International ClassesA61F 002/02A61L 029/00 AbstractMedical devices are formed from metal/polymer composites that have improved characteristics. The metal/polymer composites have a relatively thick metal coating with an average metal thickness of greater than about 3 microns. The composite has mechanical properties, such as mechanical strength, durability and resiliency, contributed by the metal coating. The metal/polymer composites can be formed by solution based or vapor based approaches.Other References
