摘要：
Methods of treating a diseased blood vessel exhibiting stenosis with a bioabsorable stent are disclosed. The implanted stent supports the section of the vessel at an increased diameter for a period of time to allow the vessel to heal. The stent loses radial strength sufficient to support the section of the vessel in less than 6 months after implantation, loses mechanical integrity, and then erodes away from the section. The biodegradable stent results in changes in properties of plaque with time as the stent degrades. The time-dependent properties include the luminal area of the plaque and plaque geometric morphology parameters.
