1. Introduction

The aim of this Device Specific Vigilance Guidance ( DSVG) is to harmonise vigilance reporting and provide guidance for manufacturers of Coronary Stents and associated delivery systems. It provides further clarification for vigilance reporting of Coronary Stents and associated delivery systems to the relevant Competent Authority and should be read in conjunction with the requirements of Regulation (EU) 2017/745 on medical devices (MDR) [1]. This DSVG does not replace or extend any of those requirements.

This document outlines the way to report incidents and serious incidents, defined in Article 2(64) and (65) MDR, in accordance with Articles 87 and 88 MDR, which occurred with Coronary Stents and associated delivery systems to the relevant Competent Authority.

2. What should be reported

It is the manufacturer’s responsibility to judge each event on its own merit and to ensure compliance with the statutory reporting requirements contained within the MDR [1].

• • Individual serious incident

In accordance with Article 87 MDR [1] manufacturers shall report serious incidents to the relevant Competent Authority. Serious incidents are defined in Article 2(65) MDR.

This includes circumstances where the manufacturer is uncertain whether the incident that occurred with a specific device is reportable or needs time to obtain clarification about the root cause of the incident, in accordance with Article 87(6) and (7) MDR.

The notification to the relevant Competent Authority should be reported within the timeframes referred to in Article 87(2) and (5) MDR.

For further information and clarification on what constitutes a serious incident and for details on how to apply the reporting timelines of the MDR, please refer to MDCG 2023-31 “Questions and Answers on vigilance terms and concepts as outlined in the Regulation (EU) 2017/745 on medical devices” [2].

• • Periodic Summary Reporting

A “Periodic Summary Report” (PSR) is an alternative reporting regime by which the manufacturer, in agreement with the respective national Competent Authority that is coordinating the periodic summary reporting (and in consultation with the Competent Authorities referred to in Article 92(8)(a) MDR), can report similar serious incidents with the same device or device type in a consolidated way.

This is possible when similar serious incidents involving the same specific device or device type occur and for which the root cause has been identified or a field safety

1 MDCG 2023-3 guidance is under revision to include IVDR aspects. Please refer to the updated version when available at the following link: https://health.ec.europa.eu/medical-devices-sector/new-regulations_en#guidance.

corrective action has been implemented or where the serious incidents are common and well documented, as defined in Article 87(9) MDR.

The format, content and frequency of periodic summary reports should be agreed with the Coordinating Competent Authority (in consultation with the competent Authorities participating in the Periodic Summary Reporting) (Article 87(9) MDR).

Until EUDAMED becomes fully functional, Competent Authorities, economic operators and other relevant parties should follow MDCG 2021-1 Rev. 1 “Guidance on harmonised administrative practices and alternative technical solutions until EUDAMED is fully functional” [3] (as required under the MDR).

• • Trend Reporting

The requirements for trend reporting are outlined in Article 88 MDR [1].

In accordance with the MDR, the manufacturer should report to a Competent Authority any statistically significant increase in the frequency or severity of incidents that are not serious incidents or that are expected undesirable side-effects that could have a significant impact on the benefit-risk analysis and which have led or may lead to risks to the health or safety of patients, users or other persons that are unacceptable when weighed against the intended benefits. Trends should be identified by the manufacturer as they can be indicative of a change in the risk-benefit ratio.

For further information and clarification on what constitute incidents and undesirable side-effects please refer to MDCG 2023-3 “Questions and Answers on vigilance terms and concepts as outlined in the Regulation (EU) 2017/745 on medical devices” [2].
