the above claims, characterized in that the vascular prosthesis (1) is made of PTFE or double Dacron velour.

11. ) The combination according to any one of the above claims, characterized in that the vascular prosthesis (1) has a tapering form.

12. ) The combination according to any one of the above claims, characterized in that the internal and/or external retaining element(s) (2) are compressible and radially expandable.

13. ) The combination according to any one of the above claims, characterized in that the retaining element(s) (2) primarily consist of one or several plastic materials and/or one or several metals of the group iron, tantalum, titanium, niobium, platinum or an alloy consisting of at least one of these metals combined with at least another metal, and, preferably, Nitinol.

14. ) The combination according to any one of the above claims, characterized in that at least one of the retaining elements is a stent (2).
