Abstract
A bioabsorbable biomedical implant is disclosed. The implant includes a tubular scaffold comprising a plurality of interconnected polymer struts. The interconnected polymer struts defines a plurality of deformable cells. The polymer struts have an average thickness of no more than 120 μm. Methods for making the bioabsorbable biomedical implant, including the methods for making the polymer materials for the tubular scaffold, are also disclosed.

A method of making a bioabsorbable tubular scaffold, the method comprising
- forming a composition comprising a bioabsorbable polymer;
- extruding the composition to form a polymer tube, wherein at least 50% of the bioabsorbable polymer is axially aligned with an axis of the polymer tube;
- and
- removing a portion of the polymer tube to form a scaffold comprising interconnected struts.
