Evaluating Equivalence MEDDEV 2.7/1 Rev 4, June 2016

• Equivalence can only be based on a single device ; • Evaluators may wish to refer to several devices that are equivalent . In such a situation, equivalence of every single device to the device under evaluation should be fully investigated, demonstrated, and described in the clinical evaluation report. • All three characteristics (clinical, technical, biological) need to be fulfilled ; • Similar means that no clinically significant difference in the performance and safety of the device would be triggered by the differences between the device under evaluation and the device presumed to be equivalent; • the differences between the device under evaluation and the device presumed to be equivalent need to be identified, fully disclosed, and evaluated; explanations should be given why the differences are not expected to significantly affect the clinical performance and clinical safety of the device under evaluation;
