Claim 0:
1. A stent, comprising:
a radially expandable scaffold having a first end, a second end and an outer surface;
at least a first fixation member affixed directly to the radially expandable scaffold, the first fixation member configured to move from a constrained configuration to an extended configuration; and
a biodegradable material disposed along the first fixation member at a first tissue engagement region;
wherein the biodegradable material is configured to degrade from a first configuration in which the biodegradable material holds the first fixation member in the constrained configuration and shields the first fixation member from a target tissue site after the outer surface of the radially expandable scaffold has radially expanded into engagement with the target tissue site to a second configuration in which the biodegradable material is degraded while the radially expandable scaffold and the first fixation member remain intact, wherein degradation of the biodegradable material results in the first fixation member moving to the extended configuration and engaging the target tissue site.
