Symposium Magnesium-based Biodegradable Implants
Presentation Title Absorbable Filament Technologies: Wire-drawing to Enable Next-generation Medical Devices

On-Site Speaker (Planned) Adam J. Griebel
Abstract Scope Nutrient metal technology may revolutionize the medical device industry by alleviating long-term side-effects associated with permanent metallic implants. Alloys of nutrient elements such as magnesium, iron, and zinc are being pursued as material solutions to enable absorbable devices. Efforts by the research community have focused on improving properties including corrosion rate, strength, and ductility of materials in each of the aforementioned material classes. Robust evaluation of candidate materials is a challenge that requires material in the correct form and device-accurate process-structure-function state. For medical devices, forms will include wires for orthopedic fixation (~1 mm diameter), surgical staples (~0.30 mm), stents (~150 Ám), and aneurysm occlusion (~20 Ám). Through a well-engineered wire-drawing process, substantial grain-refinement and strengthening are possible. This presentation discusses the primary advantages and challenges associated with the production of absorbable medical wire.
