Claim:
1. A method of treating a diseased section of a blood vessel, comprising: implanting a bioabsorbable polymeric stent comprising a scaffolding composed of a pattern of struts at a diseased section of a blood vessel to form a stented segment comprising the stent and a vessel wall surrounding a lumen at the diseased section, wherein implanting comprises deploying the stent from a crimped diameter to a diameter of 3 mm, wherein a reference vessel diameter is 3 mm and a diameter stenosis of the diseased section of the blood vessel pre-implantation is greater than 50%, wherein the vessel wall comprises a plaque region including a necrotic core component and a fibrous component, wherein at pre-implantation and immediately following implantation of the stent the necrotic core component is in contact with the lumen, and wherein as the stent degrades the fibrous component covers the necrotic core component so that the necrotic core component is no longer in contact with the lumen.
