Bewertung 2007/47/EG Änderungen Klin. Bewertung Annex II: 5.2. The manufacturer must authorize the notified body to carry out all necessary inspections and supply it with all relevant information, in particular [...] the data stipulated in the part of the quality system relating to design, such as the results of analyses, calculation test, the solutions adopted in accordance with Annex I section(2), preclinical and clinical evaluation, post-market clinical followup and results of the post-market clinical follow up, if applicable [...]

3 Klinische Daten Anhang X Die klinische Bewertung und ihre Dokumentation müssen aktiv anhand der aus der Überwachung nach dem Inverkehrbringen erhaltenen Daten auf dem neuesten Stand gehalten werden Wird eine klinische Überwachung PMCF Post Market Clinical Follow UP nach dem Inverkehrbringen [ ] nicht für erforderlich gehalten, muss dies ordnungsgemäß begründet und dokumentiert werden. MEDDEV Abteilung: 5 PMCF MEDDEV PMCF should always considered for devices where: In the case the assessment of a product is performed through the concept of equivalence ( literature route!) identification of possible emerging risks is critical the evaluation of long term safety and performance is critical (implants!)

4 Criteria to identify emerging risk: innovation severity of the disease sensitive target population risky anatomical site well known risks from literature or marketed devices obvious discrepancy between the pre-market follow up timescale and the expected life of the product PMCF MEDDEV All PMCF should be planned: form of extended follow-up of patients enrolled in the pre-market trials and/or a prospective study of a representative subset of patients after the device is placed on the market

5 This plan will need to take into account: Results of the clinical investigation including Adverse events identified Average life expectancy of the device The claims made by the manufacturer for the device Performances for which equivalence is claimed New information becoming available PMCF MEDDEV No PMCF: Products for which the medium/long term clinical performance and safety is already known from previous use of the device or from fully transferable experience with equivalent devices (Products quoted as "equivalent" devices where reference product is subjected to PMCF)

6 Conclusion PMCF Plan Follow up of a pre-market trial Post-market prospective trial (cave: national requirements!) The notified body should review the appropriateness of the plan and the procedures The follow-up should take into account the average life expectancy In the case the assessment of a product is performed through the concept of equivalence, PMCF should always be considered.
