What is the Technical Documentation ?
Manufacturers are expected to prepare, and either hold or provide timely access to, documents that shows how each medical device was developed, designed and manufactured. The compilation of these documents is called Technical Documentation. Technical Documentation typically controlled in the manufacturer’s quality management system (QMS), is often extensive and sections of it may be held in different locations. The documentation is updated to reflect any changes made during the lifecycle of the device.
The Technical Documentation is used for selected premarket and postmarket conformity assessment activities. This documentation subset is intended to be in a consistent, summarised or abridged form, with sufficient detail to allow the Regulatory Affairs to fulfil its obligations. In the main, the documents contained within this subset are derived from the Technical Documentation held by the manufacturer and allow the manufacturer to demonstrate that the medical device to which it applies conforms to the Essential Principles of Safety and Performance of Medical Devices.
Note: Technical Documentation is a term used mostly in Europe for the CE-IVD marking. In the U.S., the term used is Common Technical Document (eCTD) or Design Dossier.
