主权项

1. A flexible scaffold formed from expansion-crystallizable bioabsorbable polymer material comprising:
a first sinusoidal strut pattern comprising a series of repeated sinusoids defined by an apex section and a trough section; a nested hoop structure; and 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 shifted from about 0° to about 180° with respect to said apex section and said trough section of said first sinusoidal strut pattern; wherein said second sinusoidal strut pattern is connected to said first sinusoidal strut pattern at least two points, and when fully expanded, the first and second sinusoidal strut patterns maintain a sinusoidal shape and the nested hoop structure forms a hoop structure.
