A method of braiding a stent 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.

Atraumatic stent and method and apparatus for making the same

A stent includes a mesh wall including a plurality of filament crossings, the mesh wall defining at least a first stent section with a first diameter, a second stent section with a second diameter smaller than the first diameter, and a transition section where the mesh wall transitions from the second diameter to the first diameter. Each of the plurality of filament crossings has a braiding angle, and all braiding angles in each of the first stent section, the second stent section and the transition section are within 5 degrees of one another.

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.
