Abstract:
An apparatus for repair of an aneurysm in bifurcated blood vessels comprising:a main stent with a first, proximal portion and a second, distal portion, said proximal portion constructed with large mesh cell size and said distal portion constructed with smaller mesh cell size than said proximal portion; first and second sectional stents with first, frustro-conically tapered, proximal portions and second cylindrical distal portions, said proximal portions constructed with large mesh size and with semi-circular, proximal ends of said proximal portions, said distal portions constructed with smaller mesh size than said proximal portions, wherein said sectional stents fit contiguously into said distal portion of said main stent thereby completely filling said main stent; means for inserting said main stent and said first and second sectional stents into a bifurcated blood vessel at or near the bifurcation in the vessel; and means for fitting said first and second sectional stents into said main stent within the bifurcated vessel wherein a portion of said main stent is proximate to an aneurysm in the vessel wall.
