Abstract
Transluminal stents are disclosed herein. In some embodiments stents within the scope of this disclosure may comprise a first flared end and second flared end. In some embodiments, a profile of each of the first flared end and the second flared end may circumscribe a portion of separate elliptical arcs. In some embodiments, the stents are formed from braided or woven wires having a constant pitch along a middle region and continuously varying pitches along the first flared end and the second flared end. Methods of manufacturing stents are disclosed herein. Methods of using stents are also disclosed herein.
Claims20
A stent comprising:
- a hollow cylindrical body having an interior dimension and an exterior dimension and comprising a middle region that extends to a first flared end and also extends to an opposing second flared end,
- the first flared end comprising a first inner shoulder, a first crest, a first outer taper, and a first opening, wherein the first inner shoulder extends from one end of the middle region to the first crest, wherein a diameter of the first crest is greater than a diameter of the middle region, wherein the first outer taper extends from the first crest to the first opening, wherein the first opening provides a first boundary between the interior dimension and the exterior dimension,
- the second flared end comprising a second inner shoulder, a second crest, a second outer taper, and a second opening, wherein the second inner shoulder extends from one end of the middle region to the second crest, wherein a diameter of the second crest is greater than a diameter of the middle region, wherein the second outer taper extends from the second crest to the second opening, wherein the second opening provides a second boundary between the interior dimension and the exterior dimension,
- the hollow cylindrical body comprising braided or woven wires having a constant pitch along a length of the middle region, the braided or woven wires having a uniformly varying pitch along the first inner shoulder, the braided or woven wires having a constant pitch at the first crest, the braided or woven wires having a uniformly varying pitch along the first outer taper, the braided or woven wires having a uniformly varying pitch along the second inner shoulder, the braided or woven wires having a constant pitch at the second crest, and the braided or woven wires having a uniformly varying pitch along the second outer taper, wherein the uniformly varying pitch along the first and second inner shoulders is continuously decreasing from the middle region to the first and second crests, respectively.

A stent comprising:
- a hollow cylindrical body having an interior dimension and an exterior dimension and comprising a middle region that extends to a first flared end and also extends to an opposing second flared end,
- the first flared end comprising a first inner shoulder, a first crest, a first outer taper, and a first opening, wherein the first inner shoulder extends from one end of the middle region to the first crest, wherein a diameter of the first crest is greater than a diameter of the middle region, wherein the first outer taper extends from the first crest to the first opening, wherein the first opening provides a first boundary between the interior dimension and the exterior dimension,
- the second flared end comprising a second inner shoulder, a second crest, a second outer taper, and a second opening, wherein the second inner shoulder extends from one end of the middle region to the second crest, wherein a diameter of the second crest is greater than a diameter of the middle region, wherein the second outer taper extends from the second crest to the second opening, wherein the second opening provides a second boundary between the interior dimension and the exterior dimension,
- the hollow cylindrical body comprising braided or woven wires having a constant pitch along a length of the middle region, the braided or woven wires having a uniformly varying pitch along the first inner shoulder, the braided or woven wires having a constant pitch at the first crest, the braided or woven wires having a uniformly varying pitch along the first outer taper, the braided or woven wires having a uniformly varying pitch along the second inner shoulder, the braided or woven wires having a constant pitch at the second crest, and the braided or woven wires having a uniformly varying pitch along the second outer taper, wherein the uniformly varying pitch along the first outer taper is configured to allow the braided or woven wires at the first opening to expand equal to the diameter of the first crest and wherein the uniformly varying pitch along the second outer taper is configured to allow the braided or woven wires at the second opening to expand equal to the diameter of the second crest.
