1. A 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 unexpanded form comprising:
- a first sinusoidal strut pattern comprising a series of repeated sinusoids defined by an apex section and a trough section, said repeated sinusoids coursing from said proximal open end to said distal open end of said tube;
a second sinusoidal strut pattern comprising a series of repeated sinusoids defined by an apex section and a trough section, said sinusoids of said second sinusoidal strut pattern being about 180°
out of phase to with respect to said apex and said troughs of said first sinusoidal strut pattern;
wherein said second sinusoidal strut pattern is connect to said first sinusoidal strut pattern at at least two points, and wherein said connection at said points is from an apex of a sinusoid of said first sinusoidal pattern to an apex of a sinusoid of said second sinusoidal pattern.
