Use:Pacemakers of this type are surgically implanted in persons with a heart disease affecting the heart’s ability to generate and conduct electrical impulses. These devices generate small electrical impulses that trigger the heartbeat.
Recalling Firm:

Guidant Corporation – CPI Division

4100 Hamline Ave. N.
Saint Paul , Minnesota 55112-5700

Reason for Recall:A seal within the devices can leak, allowing moisture to affect the electronic circuits. This defect can cause the pacemakers to fail to provide pacing or can cause a rapid heart rate. Other unexpected device behaviors are also possible. The problems may occur without warning and can lead to loss of consciousness, and possibly heart failure and death.
Public Contact:Consumers with questions may contact Guidant Corporation at 1-866-GUIDANT (1-866-484-3268).
FDA District:Minneapolis
Advice to Users:
  • If you believe you are pacemaker dependent, contact your physician soon to discuss your treatment options.
  • Continue your normal doctor appointments.
  • If you experience symptoms of shortness of breath, dizziness, lightheadedness, loss of consciousness, or a prolonged fast heart rate, you should consult with your physician or go to the emergency room immediately.
  • If you are not sure which model you have, or if you have other questions regarding your device, consult with your physician.
