Types segmentation refines the market taxonomy by classifying products into balloon dilatation systems, self‑expanding metal stents (SEMS), biodegradable stents, and cutting or laser‑assisted devices. Balloon dilatation systems, characterized by controlled radial force and reusable catheters, dominate the benign segment, representing the largest share of procedural volume and generating stable revenue streams. SEMS, constructed from nitinol or stainless steel, are the preferred choice for malignant strictures, delivering rapid palliation and commanding premium pricing. Biodegradable stents, made of polylactic acid polymers, bridge temporary and permanent solutions, gaining traction in both pathways but still holding a modest share of overall sales. Cutting and laser‑assisted devices, used for refractory strictures, occupy a niche position due to higher procedural complexity. Collectively, these type categories explain the differential contribution of each product class to the total market size and guide strategic investment decisions.
