| Abstract Scope |
Increased incidence of occlusive vascular diseases associated with aneurysms and coronary artery diseases demand the usage of small devices such as aneurysm clips and stents. From the materials perspective, it is of interest to develop new magnetic resistance imaging (MRI)-compatible alloys based on the elements with lower magnetic susceptibility, and to simultaneously meet the requirements of mechanical properties, corrosion resistance and biocompatibility.
In this contribution, we report the formation of novel biocompatible Ti-Zr-Nb-Hf-Si multi-principal element alloys with excellent corrosion stability in simulated body fluids and ultralow magnetic susceptibility, less than one-third of commercial biomedical Ti-materials. In addition, they exhibit higher X-ray linear attenuation coefficients relevant for interventional X-ray-based medical imaging. This two-fold advantage (lower magnetic susceptibility and higher radiopacity) allows the materials to be more precisely visualized via biomedical imaging methods, which is important for miniaturised implants.
