  • Extra notes in the data
    Medtronic does not recommend the prophylactic replacement of SynchroMed II pumps with the previous battery design because of the estimated low occurrence rate, the presence of pump alarms, and the risk associated with replacement surgery. This opinion has been reviewed and is supported by the panel of specialized external physicians. However, proper consideration should be given to the medical needs of each patient. When critical and non-critical alarms listed below occur, Medtronic strongly recommends that replacement surgery be scheduled as quickly as possible for these patients.
