FDA Comments:

In May 2009, Medtronic sent letters to physicians and to patients with the affected Kappa and Sigma pacemakers. The company's June 10, 2009 news release and these letters contain the following recommendations:


  • Contact Medtronic (see above) to determine if your pacemaker is included in the affected group.
  • Contact your physician if you have one of the affected pacemakers.
  • Seek medical attention immediately if you experience symptoms such as fainting or lightheadedness.


  • Advise patients to seek medical attention immediately if they experience symptoms such as fainting or lightheadedness.
  • Consider device replacement for patients who are both pacemaker dependent and who have been implanted with a device in the affected subsets.
  • Continue routine follow-up in accordance with standard practice for those patients who are not pacemaker dependent.

Medtronic will offer supplemental device warranty if the device is not yet ready to be replaced.

The letter also provides physician and patient support. Letters were mailed to patients with registered devices beginning on May 27, 2009.

Class I recalls are the most serious type of recall and involve situations in which there is a reasonable probability that use of these products will cause serious injury or death.
