  • Extra notes in the data
    We recommend immediate replacement of the charger for patients who report or have reported excessive heating during charging: - For other patients, replacement of the charger is suggested at the next visit. - After the replacement, the proper operation of the Eon Mini LE Model 3722 Charger must be confirmed. In case of difficulties with the operation of the Eon Mini Model 3722 Charger, due to the depth of the implant, the patient should continue to use the Mini Model 3721 Eon Charger (eg older charger), following the precautions provided in the July letter of 2012. These precautions are as follows: - If the temperature at the implant site becomes uncomfortable during loading: - Stop the recharge until the discomfort disappears and then continue recharging; - Reposition the antenna over the implant site; - Consider a more frequent and shorter recharge; - If the temperature is still uncomfortable, please contact your doctor, SJM representative, or St. Jude Medical Brazil technicians. - Avoid pressing the antenna between the body and a surface that can retain heat, such as a bed or a chair. - The use of topical anesthetics, balsamic medicine, and / or pain relief adhesives at the implant site before or during loading is not recommended as it may reduce the ability to perceive heat or excessive heating near or at the implant site. - Do not carry the device while sleeping. - Do not consume alcohol immediately before or during loading.

  • Manufacturer comment
    “We are in constant communication with regulatory agencies and competent authorities worldwide which allows us to implement global recalls or in-country communication quickly and effectively,” Abbott, which now owns St. Jude Medical told ICIJ in a statement. In addition to sending global notices to physicians worldwide, we also make sure that product advisories are available online and classification of product recalls and product advisories are determined by global regulatory bodies which can impact the timing in any given country. MD companies follow varying regulations in different countries. In come countries software is not regulated so a recall in one country related to software would not be classified as a recall or field action in another. In addition, review cycles within the regulatory process can be different in each country which can impact communication and recall timing.
