Types segmentation dissects the market by graft architecture, material composition, fixation strategy, and delivery‑system profile, each shaping adoption patterns and price tiers. Modular endografts—assembled from separate proximal and distal components—represent the dominant design, offering flexibility for a range of neck lengths but incurring higher inventory complexity; they capture roughly 60 % of the device mix. Unibody systems, comprising a single‑piece graft, simplify implantation in narrow iliac arteries and account for about 25 % of sales, especially in regions with constrained vessel anatomy. Material sub‑categories include polyester and expanded polytetrafluoroethylene (ePTFE); polyester grafts dominate (70 %) due to established durability, while ePTFE, valued for lower profile, holds the remaining 30 %. Fixation mechanisms split between suprarenal and infrarenal hooks; suprarenal fixation, preferred for short necks, represents 55 %, whereas infrarenal accounts for 45 %. Finally, delivery systems are differentiated by profile: low‑profile (≤ 18 F) devices enable treatment of smaller access vessels and command a premium price, whereas standard‑profile systems remain cost‑effective for routine cases. Collectively, these type dimensions define the market taxonomy and drive differentiated revenue streams across the Abdominal Aortic Stent Graft and Delivery System market.
