  Medtronic CareLink SmartSync Patient Connector, Model Number 24967 with the following software components: 1. Cobalt Crome application, Software Model Number D00U005; 2. Claria Amplia Compia application, Software Model Number D00U009; 3. Evera MRI application, Software Model Number D00U010; 3. Visia AF application, Software Model Number D00U011; 5. Viva Brava Evera application, Software Model Number D00U012;

  In prior SmartSync application versions, the Abort button stopped the test that was selected. During an induction test, there was a limited window of time for the user to abort a therapy, thereby limiting the user's ability to cancel a high voltage therapy delivery.

  Azure S DR MRI SureScan, Product number W3DR01

  Identified devices may experience sudden battery power failure without alarm, power supply power-on-resets, and interruption of therapy. Potential patient harms include insufficient pacing support leading to cardiac arrest, syncope, or hospitalization; or system revision (explant/replacement) leading to infection, hematoma, or temporary impairment.

  Merlin@home with the MerlinOnDemand capability Transmitter REF EX1150 Merlin@home with the MerlinOnDemand" (MoD) capability is a transmitter configured for multiple patient use. It can receive information from an implantable heart device in unpaired mode. With MoD capability, the transmitter will retrieve full follow-up data or retrieve data for display on the Merlin.net" Patient Care Network (PCN). The MoD capability enables clinicians to do the following: . support remote care patients in emergency rooms and heart failure clinics . triage patients for in clinic follow-ups . support patients in a clinical setting with Merlin.net PCN

  Due to heart transmitter not being able to upgrade to the current software version in the field after experiencing a power interruption during a prior over-the-wire software download.

  Patient Connector, Model Number 24967

  There is a rare communication sequence during the first device interrogation with a SmartSync Device Manager that may result in the temporary suspension of some device features (i.e., battery measurements, Capture Management", Atrial Lead Position Check", EffectivCRT" algorithms, and AdaptivCRT"). This rare interaction results in temporary suspension of automatic threshold testing and output adjustments, and suspension of auto-optimization of CRT therapy. The issue is unlikely to result in clinical impact to the patient, and features are restored upon next programmer device interrogation or presence of a magnet.
