“…Ueng et al [39] fabricated vascular stents by braiding stainless-steel fibers combined with nitinol fibers (0.08 mm in diameter). Sun et al [40] applied the braiding technique for biodegradable stent fabrication by using poly(p-dioxanone) (PPDO) monofilaments and PCL/PPDO composite filaments, and mechanical testing results showed that the mechanical properties of the braided biodegradable stents were comparable to metallic stents including elastic recovery rate, deformation rate, and expansion behavior, as shown in Figure 1.…”

Percutaneous coronary intervention (PCI) with stent implantation is one of the most effective treatments for cardiovascular diseases (CVDs). However, there are still many complications after stent implantation. As a medical device with a complex structure and small size, the manufacture and post-processing technology greatly impact the mechanical and medical performances of stents. In this paper, the development history, material, manufacturing method, and post-processing technology of vascular stents are introduced. In particular, this paper focuses on the existing manufacturing technology and post-processing technology of vascular stents and the impact of these technologies on stent performance is described and discussed. Moreover, the future development of vascular stent manufacturing technology will be prospected and proposed.

Percutaneous Coronary Intervention (PCI) is currently the most conventional and effective method for clinically treating cardiovascular diseases such as atherosclerosis. Stent implantation, as one of the ways of PCI in the treatment of coronary artery diseases, has become a hot spot in scientific research with more and more patients suffering from cardiovascular diseases. However, vascular stent implanted into vessels of patients often causes complications such as In-Stent Restenosis (ISR). The vascular stent is one of the sophisticated medical devices, a reasonable structure of stent can effectively reduce the complications. In this paper, we introduce the evolution, performance evaluation standards, delivery and deployment, and manufacturing methods of vascular stents. Based on a large number of literature pieces, this paper focuses on designing structures of vascular stents in terms of “bridge (or link)” type, representative volume unit (RVE)/representative unit cell (RUC), and patient-specific stent. Finally, this paper gives an outlook on the future development of designing vascular stents.

In addition, it requires a fundamental understanding of the structure and function of the target tissue type.Tubular tissues, such as vascular, respiratory, or intestinal systems supply the body with important nutrients and transport blood, air, food, or fluids. A defect in these tissues can considerably affect the patient's quality of life, for example, the required surgical reconstruction of connecting pathways between two anatomical structures can significantly reduce the patient's mobility. Current treatment strategies for diseased tubular tissues include transplantations of donor organs, autologous tissues, or implantable medical devices to restore tissue function. [2] However, transplants of donor organs or autologous tissue are limited due to availability, donor site morbidity, and risk of disease transmission. [3] Compared to natural body parts, implants have not yet reached the functionality, quality, or longevity (often need replacement after years). [3] Moreover, they must remain in the body for years, and material-specific compatibility problems can cause chronic inflammatory responses, thus limiting their clinical use. Being able to develop tissues outside the body provides a longterm alternative to organ transplantation that could offset the increasing discrepancy between the required number of donor organs needed and availability due to a growing and aging population and the higher life expectancy. [1] Additionally, eliminating the need for time-intensive therapy, for example, immune suppressants, and improving the patient quality of life. [1] Tubular tissues have many unifying structural and biomechanical characteristics despite their different functions. They consist of a multi-layered muscular wall structure of multiple different cell types. The different cell types are embedded in a surrounding environment, the extracellular matrix (ECM). [1] The ECM serves for the spatial organization of the cells and consists of fibrous structures, for example, collagen or elastin, which are proteins that form fiber bundles. [2] Fibrous structures can be found throughout the human body, whether in the architecture and ECM of specific tissue structures, such as arteries, lymphatic vessels, cartilage, or in the fibrous nature of nerves, muscles, ligaments, tendons. [4] A major aim of TE is to mimic the ECM and develop a 3D scaffold that will be seeded with native cells for tissue formation. Current scaffold designs of tubular tissues include foams, gel mattresses, sponges, meshes, and nanofibrous structures. [5] The scaffold serves as a template In cell-free scaffold tissue engineering (TE), an essential prerequisite is the scaffold design to promote cellular activities and tissue formation. The success is greatly dependent upon the nature of the scaffold including the composition, topography, and mechanical performance. Recent TE approaches use textile technologies to create biomimetic and functional scaffolds similar to the extracellular matrix (ECM). The hierarchical architecture of fiber to yarn to fabric a...
