Abstract

In embodiments there is described a cardiovascular tube-shaped lockable and expandable bioabsorbable scaffold having a low immunogenicity manufactured from a crystallizable bioabsorbable polymer composition or blend.

Claims

1. A bioabsorbable 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 expandable from an unexpanded form to an expanded form, and being crimpable, said scaffold having a patterned shape in expanded form comprising:

a) a plurality of first meandering strut patterns, each of said first meandering strut pattern being interconnected to one another to form an interconnected mesh pattern circumferential about said longitudinal axis, and

b) at least two second strut patterns nested within said interconnected mesh pattern, each of said second strut patterns comprising a hoop circumferential about said longitudinal axis, said hoop having an inner surface proximal to said longitudinal axis and an outer surface distal to said longitudinal axis, said hoop inner and outer surfaces about their circumferences being orthogonal to said longitudinal axis and within substantially the same plane; and

c) at least one closed locking device connected to the crimped scaffold positioned circumferentially at proximal, distal or any other location along the scaffolding.

2. The scaffold of claim 1 wherein the locking device is a snap-fit type.
