Abstract : The performance of distal access catheters is critical for their effectiveness in medical procedures. This study aimed to evaluate the mechanical properties and performance characteristics of a designed distal access catheter through a series of quality control (QC) tests. Six primary tests were conducted: friction, bond strength, stiffness, tensile strength, tip compression, and push report. The friction test evaluated the ease of insertion, while the bond strength test assessed the integrity of material connections. Stiffness and tensile tests were performed to measure flexibility and durability, while the tip compression and push tests examined the catheter’s ability to withstand operational forces. Results showed that the catheter met or exceeded all relevant performance standards, demonstrating high bond strength, optimal stiffness for navigation, and minimal friction during insertion. The catheter also exhibited excellent compressive resistance and push performance, confirming its suitability for clinical use. These findings suggest that the tested catheter design provides robust performance, ensuring enhanced reliability and safety for medical procedures requiring distal access. However, some limitations include uncertain long-term performance, potential procedural complexity, high costs, untested device compatibility, limited sample size, and risk of material fatigue. Future work will focus on long-term testing and further optimization of the catheter design. Statistical analysis confirmed repeatability and reproducibility, with minor variations within acceptable limits. The study establishes a link between the catheter’s mechanical properties and clinical efficacy, suggesting improved procedural efficiency and reduced vessel trauma. However, limitations such as long-term performance uncertainties and potential material fatigue remain. Future work will focus on long-term testing and further optimization of the catheter design. Although this study primarily evaluates the mechanical integrity of the catheter, the findings have significant clinical implications. A well-balanced combination of flexibility, pushability, and compressive resistance contributes to procedural success by enabling smoother navigation and reducing complications. Future research will aim to correlate these mechanical characteristics with real-world clinical outcomes, including procedural success rates, physician ease of use, and potential complication rates.
