A transluminal balloon for a medical device may include a longitudinal structural portion including at least a first structural layer, the first structural layer including a polyether block amide co-polymer including a polyether, and a polyamide other than nylon 12. A transluminal balloon may include a longitudinal structural portion including an inner structural layer including a first polyether block amide co-polymer, an intermediate structural layer including a polyamide or copolyamide, and an outer structural layer a second polyether block amide co-polymer different from the first polyether block amide co-polymer. The inner and outer structural layers have hoop ratios greater than the intermediate structural layer, and the inner structural layer has a hoop ratio that is greater than or less than the outer structural layer.
