Application‑based Vascular Interventional Navigation Robot segmentation isolates demand into four clinical domains: Coronary artery disease (CAD), Peripheral arterial disease (PAD), Neurovascular disorders, and Other vascular interventions (e.g., renal, mesenteric). CAD procedures command the largest share, estimated at 45% of market revenue, because coronary interventions generate the highest procedural volume and exhibit strong incentives for precision and radiation reduction. PAD follows with a 30% contribution, reflecting expanding use of endovascular therapy for lower‑extremity occlusions and the suitability of robotic platforms for long, straight vessel pathways. Neurovascular applications, though technically demanding, account for 15% of sales, driven by growing adoption in stroke thrombectomy and aneurysm coiling where sub‑millimeter accuracy is critical. The remaining 10% covers other interventions, where robotic assistance is emerging but still limited by anatomical complexity and lower case numbers. This application taxonomy clarifies how clinical need shapes revenue distribution within the overall market.
