There is a need for a controllable, degradable, and adjustable stent to provide precise treatment in clinical practice. This study introduces a high\u2010performance biodegradable stent based on a uni\u2010material and uni\u2010process strategy to systematically address the demands of multiple biliary diseases. Taking high modulus and high orientation poly\u2010L\u2010lactic Acid (PLLA) monofilament as the basis of the research, the degradation behavior of Uni\u2010directional Stent is univariantly adjusted and precisely regulated by electron beam sterilization (EBS) technology. In vitro experiments showed that PLLA stents subjected to different doses of EBS can be tailored to meet the specific degradation cycles requirement for various biliary diseases by regulating molecular weight. Furthermore, a controlled relationship between the degradation behaviors of the materials in in vitro bile and Phosphate\u2010buffered saline (PBS) environments is also established, aiming to providing essential data and a theoretical foundation for streamlining future experiments.<\/jats:p>","DOI":"10.1002\/adhm.202503447","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T05:42:10Z","timestamp":1761716530000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Uni\u2010Directional Biodegradable Stent for Systematic Modulation in Biliary Diseases"],"prefix":"10.1002","volume":"15","author":[{"given":"Gutian","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhan","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xue","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuting","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinbo","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gensheng","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electronic Engineering Nanjing Forestry University  Nanjing Jiangsu 210037 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Lv","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Wu","sequence":"additional","affiliation":[{"name":"Hepatobiliary Center The First Affiliated Hospital with Nanjing Medical University Key Laboratory of Liver Transplantation Chinese Academy of Medical Sciences NHC Key Laboratory of Hepatobiliary cancers  Nanjing Jiangsu Province 212028 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aihua","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Hepatobiliary Center Jiangsu province (Suqian) Hospital Suqian Jiangsu 223800 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9906-4546","authenticated-orcid":false,"given":"Zhonghua","family":"Ni","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment Southeast University  Nanjing Jiangsu 211189 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,28]]},"reference":[{"key":"e_1_2_9_1_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12876-025-03842-x"},{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/liv.70103"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12029-024-01101-y"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/adhm.202501660"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmed.2024.1334154"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bioactmat.2022.01.017"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bioactmat.2024.03.018"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmps.2022.104983"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00289-025-05720-8"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1308\/003588414X13946184901326"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1089\/lap.2015.0068"},{"key":"e_1_2_9_12_1","first-page":"58","volume":"4","author":"Mullan D.","year":"2015","journal-title":"Gastro.
