Bifurcated stent for insertion within a branching vessel having a side branch aperture

摘要

A stent comprising: a first tubular member having a longitudinal bore formed from a sheet having eight sides, the second side connected to the eighth side and the fourth side connected to the sixth side, the third side and the seventh side defining a branch aperture disposed between the first side and the fifth side. The stent may further comprise a second tubular member having a longitudinal bore disposed and secured within the branch aperture of the first tubular member, the longitudinal bore of the second tubular member in fluid communication with the longitudinal bore of the first tubular member. These stents are devices that are suitable for implanting within bodily conduits including the vascular system to reinforce collapsing, partially occluded, weakened, or abnormally dilated sections of the blood vessel, and also may be implanted in other areas, e.g., the urinary tract or the bile duct to reinforce such bodily conduits.
