2090 CareLink™ Programmer |
January 2019
Dear Risk Manager or Healthcare Professional:
This letter is to inform you ofthe availability of a software update for Medtronic 2090 CareLink and 29901 Encore programmers. The update is specific to the programmer software that supports the Micra Transcatheter Pacing System (TPS) device and is released under the application software ID: Model SW022 version 8.1. This software update corrects an error in how the programmer calculates and displays the remaining longevity value during a period of time (up to 2 years) prior to the device reaching its Recommended Replacement Time (RRT).
The software display error does not reflect any issues with the Micra TPS device battery, its ability to deliver therapy and to function as designed. The observed performance of the Micra TPS remains within published expectations.1 No other Medtronic implantable device models are affected by this software display issue.
Software update Model SW022 version 8.1 is required to ensure that the correct remaining longevity estimate is displayed at all times during the life of the device. Without the software update, the displayed value during this period may remain static and reflect an over-estimation of the remaining longevity. Once the RRT voltage threshold is reached the correct remaining longevity estimate is once again displayed. Per labeling the time from RRT trigger to End of Service (EOS) is 180 days. The software display error was discovered internally. Through December 19, 2018 there have been zero (0) reports of this issue being observed in the field.
Through the end of calendar year 2019, it is estimated that 0.5% of early clinical devices would encounter an inaccurate longevity estimate during this period. The larger population of commercially implanted devices are not projected to encounter the issue until calendar year 2020. Updating programmers will eliminate this issue.
Note: A corresponding update to the CareLink Network Device Data Management Application Software was activated January 17, 2019 (coincident with the initiation of this communication). Therefore, any remote transmissions will already contain the software fix and the correct remaining longevity will be displayed through CareLink Network reports as of that date.

From the Programmer start-up screen CANCEL out of the Find Patient window and Select the Programmer icon along the righthand side of the programmer display:
Any CareLink transmission completed after January 17, 2019 will report the updated remaining longevity estimate. For in-clinic patients who have been interrogated via a programmer, the clinician can view the Battery and Device Measurements Report (Images 2a and 2b) and verify that the Software Application Model ID located in the lower-left corner of the report indicates “SW022 Software Version 8.1.”
