摘要:
Implantable medical devices and methods of forming thereof made from polymers with end groups providing improved thermal stability are disclosed. Implantable medical devices made from such polymers including stabilizing agents are additionally disclosed.
摘要:
Medical devices, such as stents, fabricated at least in part from a polymer composite including a biodegradable elastomeric phase dispersed within a biodegradable polymeric matrix are disclosed. The composite is composed of a block copolymer including an elastomeric homopolymer block and a glassy polymer block.
摘要:
Medical devices and methods of fabricating such medical devices, such as stents, formed at least in part from a metal matrix composite including bioceramic particles dispersed within an erodible metal are disclosed.
摘要:
A balloon is inflated from a collapsed configuration, then deflated. A polymeric stent is then disposed over the deflated balloon and the stent crimped to the balloon.
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.
