The device, which is being developed by Maria Palasis of Arsenal Medical, Inc. in the U.S, can be inserted into the uterus following childbirth and expands to control bleeding. The device is inexpensive and primarily made of a homeostatic foam material. Arsenal Medical is a company that specializes in BioActive composites, in non-medical shorthand, these are materials that interact with the human body for a clinical purpose. The Gates Foundation is funding the development of this new device that could control postpartum bleeding, the leading cause of maternal death in the developing world. We will follow the development of this exciting device.
