Medical Devices Directive
The Medical Device Directive—Council Directive 93/42/EEC of 14 June 1993 concerning medical devices—is intended to harmonise the laws relating to medical devices within the European Union. The MD Directive is a 'New Approach' Directive and consequently in order for a manufacturer to legally place a medical device on the European market the requirements of the MD Directive have to be met.
