14. A braided stent comprising:
-
a number of elongate filaments inter-braided to form a tubular wall, the filaments being inter-braided at a braiding angle formed at crossing filament locations; the tubular wall comprising a first portion having a first diameter, a second portion having a second diameter which is different from the second diameter and a transition portion positioned between the first portion and the second portion; wherein the braiding angles in the first portion, the braiding angles in the second portion, and the braiding angles in the transition portion are substantially equal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
