Abstract
Stents generally can include a tubular structure having circumferentially positioned undulating wires that extend over a majority of a length of the stent such that the undulations oscillate circumferentially to define a circumference of the stent. The undulations can wrap over and under adjacent undulations to form an interwoven structure. Additionally, or alternatively, adjacent wires can be joined. Wires forming the stent can be cut from elastic tubing such that each wire has a three-dimensional shape.
Claims8
A stent comprising:
- a stent length measured from a first open end to a second open end;
- two or more wires each comprising a three-dimensional oscillating portion, the oscillating portion comprising:
- an oscillating portion length measured parallel to a z-axis;
- a curvature extending circumferentially through an arc of less than 360° about the z-axis, extending the length of the oscillating portion, and maintaining a substantially constant radius from the z-axis over the oscillating portion length;
- and
- a waveform oscillating circumferentially, confined within the arc of the curvature, and extending over the oscillating portion length;
- a first end structure positioned adjacent the first open end, extending between the first open end and the oscillating portion of each of the two or more wires;
- a second end structure positioned adjacent the second open end, extending between the second open end and the oscillating portion of each of the two or more, wires;
- wherein the oscillating portion length extends a majority of the stent, length;
- wherein the oscillating portion of each of the two or more wires is movable independent of the oscillating portion of every other of the two or more, wires;
- wherein the stent is movable from a collapsed configuration that is stretched lengthwise and has a smaller diameter to an expanded configuration that is compressed lengthwise and has a larger diameter;
- wherein the first end structure and the second end structure each comprises an atraumatic shape, the atraumatic shape of the first end structure being different from the atraumatic shape of the second end structure;
- and
- wherein the waveform of each of the two or more wires comprises undulations, the undulations of each wire recessing circumferentially within undulations of at least one of a circumferentially adjacent wire such that the circumferential positioning of the undulating wires defines a circumference of the stent.
