“…In this study, simplified mechanical models were constructed, without the fluid-structure interaction (FSI), and the lubrication effect of blood was neglected. In fact, in the catheter-stent-vessel system, the blood flow can cause the shear-thinning effect, which can significantly affect the wall shear stress (Liu et al, 2018 ), and the blood can also change the friction on the contact surface (Wagner et al, 2021 ). Moreover, in the FE model, the blood vessel was shaped as a soft tube with different curvatures under identical inner diameter.…”

At present, percutaneous coronary intervention (PCI) is the most effective treatment of coronary artery stenosis. However, in case post-dilation of the stent is needed, the tip of the commonly used post-dilation balloon catheter cannot always pass through the stent smoothly, especially when it is situated in the curved part of the vessel. To improve the performance of traditional post-dilation balloon catheter, a preliminary design of a novel catheter with a spherical-tip is proposed. Since the performance of this spherical-tip catheter is still unclear, in this study, finite element analysis (FEA) and experimental validation of blood vessel with different curvature radii were performed to test and evaluate the performance of the spherical-tip catheter design. The comparative results between the two types of catheters demonstrate that in the simulated post-dilation process, the spherical-tip catheter is easier to pass through the stent placed in the curved vessel without the deformation of the stent strut, and can theoretically reduce the operation time and improve the safety of the operation. Furthermore, the strong consistency between simulation and experiment indicates that the finite element (FE) model can be a helpful tool for future optimization and evaluation of novel catheters, so as to save time and budget in product development and reduce/replace animal studies.

“…Despite the implementation of asepsis treatment and anticoagulant administration to mitigate infection and thrombosis, PICC-related infections and thrombosis remain prevalent and pose significant risks to patients undergoing PICC therapy [ 6 ]. Furthermore, there is a need for reduced surface friction during tube insertion in PICC therapy to prevent blood vessel injury, as high surface friction between the tube and blood vessels causes unexpected movements during the cardiac catheterization process, leading to blood vessel injury, hemorrhage, and arterial spasms [ 7 , 8 ]. To address these challenges, it is necessary to minimize the incidence of CABSI, thrombosis, and surface friction for the safe utilization of catheter devices.…”

Surface modification of lubricating coatings on biomedical devices is a pivotal strategy to improve the overall performance and clinical efficacy, significantly reducing friction between devices and human tissues and mitigating tissue damage during intervention and long-term implantation. Recently, various hydrophilic polymeric materials have been used for achieving surface functionalization, endowing the biomedical device with excellent superlubrication performance. N-Vinylpyrrolidone (NVP) and 2-methacryloyloxyethyl phosphorylcholine (MPC) are two typical representatives of nonionic and zwitterionic materials. However, there is still a research gap in a comparative study of the lubrication mechanisms and properties between them. In this study, a bioinspired and dopamine-assisted codeposition technique was used to fabricate biomimetic hydrophilic coatings, including P(DMA-NVP) and P(DMA-MPC), on polyurethane. To achieve a thorough comparative analysis of the self-adhesive coating performance, 3 M ratios of the copolymers were synthesized and comprehensive material evaluations were conducted. Additionally, surface morphology, hydrophilicity, and lubrication at both the microscale and macroscale were performed. It was found that both hydrophilic coatings exhibited good stability. The P(DMA-MPC) coating, due to the ability to attract and bind a large number of water molecules, demonstrated superior lubrication effects compared to the P(DMA-NVP) coating. The study provides an in-depth understanding of the lubrication behavior of the self-adhesive coatings to enhance the functionality and application in biomedical engineering.
