Device to evaluate blood clotting under real flow conditions

Official title: Development of a Device for Evaluating Primary Hemostasis Under Whole Blood Flow Conditions

Run by Centre Hospitalier Universitaire Dijon · NCT03773159 · Data updated 2026-11-12

This study is testing a new device that simulates blood flow to see if it can better identify bleeding risks in people with von Willebrand disease or those on blood-thinning medications.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults with von Willebrand disease, major constitutional thrombopathy, or those on antiplatelet drugs who are receiving care at specific hospitals.

Probably not a fit

Patients who are pregnant, breastfeeding, or unable to provide consent will not benefit from this study.

What this trial studies

This study aims to develop a device that assesses primary hemostasis, which is the body's initial response to stop bleeding, under conditions that mimic actual blood flow. Current tests focus on individual components like platelets or von Willebrand factor, but do not account for the complexities of whole blood and flow dynamics. By using a device that simulates a blood vessel, the study seeks to better identify bleeding risks in patients with von Willebrand disease, major constitutional thrombopathy, or those on antiplatelet therapy. Participants will provide blood samples as part of routine testing to evaluate the device's performance.

Why it matters

Potential benefit: If successful, this device could lead to more accurate assessments of bleeding risk in patients, improving clinical decision-making and patient outcomes.

How similar studies have gone: While there are existing tests for hemostasis, this approach is novel as it aims to replicate physiological conditions more accurately than previous methods.
