Summary derived from FDA notice
Reason for Recall
As stated by FDA
Guidant has identified a pattern of premature battery depletion in devices manufactured with a single lot of capacitors from a single supplier. If function of this low voltage capacitor is compromised, the battery may deplete prematurely.
Recommended Action
Per FDA guidance
An Urgent Medical Device Safety Information & Corrective Action letter, dated May 12, 2006, was sent to physicians. The letter gave a description of the issue, clinical implications, rate of occurrence, devices affected and recommendation. Physicians are asked to follow-up with affected patients as soon as possible because ERI to EOL time may be shortened. Physicians are asked to contact Guidant for instructions on performing a baseline 'save to disk' and provide this information to Guidant. Guidant will be able to analyze the device memory data and estimate remaining longevity and provide individualized follow-up and replacement guidelines. Subsequent follow-up visits should continue to monitor for evidence of premature battery depletion.
