Toy balloon in "Swiss Family Robinson" (1813) and in "Moby Dick" (1851). The first rubber balloons were made by Professor Michael Faraday in 1824 for use in his experiments with hydrogen at the Royal Institution in London. "The caoutchouc is exceedingly elastic", he wrote in the Quarterly Journal of Science the same year.

Bakri balloon "temporary control or reduction of postpartum hemorrhage when conservative management of uterine bleeding is warranted." One study in Finland involving 50 patients recorded an overall success rate of 86% when using the Bakri Balloon in managing PPH. A German study involving 20 patients cited an overall success rate of 90% when the balloon is used in combination with B-Lynch sutures. Both the International Federation of Gynaecology and Obstetrics (FIGO) and the International Confederation of Midwives (ICM) have approved the balloon as one of the primary support tools in treating PPH.
