Manufacturer Narrative

A replacement freestyle flex breast pump was sent to the customer and return of her original pump was requested for testing/evaluation.In follow up with a complaint handler between 07/09/2020 and 07/16/2020, the customer indicated that she had been using the new freestyle flex pump and it seemed to be working fine.Additionally, she stated that the pain was related to mastitis, which she was diagnosed with in april and for which she was prescribed an antibiotic and ibuprofen for pain.The device was returned without the customer's parts and accessories; therefore, it was evaluated with a medela lab kit 07/23/2020 and, though an intermittent noise was identified during the evaluation, the device passed suction and cycle specifications.Refer to attached product evaluation.This is consistent with the fact that the customer did not allege a failure related to the device, but reported pain (due to mastitis) when using the device.Based on the results of ca11-001, it cannot be definitively concluded that the pump caused or contributed to the customer's mastitis.The estimated incidence of mastitis in lactating women, whether using a breast pump or not, according to published clinical literature can be as high as 33%.In fact, clinical guidelines suggest the use of a breast pump to facilitate withdrawal of breast milk during bouts of mastitis.The complaint rate of mastitis across all reported failures, across all medela breast pumps, is 0.008% for the period of january 2013 to august 2017.Mastitis is usually a benign, self-limiting infection with few consequences for the suckling infant.The risk of mastitis is higher among women who have breastfed previously, especially those with a history or mastitis." riordan & wambach, 4th ed.P.294: breastfeeding and human lactation.Mastitis requires prompt medical attention for the mother for pain relief and prescription antibiotics to avoid progression to overwhelming sepsis.
