1. A biosorbable and flexible scaffold circumferential about a longitudinal axis so as to form a tube, said tube having a proximal open end and a distal open end, and being crimpable and expandable, and having a patterned shape in expanded form comprising:
- a first multicomponent strut pattern helically coursing from said proximal open end to said distal open end of said tube;
a second multicomponent strut pattern helically coursing from said proximal open end to said distal open end of said tube;
wherein a component of said first multicomponent strut pattern opposes by from about 120°
to about 180°
a component of said second multicomponent strut pattern as each helically courses from said proximal open end to said distal open end of said tube.
