Abstract:
A bioabsorbable stent and method of forming the same including a stent scaffolding formed from polymer layers with different degradation rates is disclosed. The polymer layers include an abluminal layer, a luminal layer, and optionally one or more middle layers. A degradation rate of the layers increases from the luminal layer to the abluminal layer.
