Lubricious Hydrophilic Coatings
What performance parameters are crucial to launching your device in the market?
High lubricity is very important because it provides reduced friction forces compared with an uncoated device surface. This enhanced surface performance increases the device’s ability to navigate through tortuous anatomical pathways, improves device control, reduces tissue damage and adds to patient comfort.
Durability is crucial to the coating surface. The ideal chemistry will provide the photochemical covalent bond to the substrate producing superior adhesion and wear resistance while minimizing particulate formation.
Low Particulate Generation
Chemistry alone will not deliver high performance hydrophilic medical coatings. Both chemistry and the method of how the coating is applied determine the successful properties of the coating. The combination of state-of-the-art chemistry and the rigorous method behind the application is what deliver low particulate properties.
For applications where biocompatibility is required, it is important to make sure the coating has been successfully tested by an independent testing facility for ISO10993 biocompatibility. Specific tests included Cytotoxicity, Irritation, Acute Systemic Toxicity, Hemocompatiblity, Allergenic Potential, and Pyrogenicity.
Work with the supplier early in the product development cycle to determine the hydrophilic coating chemistries that are compatible with the possible device substrate material. This ensures the highest degree of success in the finished product.
