摘要: A method for making a graft layer is provided. The graft layer has at least two layers with different porosities. The two layers are applied by electrospinning. The parameters of the electrospinning may be varied when applying the first and second layers in order to achieve different porosities of the first and second layers.

摘要: A helical stent is provided that is wound in a zig-zag pattern along a pitch angle with respect to a plane transverse to the axis of the stent. A bisecting line extending through a bend and between two adjacent angular struts is also angled with respect to the longitudinal axis of the stent.
