Abstract
Bioresorbable medical devices, such as stents, scaffolds and other medical devices implantable in human and animal bodies, in which galvanic couples are formed. The devices include bioresorbable amalgamates, wires, laminates, layered structures or combinations thereof. Also, methods of manufacturing the devices, including laminating, folding, braiding, weaving, crocheting or cold spraying of materials with different galvanic potentials. Also, machining of amalgamated materials using electrical discharge machining..
