Testing a new magnetic sensor for measuring blood flow in leg arteries
Official title: Validation Study of a Magnetic Sensor in Arterial Flow Recording, Compared With the Reference Method (Echodoppler), at Various Peripheral Arterial Sites
Run by University Hospital, Montpellier · NCT06274697 · Data updated 2026-11-12
This study is testing a new magnetic sensor to see if it can measure blood flow in the leg arteries of patients with lower extremity artery disease better than traditional methods.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include hospitalized patients aged 18 and older with lower extremity artery disease or those without it.
✕Probably not a fit
Patients with metal implants near the sensor's area of use or those requiring additional hygiene precautions may not benefit from this study.

What this trial studies
This study evaluates a prototype magnetic sensor designed to measure arterial flow in patients with lower extremity artery disease. The sensor detects weak magnetic currents generated by blood flow, aiming to provide a non-invasive and cost-effective alternative to traditional Doppler ultrasound methods. Patients hospitalized in the Heart-Lung Unit of Montpellier University Hospital will be assessed for their eligibility based on specific criteria. The goal is to validate the sensor's effectiveness compared to established methods.
Why it matters
Potential benefit: If successful, this could offer a new, accessible diagnostic tool for screening peripheral arterial disease.
How similar studies have gone: While similar technologies have been explored in cardiac applications, this specific use in peripheral circulation is novel and untested.
