1. Technical Document
Documents related to quality of medical devices, such as functions, safety. etc
Includes information on raw materials, structure, purpose of use, instruction for use, principles of functions, precautions for use, test standards, etc.
2. Technical document classification
The technical document is consisting of application form and supportive documents and is divided into two different types: (1) General technical document review; and (2) clinical test review
2.1 General Technical Document Review
Devices substantially equivalent to previously approved products MFDS does not request clinical study reports
2.2 Review of Technical Documents Review for Safety and Efficacy Review (SER)
Review of Technical Documents Review for Safety and Efficacy Review (SER)
Scope: (Significant difference affecting safety and efficacy) New Developments, New performance, New structure, New purpose for use Clinical test reports are essential

- “Modified Device” is a medical device that is equivalent in the purpose of use, working mechanism, raw materials (Limited to medical supplies) with the already approved medical device, but not equivalent in performance, test specifications, instructions for use, etc
- “SE Device” is a medical device that is equivalent in the purpose of use, working mechanism, raw materials (Limited to medical supplies), performance, test specifications and instructions for use with the already approved medical device
- “Recognized SE Device” is a recognized medical device that is equivalent in the purpose of use, working mechanism, and so on defined by MFDS
