If you will not design any new products, it means that you are manufacturing already known products, that you can exclude requirement 7.3 Design and development. In our documentation toolkit, you do not need to use folder 09_Procedure_for_Design_and_Development.
If your medical device is not sterile, it means that requirement 7.5.5 Particular requirement for sterile medical devices and 7.5.7 Particular requirements for validation of processes for sterilization and sterile barrier systems.
