The global self-expanding stents market was valued at USD 3.35 billion in 2023 and is projected to grow at a CAGR of 4.1% from 2024 to 2033. This growth is fueled by rising demand for minimally invasive surgical solutions, advancements in biomaterials, and an aging global population increasingly prone to vascular diseases. Self-expanding stents, known for their unique ability to expand automatically in response to body temperature or vessel contact, have become a preferred option among surgeons due to improved patient outcomes and reduced recovery times.
Market Overview
Self-expanding stents are specialized medical devices used primarily in vascular surgeries to treat conditions like atherosclerosis and aneurysms. They’re made from materials such as nitinol (a nickel-titanium alloy) that enable them to change shape upon exposure to body heat or mechanical forces, allowing them to expand from a compact form during insertion to their functional size once in place.
Historically, the evolution of stents began with balloon-expandable metal stents, which required external force to open. Over time, the market shifted toward self-expanding stents due to their ability to adapt to vessel dynamics, provide continuous support, and minimize trauma to blood vessels during deployment. Today, these stents are widely used in treating peripheral artery disease, carotid artery disease, and various gastrointestinal and biliary conditions.
Their minimally invasive nature allows surgeons to insert them through small incisions, leading to shorter hospital stays and quicker patient recovery, making them increasingly favored in modern medical practice.
