COBRA-OS® has arrived to the Baltics! Developed by Canadian manufacturer Front Line Medical Technologies, this aortic balloon occlusion system allows for faster and safer control of bleeding in trauma patients.
COBRA-OS® (Control Of Bleeding, Resuscitation, Arterial Occlusion System) has a clear purpose: to enable emergency responders to perform the REBOA procedure in time-critical situations, achieving effective control of bleeding while minimizing the risk of complications arising from the procedure.
What is a REBOA procedure?
REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) is a minimally invasive procedure in which the aorta is occluded using a ballon to stop acute bleeding and redirect blood flow to vital organs. For selected patients, the REBOA procedure is a valid alternative to highly invasive thoracotomy.
The REBOA procedure is primarily recommended in the following cases:
- NCTH, or massive internal bleeding in the thoracic area, where no external compression can be applied
- Thoracic trauma with massive intra-abdominal or pelvic hemorrhage
- Acute postpartum hemorrhage that cannot be treated with standard methods
- Trauma-induced cardiac arrest
- Field conditions in military, tactical, and disaster medicine
- In situations where the transit time to the hospital takes a long time and an earlier intervention is crucial
Why choose COBRA-OS® for REBOA?
🔴4 Fr diameter: the one and only
The smallest-diameter REBOA solution to date! 4 Fr means less tissue damage, fewer complications, and faster recovery.
🔴Partial REBOA (pREBOA) opportunity
pREBOA = Partial REBOA allows for partial balloon inflation, maintaining some blood flow to the lower limbs. It is used to reduce ischemia and reperfusion damage when the patient’s condition permits this treatment.

🔴 Compact, clearly labeled and user-friendly
The set contains everything needed for the procedure. The solution is designed for rapid deployment in time-critical situations, allowing the product to be used even with minimal preparation time and under challenging outdoor conditions.

Who is COBRA-OS® meant for?
- For Trauma Departments and Trauma clinics
- For Emergency Medicine Departments
- For departments of Anaesthesiology and Intensive Care
- For Maternity Wards
- For military and tactical medicine units, TCCC
- For paramedics in situations where a patient needs to be stabilized prior to reaching the hospital
*The REBOA procedure is internationally recognized and evidence-based. Among others, Prof. Peep Talving has also introduced the REBOA technique (in the journal Eesti Arst “Nüüdisaegne traumakäsitlus“) and interest in this method is steadily growing within our healthcare system. Semetron is the official representative of COBRA-OS® in Estonia, Latvia, and Lithuania.
