Segmentation by type distinguishes four principal delivery‑system architectures: balloon‑mounted, self‑expanding, drug‑eluting (DES) integrated, and bare‑metal (BMS) platforms. Balloon‑mounted systems, which rely on a compliant balloon to expand a mounted stent, dominate the volume‑based share with an estimated 45 % of shipments, owing to their long‑standing clinical familiarity and lower unit cost. Self‑expanding systems, employing nitinol frames that automatically expand to vessel dimensions, represent roughly 20 % of the market; they are favored in lesions with high tortuosity or chronic total occlusions where controlled radial force is essential. Integrated DES delivery platforms combine a drug‑coated stent and a precision balloon, capturing about 30 % of revenue because of premium pricing linked to reduced restenosis risk. Finally, BMS platforms, now a niche, account for the remaining 5 % but still contribute to overall size through legacy contracts and cost‑sensitive health‑system procurement. The relative weight of each type shapes R&D focus, pricing strategies, and supply‑chain allocation across the Coronary Stent Delivery System market.
