Design and development and requirements of 7.1

I'm sorry, but I do not understand your first question - could you please elaborate?

Considering requirement 7.1 Planning of product realization, you need to plan and to develop the processes that you need to realize products. It means that you need to make procedures, forms and any other kind of document that will prove that your product is produced in a certain way. Also, you need to develop a risk management process for product realization. It means that you need to analyze your manufacturing process from the point of view of product safety for the patient. So, what can happen during production, which can cause the product to come out unsafe. For risk guidance, please look for ISO 14971:2012. 

You also need to plan how you're going to realize your product, what raw materials you need, what equipment, what kind of premises and other infrastructure. You need to formulate what are quality objectives for your product, clarify specific product realization requirements, generate product realization planning outputs.
