Woven stent device and manufacturing method

A medical device in the form of a woven stent comprising:

• a body defined by a plurality of wires extending in a first helical direction around the body and extending in a second helical direction around the body, the second helical direction being transverse to the first helical direction;
• wherein the plurality of wires are woven together to define a plurality of cells and a plurality of intersections;
• a first crown portion of the stent disposed at a first end of the stent and defined by a first wire end portion of the plurality of wires, the first crown portion including a curvilinear bend portion defining an apex of the first crown portion, wherein the first wire end portion extends in the first helical direction toward the apex of the crown and bends at the apex of the first crown portion, and further extends from the apex of the first crown portion and is woven into the stent in the second helical direction, wherein the first wire end portion terminates at a first wire free end that is disposed longitudinally inward of a longitudinally outermost intersection of the plurality of intersections;
• and
• a second crown portion of the stent disposed at the first end of the stent and defined by a second wire end portion of the plurality of wires, the second crown portion including a curvilinear bend portion defining an apex of the second crown portion, wherein the second wire end portion extends in the second helical direction toward the apex of the second crown portion and bends at the apex of the second crown portion, and further extends from the apex of the second crown portion and is woven into the stent in the first helical direction, wherein the second wire end portion terminates at a second wire free end that is disposed longitudinally inward of the longitudinally outermost intersection of the plurality of intersections,
• wherein the first and second crown portions overlap each other to define a double crown.
