A thorough understanding of the adhesive materials’ interactions with the device and the user is crucial in the final stage of the product development process, ensuring the design specification meets all medical and regulatory requirements.

This stage solidifies the design refinements, where all aspects of the device, including its physical dimensions, materials, and functional features, are detailed in documentation. Finalizing the design specification requires a thorough review of how the adhesive materials interact with the device and the user, ensuring that the specifications meet all medical and regulatory requirements.

This can be done by collecting and analyzing data obtained by previously conducted internal wear and prototype studies. The complete specifications and final drawings serve as the definitive guide for manufacturing the product.
