Composite stent

摘要

A bioremovable composite stent includes bioremovable polymer and bioremovable ceramic flakes generally coupled with adjacent layers of bioremovable polymer so as to make a resilient composite stent configured to move between a contracted configuration to an expanded configuration. In one embodiment, the composite stent may have a helical shape.
