Biliary Stents Industry Outlook: Metal Stents Support Advanced Biliary Interventions

The global biliary stents market size was valued at USD 497.68 million in 2025 and is projected to grow from USD 525.55 million in 2026 to USD 812.69 million by 2034, registering a CAGR of 5.6% during the forecast period 2026–2034. Biliary stents are medical devices used to maintain bile flow by relieving obstructions caused by gallstones, biliary strictures, pancreatic cancer, and other biliary disorders. Demand is supported by the increasing use of endoscopic procedures, the need for minimally invasive interventions, and advancements in stent materials and designs. North America dominated the market with a 38.4% share in 2025, while Asia-Pacific is expected to experience faster growth as healthcare access and procedural capabilities expand.

The prevalence of biliary disorders, gallstones, pancreatic cancer, and bile duct cancer supports demand for biliary stents. These devices help restore bile drainage and relieve complications associated with obstructed ducts. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous interventions provide established routes for stent placement, supporting their use in clinical practice. The growing emphasis on minimally invasive treatment also encourages healthcare providers to use techniques that can reduce recovery time and the burden associated with more invasive procedures. Together, these factors support market growth across hospitals and specialized treatment facilities.

Biliary stents can experience occlusion, migration, tissue overgrowth, and recurrent strictures, potentially requiring replacement or additional interventions. Plastic stents are particularly susceptible to blockage from sludge and biofilm formation, while metal stents may present removal challenges in certain clinical situations. These complications can increase healthcare costs and affect patient outcomes. Manufacturers must continue improving stent durability, patency, and ease of placement and removal to address clinical limitations and strengthen confidence in existing technologies.

Improvements in stent materials, coatings, and deployment systems create opportunities for medical device manufacturers. Drug-eluting designs, anti-migration features, and bioresorbable technologies are being explored to address complications such as tissue ingrowth and stent occlusion. These innovations could improve device performance in selected clinical applications and help companies differentiate their portfolios. Investment in research and development, alongside collaboration with healthcare providers, can support the development of devices tailored to different biliary conditions and treatment requirements.

Metal stents are widely used because of their radial strength, conformability, and ability to maintain duct patency. Their self-expanding designs support placement through endoscopic or percutaneous techniques, making them suitable for various biliary obstructions. Plastic stents remain relevant because of their lower cost and suitability for temporary drainage. This combination of durability-focused metal products and cost-effective plastic options allows clinicians to select devices according to patient needs and treatment objectives.

The continued use of endoscopic biliary interventions is shaping product development and clinical demand. Healthcare providers require stents that can be accurately deployed and maintain drainage while minimizing complications. Manufacturers are therefore focusing on improved flexibility, placement control, and designs that address migration and blockage. These priorities influence the competitive landscape and create opportunities for differentiated medical devices.

The market includes metal, polymer, and plastic biliary stents. Metal stents held the dominant position, supported by their radial force, conformability, and longer patency in many applications. Plastic stents offer a lower-cost option for temporary drainage and selected benign conditions. Polymer-based products provide another material category for device development, with product selection depending on clinical requirements, duration of treatment, and removal considerations.

Applications include biliopancreatic leakages, pancreatic cancer, benign biliary strictures, and gallstones. Gallstones represented the leading application segment, with stents used in selected cases to restore drainage when immediate or definitive stone removal is not feasible. Biliary stents are also used to manage leaks by redirecting bile away from the affected area. In pancreatic cancer and other malignant obstructions, stenting can help relieve blockage and improve bile flow.

Hospitals and ambulatory surgical centers constitute the principal end-user segments. Hospitals accounted for the largest share, supported by their advanced imaging facilities, specialized clinical teams, endoscopy departments, and capacity to manage complex biliary interventions. Ambulatory surgical centers provide an additional setting for suitable procedures, depending on patient needs and local healthcare infrastructure.

North America held the leading 38.4% market share in 2025 and is projected to grow at a CAGR of 5.3% during 2026–2034. Demand is supported by established healthcare infrastructure, access to endoscopic procedures, and the availability of advanced medical devices. Hospitals and specialist centers remain important customers as healthcare providers manage biliary obstructions associated with malignant and benign conditions.

Asia-Pacific is projected to register a CAGR of 5.9% during 2026–2034, making it the fastest-growing region. Expanding healthcare access, growing patient populations, and the development of medical facilities in countries such as India and China support regional opportunities. Wider access to specialized procedures and increasing availability of advanced devices could further strengthen demand.

Europe benefits from established healthcare systems, specialist gastroenterology services, and demand for minimally invasive interventions. Device quality, clinical performance, and reliable supply remain important considerations for hospitals and healthcare providers.

These regions offer opportunities as healthcare infrastructure and access to specialized interventions develop. Market expansion depends on device affordability, availability of trained clinicians, hospital investment, and access to diagnostic and endoscopic equipment.

The biliary stents market includes established medical device manufacturers serving hospitals and specialist healthcare facilities. Key companies include Boston Scientific, Cook Group, ENDO-FLEX GmbH, Olympus Corporation, B. Braun Melsungen, CONMED Corporation, M.I. Tech, Becton, Dickinson and Company, Medtronic plc, Cardinal Health, and Merit Medical Systems.

Competition is influenced by product performance, placement precision, durability, clinical suitability, pricing, and distribution reach. Manufacturers are focusing on design improvements and technologies that address migration, occlusion, and tissue-related complications. Continued innovation and strong relationships with healthcare providers will remain important to strengthening market share and supporting long-term market expansion.
