ISO 13485 implementation

No, it is not mandatory for the company to go for the ISO 9001 as well. ISO 13485:2016 is a standard that is specific for Manufacturers of medical devices (Medical devices — Quality management systems — Requirements for regulatory purposes). Besides that, on the web pages of the European Commission are stated which standards are applicable for all types of medical devices:  https://ec.europa.eu/growth/single-market/european-standards/harmonised-standards/medical-devices On that list, which has around 300 standards, only ISO 13485:2015 is the standard for the quality management system.
