  • Reason
    Medtronic has identified an issue with the sensitivity of an algorithm used in the reveal linq icm that may prematurely trigger the rrt alert in some devices. as of february 12, 2016, medtronic has observed an occurrence rate of 0.45% of devices experiencing this issue. battery capacity is not affected and the device will continue to support data collection and manual data transmissions. as stated in reveal linq labeling, the typical device will experience an average of 3 years longevity (refer to the device labelling for the corresponding use conditions). as part of the normal behavior of the device, 30 days after rrt status is reached, reveal linq devices will display an end of service (eos) status at which time the device disables automatic wireless alerts and transmissions. thereafter, patients will still be able to send remote manual transmissions for clinics to receive alerts and stored device data. due to the design of the rrt algorithm, devices are not susceptible to this issue until 200 days (6.5 months) post-implant. as of february 12, 2016 the earliest reported occurrence of rrt is 7.3 months post-implant, with median implant to rrt duration of 16.5 months. .

Medtronic noted that these communications can include letters, emails, calls, press releases, physician notifications and social media postings, as well as informing the FDA and other regulators of the actions.
