Drug-device combination product, which comprises at least a drug and a medical device, has been proved to effectively reduce the risk of complications accompanied with conventional medical devices implantation, and has a great clinical success especially in implantable therapeutics. Herein, we firstly elaborated the definitions and requirements of drug-device combination product in different countries, then summarized the market application and research development of typical drug-device combination products. Technical problems and the trend of future development had also been analyzed.
