Reason for Recall:

The firm issued a letter to customers on Sept. 11, 2012 describing the problem and provided instructions for correction. Certain Samaritan® 300/300P PAD devices have been found to intermittently turn on and off, which may eventually deplete the battery.  In addition and separately, certain Samaritan 300/300P PAD devices containing early versions of the battery management software may misinterpret a temporary drop in battery voltage as signaling a low battery resulting in the device turning itself off.  A device experiencing either condition could be unable to deliver therapy during a cardiac event.

Public Contact: Consumers with questions may contact the company at 1-877-877-0147 between the hours of 8:00am and 5:00 pm ET and email at

FDA District: Philadelphia

FDA Comments:

HeartSine has requested that customers follow the instructions detailed in their letter dated Sept. 11, 2012 to ensure that affected devices are able to provide therapy if a sudden cardiac arrest event occurs.

No deaths or injuries have been reported to date associated with the on/off issue.  To date, HeartSine has received five reports of death for which the company has not been able to rule out the possibility that the events may have been related to the battery management software issue.

Class 1 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 adverse health consequences or death.

Health care professionals and consumers may report adverse reactions or quality problems they experienced using these products to MedWatch: The FDA Safety Information and Adverse Event Reporting Program either online, by regular mail or by FAX.
