Abstract
A woven, self-expanding stent device has one or more strands and is configured for insertion into an anatomical structure. The device includes a coupling structure secured to two different strand end portions that are substantially aligned with each other. The two different strand end portions include nickel and titanium. The coupling structure is not a strand of the device.
Claims23
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;
- heat treating the plurality of strands for a second heat treatment time;
- and
- securing each of the strand section ends to another of the strand section ends to form pairs of secured ends, wherein securing the pairs of secured ends comprises aligning the pairs of secured ends along an axial direction of the stent.
