  • Bioabsorbable Stent And Treatment That Elicits Time-Varying Host-Material Response
    Publication number: 20100198330
    Abstract: 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.

  • Bioabsorbable Stent That Modulates Plaque Geometric Morphology And Chemical Composition
    Publication number: 20100198331
    Abstract: 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.
