Weakness

Affected products

What to do

Solution: Medtronic has developed mitigating patches for a subset of the affected implanted cardiac device models. These patches are installed during regular office visits. Medtronic has stated that patches for additional impacted models are being developed by Medtronic and will be deployed through future updates. Patches are currently available for the following affected models: * Protecta CRT-D and implantable cardioverter defibrillators (ICDs), all models * Amplia MRI CRT-D, all models (patch available in U.S. only) * Claria MRI CRT-D, all models (patch available in U.S. only) * Compia MRI CRT-D, all models (patch available in U.S. only) * Visia AF MRI ICD, all models * Visia AF ICD, all models * Brava CRT-D, all models                                             * Evera MRI ICD, all models * Evera ICD, all models * Mirro MRI ICD, all models * Primo MRI ICD, all models * Viva CRT-D, all models

Workaround: Medtronic has applied additional controls for monitoring and responding to improper use of the Conexus telemetry protocol by the affected implanted cardiac devices. Additional mitigations are being developed and will be deployed through future updates, assuming regulatory approval. Medtronic recommends that users take additional defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should: * Maintain good physical control over home monitors and programmers. * Use only home monitors, programmers, and implantable devices obtained directly from your healthcare provider or a Medtronic representative to ensure integrity of the system. * Do not connect unapproved devices to home monitors and programmers through USB ports or other physical connections. * Only use programmers to connect and interact with implanted devices in physically controlled hospital and clinical environments. * Only use home monitors in private environments such as a home, apartment, or otherwise physically controlled environment. * Report any concerning behavior regarding these products to your healthcare provider or a Medtronic representative. Medtronic has released additional patient focused information https://www.medtronic.com/security .
