Bifurcated stent with surface area gradient

摘要

A stent may comprise a plurality of interconnected strut members defining a plurality of serpentine bands and a plurality of connector struts. Adjacent serpentine bands may be connected by at least one connector strut. The stent may further comprise an outwardly deployable side branch structure. The total amount of surface area of structural strut members in a given unit area on the surface of the stent is higher in areas near the side branch structure than in areas spaced away from the side branch structure.
