Abstract: A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.
