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.
1. A method of forming a self-expanding stent, the method comprising: bending each of a multiple number of strands to yield first strand bends and strand portions on both sides of each said first strand bend, each of the strand portions having an end;weaving the strand portions, wherein weaving comp
1. A method of forming a self-expanding stent, the method comprising: bending each of a multiple number of strands to yield first strand bends and strand portions on both sides of each said first strand bend, each of the strand portions having an end;weaving the strand portions, wherein weaving comprises bending to yield second strand bends and back braiding some of the strand portion ends by at least two strand crossings; andsecuring each of a multiple number of coupling structures to one pair of said strand portion ends, the pair of said strand portion ends including two strand portion ends of two different strands or the same strand, the number of coupling structures equal to the number of strands, the coupling structures being different than the strands, wherein securing comprises aligning the pairs of strand portion ends end-to-end. 2. The method of claim 1, further comprising heat treating the stent before back braiding. 3. The method of claim 1, further comprising heat treating the stent after back braiding. 4. The method of claim 1, wherein weaving the strand portions comprises machine weaving. 5. The method of claim 1, wherein back braiding some of the strand portion ends comprises hand weaving. 6. The method of claim 1, wherein securing comprises welding the strand ends to the coupling structures. 7. The method of claim 1, further comprising, after weaving, trimming the strand portions.
