Dalkon Shield

from Wikipedia, the free encyclopedia
Drawing of the Dalkon Shield

The Dalkon Shield was an intrauterine device that was used very often in the 1970s, but later had to be taken off the market due to serious infections .

The shape of the Dalkon Shield was reminiscent of a flat bug with a large eye and five feet on either side. A lot of force was required to remove the pessary due to its shape. Therefore, the retrieval thread consisted of a braided fiber strand instead of a monofilament thread as with all other spirals. This retrieval thread was responsible for frequent and often dramatic infections, as bacteria could lodge in the braided thread and migrate into the uterus.

history

In 1970 the AH Robins Company bought the Dalkon Shield from the Dalkon Corporation. The Dalkon Corporation had only four shareholders, the inventors of the pessary, doctors Hugh J. Davis, Irwin Lerner, and Thad J. Earl, and their attorney Robert Cohn. In 1971 Dalkon launched the Dalkon Shield in the United States and Puerto Rico , accompanied by a large marketing campaign, although there were few and insufficient studies at the time. At the height of its spread, the Dalkon Shield was used by approximately 2.8 million women. By 1974 the Dalkon Shield claimed 17 lives.

With more than 300,000 lawsuits from users against the AH Robins Company, the Dalkon Shield was the largest case of damages claims after asbestos . As a result of the events, the confidence of American women and doctors in IUDs was permanently damaged for decades.
