Within the type classification, Nitinol-based devices are grouped into stents, guidewires, orthodontic wires, filters and actuators, each delivering distinct functional benefits. Stents dominate the type segment, generating close to 45 % of market revenue due to their widespread use in coronary, peripheral and neurovascular interventions. Guidewires, valued for their flexibility and torque transmission, contribute approximately 20 %, serving interventional radiology and cardiology procedures. Orthodontic wires, leveraging shape‑memory for controlled tooth movement, hold about 15 % of the market, propelled by high patient acceptance of aesthetic treatments. Filters—particularly embolic protection and vena cava filters—account for roughly 12 %, as clinicians seek reliable debris capture solutions. Actuators, encompassing micro‑mechanical components for drug delivery and implant deployment, represent the remaining 8 %, reflecting niche but high‑value applications in robotic surgery and smart implants. This type‑level market taxonomy clarifies the revenue distribution across device categories.
