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 woven, self-expanding stent device configured for insertion into an anatomical structure, the device comprising: a plurality of strands woven together to form a stent body, each of said plurality of strands having two strand end portions;a coupling structure coupled to a pair of strand end port
1. A woven, self-expanding stent device configured for insertion into an anatomical structure, the device comprising: a plurality of strands woven together to form a stent body, each of said plurality of strands having two strand end portions;a coupling structure coupled to a pair of strand end portions that are aligned end-to-end, the pair of strand end portions comprising strand end portions from a same strand or two different strands;wherein the pair of strand end portions includes nickel and titanium, and the coupling structure is not a strand of the device, andwherein the coupling structure is secured to a first strand end portion of the pair of strand end portions by a first weld that forms a first welded region, the coupling structure is secured to a second strand end portion of the pair of strand end portions by a second weld that forms a second welded region, and the first and second welded regions are not directly connected to each other along a longitudinal axis of the coupling structure by another welded region. 2. The device of claim 1, where the coupling structure has a passageway in which the pair of strand end portions are positioned. 3. The stent of claim 2, wherein the passageway has a diameter sized to receive one said strand. 4. The device of claim 1, wherein the device includes two or three device ends, where each device end is defined by strand bends. 5. The device of claim 1, where each said strand end portion is secured to only one other said strand end portion. 6. The device of claim 1, where the coupling structure is positioned beneath a strand of the device such that the strand is positioned radially outward from the coupling structure. 7. The device of claim 1, where the device includes two or three device ends and a longitudinal axis, the coupling structure is nearer to one of the device ends than any other device end, and the coupling structure is spaced apart from the nearest device end along a line substantially parallel to the longitudinal axis by at least one strand crossing. 8. The device of claim 1, where the coupling structure is laser welded to the first strand end portion of the two strand end portions. 9. The device of claim 8, where the coupling structure is laser welded to the second strand end portion of the two strand end portions. 10. The device of claim 1, further comprising: a second coupling structure coupled to another pair of strand end portions. 11. The device of claim 1, further comprising: one coupling structure coupled to each of five other pairs of strand end portions. 12. The device of claim 11, where the coupling structures are aligned with each other along an axis parallel to a longitudinal axis of the device. 13. The device of claim 1, further comprising: one coupling structure laser welded to each of five other pairs of strand end portions of the device, where each coupling structure includes nickel and titanium, and each strand end portion includes nickel and titanium. 14. The device of claim 13, where one of the five other pairs of strand end portions comprises strand end portions of two different strands of the device. 15. The device of claim 13, where one of the five other pairs of strand end portions comprises strand end portions of the same strand of the device. 16. The device of claim 13, where the coupling structures are aligned with each other along an axis parallel to a longitudinal axis of the device. 17. A self-expanding stent comprising: a multiple number of strands each including a first end and a second end, the strands being plain woven to form a stent having a proximal end and a distal end, wherein each of the strands is bent at both the proximal end of the stent and the distal end of the stent, and wherein the first end of each of the strands is aligned end-to-end with a second end of the same or a different strand to form a strand end pair; anda multiple number of tubular coupling structures, the number of tubular coupling structures equal to the number of strands, the tubular coupling structures being different than the strands, each of the tubular coupling structures secured to one of the strand end pairs, wherein each of the tubular coupling structures includes a passageway having a diameter sized to receive one said strand. 18. The stent of claim 17, wherein each of the tubular coupling structures is welded to each strand end of a strand end pair. 19. The stent of claim 17, wherein the tubular coupling structures are longitudinally spaced from each of the proximal and distal ends of the stent by at least two strand crossings. 20. The stent of claim 17, wherein the first end and the second end are spaced from each other in each said strand end pair. 21. The stent of claim 17, wherein the strands comprise Nitinol. 22. The stent of claim 21, wherein the tubular coupling structures comprise Nitinol. 23. The stent of claim 17, wherein the tubular coupling structure comprises a hollow tube. 24. The stent of claim 17, wherein the tubular coupling structure comprises an arcuate strip. 25. The stent of claim 17, wherein the tubular coupling structures are aligned with each other along an axis parallel to a longitudinal axis of the stent.
