Abstract: Stent device having stent wires interlocking with each other in various ways is disclosed. In primary interlocking structures, the stent wires include a loop formed in a first stent wire through which the second stent wire is threaded. Additional loops can be included in the primary interlocking structures, on one or both of the two stent wires. Primary interlocking structures are positioned at peaks and valleys in the respective first and second stent wires. Secondary interlocking structures do not contain loop features in the interlocking structure, but rather include first and second stent wires engaged with each other by passing first stent wire over the second stent wire forming a hanging arrangement with, e.g., the peak of one of the stent wires located in the valley of the other stent wire. Including one or more primary interlocking structures minimizes or prevents axial shortening and provides flexibility to the stent device.

Abstract: A stent formed by weaving wires includes: a plurality of straight-line crossing portions, which are formed by crossing at least two straight-line portions of the wires and are arranged adjacent to each other in a circumferential direction of the stent; and a plurality of interlocking portions configured by intersecting a peak-shaped bent portion, in which the wire is bent in a first direction side which is one side of a longitudinal axis direction of the stent and becomes convex, and a valley-shaped bent portion, in which the wire is bent in a second direction side which is the other side of the longitudinal axis direction and becomes convex, and arranged so as to be adjacent to each other in the circumferential direction of the stent, wherein the interlocking portions and the straight-line crossing portions are arranged alternately in the longitudinal axis direction.
