Process to Produce High-strength and Corrosion Resistant Alloy for Patient-Specific Bioresorbable Bone Fixation Implants and Hardware

详细技术说明

Project ID: D2016-43 IP Status: Provisional Patent Application # 62/270,227 Invention Description: Novel metallic alloy composition combined with a post-shaping heat-treatment process produces bioresorbable bone fixation hardware and implants. The technology produces stronger and less biocorrosive patient-specific devices than the base material. The methodology is applicable to various manufacturing processes such as 3-D printing and powder metallurgy. Applications: Bone fixation hardware and implant devices. Novelty: Newly-optimized alloy combined with heat treatment process. In addition to its role in improving the alloy's mechanical properties, the heat-treatment process also significantly enhances its biocorrosion properties, represented by a slower degradation rate of the alloy compared to a non-treated as-cast object in in-vitro tests. Value Proposition:•       Improves mechanical properties of metallic alloys.•       Stronger and less biocorrosive than currently available devices.•       Produced parts exhibit biocompatible corrosion byproducts that are known to encourage bone growth. •       Heat-treated alloy parts can be further coated with various types of biocompatible ceramic coatings for slower and more tailored biocorrosion rates.
