Segmentation by types classifies catheters according to structural design and functional capability, each influencing procurement patterns and price points. Conventional single‑lumen catheters dominate the volume‑based segment, offering a cost‑effective solution for standard imaging and representing the bulk of unit shipments. Dual‑lumen catheters, comprising roughly 15 % of the market, enable simultaneous contrast injection and pressure monitoring, attracting high‑complexity cardiac labs willing to pay a premium for procedural efficiency. Rapid‑exchange catheters, with a 25 % share, reduce insertion time and are favored in high‑throughput environments, thereby contributing disproportionately to revenue despite lower unit counts. Steerable catheters, accounting for about 10 % of sales, provide enhanced navigational control for tortuous anatomies, supporting specialized interventional procedures and commanding higher margins. Finally, microcatheters, representing the remaining 10 %, are essential for super‑selective vessel access in neuro‑ and peripheral interventions, adding niche but high‑value demand to the overall market.
