Summary

This study tests a device called the Alma system for women who have severe bleeding after childbirth that does not stop with standard treatments. About 50 women who experience heavy bleeding after vaginal or C-section delivery will be enrolled. If usual care fails, the Alma system is used to try to control the bleeding. Participants are followed until 6 weeks after birth to check safety and effectiveness.
