![]() This disease affects a wide patient population worldwide, with more than 200 million individuals afflicted. Percutaneous transluminal coronary angioplasty (PTCA) is an effective approach for treating symptomatic atherosclerotic peripheral artery disease. Peripheral artery disease (PAD) is a long-term arterial disease caused by atherosclerosis in the peripheral vessels, leading to complications in limbs such as pain, ulcers, gangrene, and reduced function. This method can assess the performance of balloons made from diverse materials navigating curved paths and can yield more precise and detailed data feedback compared to benchtop experiments. The numerical simulation method used in this study can be used for relevant research. However, when using the same friction coefficient, the difference in insertion forces between the two materials is minimal. The simulated insertion forces of nylon-12 align with the experimental results. Conclusion: nylon-12 exerts greater pressure on the vessel wall in curved pathways when compared to Pebax. In terms of insertion force, nylon-12 was higher than Pebax in specific areas. In the simulation, nylon-12 experienced a higher level of stress after folding, while Pebax had demonstrated a higher effective strain and surface energy density. Results: In the bench test, nylon-12 demonstrated the highest insertion force, peaking at 0.866 N, significantly outstripping the 0.156 N force exhibited by the Pebax balloon. The simulation built a model identical to the bench test’s groove and simulated the balloon’s folding process prior to insertion to better replicate the experimental conditions. Methods: Two materials, nylon-12 and Pebax, were examined for their insertion forces via a bench test and a numerical simulation. ![]() This project seeks to unveil the underlying patterns more effectively by utilizing a highly realistic balloon-folding simulation method to compare the trackability of balloons made from different materials. Objective: Thus far, numerical simulation studies comparing the impacts of different materials on the trackability of balloon catheters has been limited. Various factors, including the material used, influence the ability of different types of balloons to navigate through lesions during delivery. Background: A balloon dilatation catheter is a vital tool in percutaneous transluminal angioplasty.
