Bioabsorbable Stent And Treatment That Elicits Time-Varying Host-Material Response

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. Upon complete absorption of the stent, the section moves and functions in a manner that is the same, more similar to, or substantially as a normal blood vessel. In particular, the section can have an increased diameter allowing increased blood flow and vasomotion is partially or substantially completely restored in the section.
