Abstract
Abstract A new stent graft comprises two coaxial, radially-expandable stents (11,12), between which a flexible, extensible layer of material (13) is located. Preferably this covers only a part of the stents. The stents preferably have terminal inter-bonding. The layer, preferably a sheet or fabric, comprises polytetrafluoroethylene or polyethylene terephthalate. It is a biological material, e.g. of autologous or homologous origin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
64 words
A stent graft comprising two coaxially arranged, radially
extendable stents, and a flexible, stretchable material
layer (13) being arranged between said stents (11, 12),
being characterized in that said stents (11, 12) are
punctually connected with one another in their end regions,
and that said material layer (13) is formed as a foil or
fabric band which is wound around the inner stent (11).
Claim 2
Dependent Claim
23 words
Stent graft according to claim 1, being characterized in
that said material layer (13) covers only a part of said
stents (11, 12).
Claim 3
Dependent Claim
29 words
Stent graft according to claim 1 or 2, being characterized
in that said material layer (13) is formed as a hose-shaped
element composed of a foil or a fabric.
Claim 4
Dependent Claim
22 words
Stent graft according to one of claims 1 to 3, being
characterized in that said material layer (13) is composed
of polythetrafluorethylene.
Claim 5
Dependent Claim
22 words
Stent graft according to one of claims 1 to 3 being
characterized in that said material layer (13) is composed
of polyethylenteraphtalate.
Claim 6
Dependent Claim
24 words
Stent graft according to one of claims 1 to 3, being
characterized in that said material layer (13) is composed
of a biological material.
