The history of birth control is unfortunately filled with unfortunate defects that have injured women. Dalkon Shield became one of the largest mass tort lawsuits of all time. IUD insertion had been viewed as an easy way for a reversible form of birth control that did not have the same hormonal effects.
However, intrauterine devices have proven dangerous, as IUD removal work does not always go as planned. A IUD device called Paragard was supposed to change that. However, the IUD removal process has often gone awry, causing women serious injury.
Paragard is made by a company called CooperSurgical Inc. The original manufacturer was Teva Pharmaceutical, but Teva sold the Paragard product line to Cooper for $1.1 billion in 2017. The product has been on the market since 1984.
