Biliary stents for active materials and surface modification: Recent advances and future perspectives
Demand for biliary stents has expanded with the increasing incidence of biliary disease. The implantation of plastic or self-expandable metal stents can be an effective treatment for biliary strictures. However, these stents are nondegradable and prone to restenosis. Surgical removal or replacement of the nondegradable stents is necessary in cases of disease resolution or restenosis. To overcome these shortcomings, improvements were made to the materials and surfaces used for the stents. First, this paper reviews the advantages and limitations of nondegradable stents. Second, emphasis is placed on biodegradable polymer and biodegradable metal stents, along with functional coatings. This also encompasses tissue engineering & 3D-printed stents were highlighted. Finally, the future perspectives of biliary stents, including pro-epithelialization coatings, multifunctional coated stents, biodegradable shape memory stents, and 4D bioprinting, were discussed.

期刊介绍:
Bioactive Materials is a peer-reviewed research publication that focuses on advancements in bioactive materials. The journal accepts research papers, reviews, and rapid communications in the field of next-generation biomaterials that interact with cells, tissues, and organs in various living organisms.
The primary goal of Bioactive Materials is to promote the science and engineering of biomaterials that exhibit adaptiveness to the biological environment. These materials are specifically designed to stimulate or direct appropriate cell and tissue responses or regulate interactions with microorganisms.
The journal covers a wide range of bioactive materials, including those that are engineered or designed in terms of their physical form (e.g. particulate, fiber), topology (e.g. porosity, surface roughness), or dimensions (ranging from macro to nano-scales). Contributions are sought from the following categories of bioactive materials:
Bioactive metals and alloys
Bioactive inorganics: ceramics, glasses, and carbon-based materials
Bioactive polymers and gels
Bioactive materials derived from natural sources
Bioactive composites
These materials find applications in human and veterinary medicine, such as implants, tissue engineering scaffolds, cell/drug/gene carriers, as well as imaging and sensing devices.
