The U.S. Food and Drug Administration may have greatly underestimated the number of fetal deaths among women who became pregnant after using Bayer AG's Essure contraceptive device, according to a private analyst who combed through the agency's public database.
Madris Tomes, founder and chief executive officer of Device Events, said her analysis of thousands of adverse events from the agency's website shows 303 fetal deaths were linked to Essure
The agency is expected this month to decide whether to restrict use of the device, change the product's label or recommend additional clinical trials. The FDA also cited four adult deaths for reasons such as infection and uterine perforation.
