By Types, the market divides into Covered Stents and Uncovered Stents. Covered stents, comprising 65% of the segment, feature polymer or fabric linings to seal off aneurysms or prevent thrombosis, making them ideal for iliac vein stenosis or post-thrombotic syndrome. Their higher cost and specialized indications limit growth compared to uncovered stents, which dominate 35% of the market. Uncovered stents, preferred for simpler venous obstructions, rely on metal scaffolding alone, offering cost-effectiveness and broader applicability. This segmentation reflects a trade-off between functional specificity and procedural accessibility. Covered stents drive innovation in coatings and biocompatibility, whereas uncovered stents benefit from economies of scale. The balance between these types directly impacts overall market expansion, with uncovered models maintaining a larger volume share despite covered stents commanding premium pricing.
