A method of forming a self-expanding stent, the method comprising:
- forming a first end of the stent by forming a first bend in each of a plurality of strands, each strand including a strand section on both sides of the first bend, each strand section including an end;
- weaving the strand sections;
- after weaving the strand sections, heat treating the plurality of strands for a first heat treatment time;
- forming a second end of the stent by forming a second bend in each of the plurality of strands;
- and
- after forming the second bends, back braiding some of the strand sections, wherein back braiding some of the strand sections comprises passing the strand sections by at least two strand crossings,
- wherein passing the strand sections by at least two strand crossings comprises passing the strand sections radially inward of at least one strand crossing and radially outward of at least one other strand crossing.
