New 'Neural Tourniquet' Uses Nerve Stimulation to Halt Bleeding
Researchers have developed a device that stimulates the vagus nerve to promote blood clotting, potentially reducing bleeding during surgeries. This technology, known as transcutaneous auricular neurostimulation (tAN), has shown promising results in early trials, suggesting a "neural tourniquet" effect. If further clinical trials confirm its efficacy, this non-invasive method could be used to prevent excessive bleeding in surgical patients, addressing a significant unmet need in medical procedures.
