DYNAMIC STENT

摘要

A stent (100) including a support frame (106) for supporting a vessel in a non-collapsed state is disclosed. The support frame (106) includes a degradable component (102) for at least initially supporting the vessel in the non-collapsed state when the stent (100) is first implanted in the vessel. The degradable component (102) is degradable after implantation such that support provided by the degradable component (102) decreases a selected amount after a predetermined time after implantation. The support frame (106) may further include a durable component (104) which is resistant to degradation such that support provided by the durable component (104) remains substantially constant after implantation.
