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.
Claims25
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, and
- wherein 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.
1 more element
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;
- and
- a 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.
