Within the Types taxonomy, catheters are classified by structural and functional characteristics into Single‑Lumen, Dual‑Lumen, Balloon‑Assisted and Integrated‑Sensor models. Single‑Lumen devices, the simplest architecture, dominate the low‑cost tier and support roughly 30 % of total unit sales, primarily in routine diagnostic procedures. Dual‑Lumen catheters, offering simultaneous fluid infusion and pressure monitoring, capture about 25 % of the market, favored in complex therapeutic interventions where precise control is essential. Balloon‑Assisted catheters, featuring an expandable segment for controlled dilation, command approximately 35 % of revenue, reflecting their critical role in advanced therapeutic protocols. Integrated‑Sensor catheters, embedding real‑time acoustic or pressure sensors, represent a niche yet high‑margin segment at 10 % of sales, driven by specialized research applications and premium clinical settings. This detailed type‑level breakdown illustrates each sub‑category’s quantitative contribution to the overall market and supports strategic decisions on product portfolio optimization.
