The Early Bird Bleed Monitor System (EBBMS) is comprised of a standard vascular access sheath with embedded sensors that measure the electrical resistance across the blood vessel. By sensing a change in the vessel’s electrical resistance, the EBBMS is designed to detect and monitor bleeding from a blood vessel accidentally injured during endovascular procedures. When there is a vessel injury at the femoral access site, blood begins to accumulate outside the vessel, causing a change in impedance; a user interface display alerts the user to the change in impedance and a potential bleeding complication. The EBBMS is sensitive enough to detect as little as 30 mL of blood loss.
