Clinical Evaluation Guidance Document
All medical devices require a clinical evaluation and a clinical investigation in order to prove that the product is safe to be used by the intended users and that it achieves what the manufacturer claims the device was designed for, i.e. the device’s intended use. This document was designed to provide guidance to manufacturers of medical devices to help them understand the requirements for clinical evaluation and investigation of their product(s) under the new EU Medical Device Regulation 2017/745.

1.0 Introduction<br />
<strong>Clinical</strong> evaluation is the systematic process of collecting and analysing clinical data of a<br />
medical device, the clinical information is collected from the post-market surveillance (PMS)<br />
and from the post-market clinical follow-up (PMCF). This process aims to provide patients<br />
and healthcare professionals with confidence about the device which they are going to use.<br />
The clinical evaluation ensures the safety and the effectiveness of the device and meanwhile<br />
ensures that the device is going to quickly be available on the market. Furthermore, this<br />
process aims to increase the availability of innovative companies by attracting investors,<br />
estimate costs and most importantly anticipate procedures. This document aims to give<br />
guidelines to any responsible body who is involved in the clinical evaluation. Furthermore,<br />
this document is going to illustrate the relationship between the clinical evaluation and<br />
other important processes and explain the impact on them. Appendix A illustrates the<br />
difference between the EU MDR and MDD regarding clinical evaluation.<br />
2.0 Relationship between the clinical evaluation and other processes<br />
The flowchart below illustrates the relationship between the design development phase and<br />
the post production phase. Through these two phases it is shown that the clinical evaluation<br />
is directly linked with the PMCF and hence with the PMS.<br />
