Claims8
A vascular prosthesis comprising:
- a first layer, made of electrospun polymer fibers and having a predetermined first porosity,
- a second layer, made of electrospun polymer fibers and having a predetermined second porosity being higher than said predetermined first porosity, and
- at least one intermediate layer, made of electrospun polymer fibers and being interposed between said first layer and said second layer;
- wherein the electrospun polymer fibers of at least one of said first layer and said second layer are oriented predominantly transversely, and the electrospun polymer fibers of at least one of said at least one intermediate layer are oriented randomly.
