“…Furthermore, they recorded the friction coefficient during the controlled tissue damage testing and found that friction of catheters on aorta is a function of wear. The friction coefficient they measured was between 0.05 and 0.25, decreasing with consecutive sliding (representing different complexities of catheter intervention) of the catheter, which was attributed to increasing wear [72].…”

“…These issues encompass patient discomfort, soft tissue trauma, and a potential inflammation response arising from direct interaction with the soft tissue interface. Therefore, enhancing the lubrication properties of the implantable interventional devices is of paramount importance and also urgent. − Surface modification of medical devices is currently one of the hot research directions. In recent years, hydrophilic polymeric materials have been widely applied in the surface functionalization of medical devices, endowing the surfaces with better hydrophilicity and lubricity.…”

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.

“…Various biomedical catheters, e.g., urinary, tracheal, and central venous catheters, are extensively used in clinics. The materials used to manufacture the catheters are usually hydrophobic polymers including poly(tetrafluoroethylene), polyurethane, and poly(vinyl chloride) (PVC). , During the catheter insertion or dissection process, the lack of biological lubrication of these materials can lead to a variety of complications such as patient pain, soft tissue damage, and even inflammation when in direct contact with the soft tissue interface. − Consequently, it is particularly important to enhance the hydrophilicity and lubrication properties of the surface for the implanted biomedical catheters. It is widely accepted that the well-lubricated implant materials allow for smoother insertion and extraction, protect soft tissue from damage and inflammation, and increase patient compliance. − …”

The lubrication property of implanted biomedical devices is of great significance as it affects the clinical performance owing to direct contact with soft tissues. In the present study, a bioinspired copolymer with dual functions of both self-adhesion and lubrication was synthesized with N-(3-aminopropyl) methacrylamide hydrochloride, gallic acid, and 3-[dimethyl-[2-(2-methylprop-2-enoyloxy) ethyl] azaniumyl] propane-1-sulfonate by free radical polymerization and a carbodiimide coupling reaction. The copolymer was further modified on the surface of poly(vinyl chloride) (PVC) samples using a simple dip-coating method and was characterized by different evaluations including Fourier transform infrared spectroscopy, the water contact angle, X-ray photoelectron spectroscopy, optical interferometry, and atomic force microscopy. Additionally, the results of a series of tribological tests at the microscopic level demonstrated that the friction coefficient of the copolymer-coated PVC samples was significantly reduced compared to that of the bare PVC samples. Furthermore, the pull out test at the macroscopic level was performed using copolymer-coated PVC catheters on a poly(dimethylsiloxane)-based test rig, and the result showed that the copolymer-coated PVC catheters were endowed with a greatly decreased and much more stable pull out force compared with that of the bare PVC catheters. In conclusion, the bioinspired self-adhesive lubricated coating developed herein may be applied as a universal and versatile method to enhance the lubrication performance of implanted biomedical devices.
