Feasibility Clinical Study of the Alma System in Treating Primary Postpartum Hemorrhage

10 subjects, first in woman trial with ethics committee oversight. Women who experienced postpartum hemorrhage will be treated with the Alma System, which aims to rapidly reduce or stop the bleeding by targeting the primary cause: uterine atony. The primary objective is to verify the safety of the Alma System in humans by: 1. Ensuring the absence of serious adverse events (SAEs) related to the use of the Alma System during and after the procedure. 2. Evaluating any observable damage to the uterus, cervix, or vagina due to the use of the Alma System. 3. Evaluating the occurrence of uterine inversion or folding during the use of the Alma System. The secondary objectives include evaluating: 1. The ability to easily place the Alma System trans-vaginally. 2. The ability to connect the Alma System to a vacuum source and maintain the desired negative pressure. 3. The ability of the Alma System to contract the uterus to a level that reduces or stops blood loss and avoids further non-surgical and surgical intervention. 4. The time from insertion and start of negative pressure to a visible reduction in blood loss.
