Abstract
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.
Claims20
A method of making a stent comprising:
- securing an intermediate portion of each of a plurality of filaments around a respective securement projection at a first end region of a mandrel;
- and
- braiding the plurality of filaments along a cylindrical body of the mandrel toward a second end of the mandrel, wherein the mandrel includes a plurality of helical grooves defined between adjacent raised projections positioned along the cylindrical body of the mandrel, wherein braiding includes disposing the plurality of filaments into the plurality of grooves.
A method of making a stent comprising:
- securing an intermediate portion of each of a plurality of filaments around a respective securement projection at a first end region of a mandrel, the intermediate portions of the filaments defining a first end of the stent;
- braiding the plurality of filaments along a cylindrical body of the mandrel toward a second end of the mandrel, wherein the mandrel includes a plurality of helical grooves defined between adjacent raised projections positioned along the cylindrical body of the mandrel, wherein braiding includes disposing the plurality of filaments into the plurality of grooves;
- and
- forming closed loops with the filaments at the second end of the mandrel, the closed loops defining second end of the stent;
- wherein the stent includes a flared region at the first end of the stent, the flared region having a larger diameter than a body of the stent.
