Atraumatic stent and method and apparatus for making the same

摘要

A method of braiding a stent and associated braided stent. The method includes braiding a number of elongate filaments around a mandrel using tensioned braiding carriers without spooling the filaments to the tensioned braiding carriers to form a braided stent having atraumatic ends. The braided stent includes a plurality of filaments being inter-braided at a braiding angle formed at crossing filament locations. The braiding angle may be substantially constant for all of the filament crossing locations.
