“…BVS microtubes made of three alloys were fabricated with an outer diameter of 3 mm and thickness of 180 μm (Figures 2(a) occurred and led to the increase of UTS, elongation, and hardness to 410 MPa, 18.5% and 114 HV from 230 MPa, and 5.1% and 80 HV, respectively. Thus, WE43 microtubes with high strength and ductility fabricated using the combined approach can be used as BVS [25].…”

Currently, biodegradable metals for implantation applications are widely investigated to replace biodegradable polymeric implantations, which may cause inflammatory or adverse local tissue reactions. Amongst these metals, magnesium (Mg) and zinc (Zn) alloys with good biocompatibility, mechanical properties, and corrosion resistance are being widely investigated. In this review, the criteria for biodegradable vascular stents, and the advantages and limitations of biodegradable Mg and Zn vascular stents, are summarized and evaluated. By summarizing and discussing recent research on Mg- and Zn-based alloys used as biodegradable vascular stents, this review considered many alloys that can potentially serve as biodegradable vascular stents and suggests future research directions for the development of Mg- and Zn-based alloys as biodegradable metal stents.

Severe Plastic Deformation (SPD) processes have been extensively investigated in the last 30 years to facilitate the production processes of nanostructured (NS) or ultrafine-grained (UFG) materials with unique properties. However, the majority of the efforts were limited on the laboratory-scale investigations not to be able to overcome the demands for industrial scale applications. Researchers have tried to introduce effective industrial methods for processing large and long UFG/NG materials. In this review, all industrial processes especially continuous SPD methods which are more suitable for mass production are categorized and explained. Furthermore, the factors influencing the process efficiency were presented to give a vision to the researchers who want to step in this scientific field. Finally, the industrial processes were compared regarding final microstructure and properties.

“…According to the World Health Organization (WHO), cardiovascular diseases are among the most prevalent and leading causes of death worldwide [ 1 ]. The WHO estimates that about 17 million deaths annually are related to cardiovascular diseases, and this number will increase up to around 23.6 million by 2030 [ 2 ]. Usually, cardiovascular-related illness is associated with disorders in the heart, blood vessels, or both.…”

3D Printing of Polymeric Bioresorbable Stents: A Strategy to Improve Both Cellular Compatibility and Mechanical Properties

2022

One of the leading causes of death is cardiovascular disease, and the most common cardiovascular disease is coronary artery disease. Percutaneous coronary intervention and vascular stents have emerged as a solution to treat coronary artery disease. Nowadays, several types of vascular stents share the same purpose: to reduce the percentage of restenosis, thrombosis, and neointimal hyperplasia and supply mechanical support to the blood vessels. Despite the numerous efforts to create an ideal stent, there is no coronary stent that simultaneously presents the appropriate cellular compatibility and mechanical properties to avoid stent collapse and failure. One of the emerging approaches to solve these problems is improving the mechanical performance of polymeric bioresorbable stents produced through additive manufacturing. Although there have been numerous studies in this field, normalized control parameters for 3D-printed polymeric vascular stents fabrication are absent. The present paper aims to present an overview of the current types of stents and the main polymeric materials used to fabricate the bioresorbable vascular stents. Furthermore, a detailed description of the printing parameters’ influence on the mechanical performance and degradation profile of polymeric bioresorbable stents is presented.
