Abstract

An expandable bifurcated stent comprising a proximal end and a distal end in communication with one another. The proximal end comprises a primary passageway and the distal end comprises a pair of secondary passageways. The stent is expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force exerted on the stent. Each of the primary passageway and the secondary passageway being constructed of a tubular wall having a porous surface, a method for production of a bifurcated stent is also described. The method comprises the step of connecting a first stent section to a second stent section, the first stent section having an end thereof adapted for connection to an opening disposed along the length of a second stent section.

Claims (65)

1. An expandable bifurcated stent comprising a proximal end and a distal end in communication with one another, the proximal end comprising a primary passageway and the distal end comprising a pair of secondary passageways, the stent being expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force exerted on the stent, each of the primary passageway and the secondary passageway being constructed of a tubular wall having a porous surface.
2. The bifurcated stent defined in claim 1, wherein the primary and each secondary passageway is elongate and has a longitudinal axis which substantially bisects the pair of secondary passageways.
3. The bifurcated stent defined in claim 2, wherein the porous surface is defined by a plurality intersecting members.
4. The bifurcated stent defined in claim 3, wherein the intersecting members define a first repeating pattern.
5. The bifurcated stent defined m claim 4, wherein the first repeating pattern is a first repeating pattern comprised of a polygon having a pair of side walls substantially parallel to the longitudinal axis, a concave-shaped first wall having a first apex and a convex-shaped second wall having a second apex, the first wall and the second wall connecting the side walls, at least one of the first apex and the second apex being substantially flat.
6. The bifurcated stent defined in claim 5, wherein both the first apex and the second apex are substantially flat.
7. The bifurcated stent defined in claim 5, wherein the first apex and the second apex are of different length.
8. The bifurcated stent defined in claim 5, wherein the first apex and the second apex are of the same length.
9. The bifurcated stent defined in claim 5, wherein the first wall and the second wall are substantially equidistant from one another along an axis parallel to the longitudinal axis.
10. The bifurcated stent defined in claim 5, wherein one of the first apex and the second apex is substantially arcuate.
