Intra-aortic balloon pump (IABP): Maquet/Datascope CS100, CS100i and CS300 – potential for interruption or delay to therapy of critically ill patients

Manufactured by Maquet/Gettinge – a false blood detection alarm and/or fluid ingress could result in the failure of therapy to patients


Note: this MDA is for a different issue to the one described in MDA/2017/027 issued 24 August 2017.

  • Identify all affected devices – see the manufacturer’s Field Safety Notice (FSN) dated 17 July 2017. Products distributed from 24 March 2003 to 16 June 2017 inclusive are affected.

  • Use an alternative IABP or an alternative therapy for treatment if available.

  • If no alternative is available, undertake a risk assessment based on a clinical risk-benefit analysis. Affected devices which remain in use should be used in accordance with the manufacturer’s FSN.

  • Contact Maquet to confirm receipt of the FSN and to schedule both the software and hardware updates to prevent false alarms and installation of gaskets to prevent fluid ingress.
