Humanitarian Use Device Studies

A Humanitarian Use Device (HUD) is a device that is intended to benefit patients by treating or diagnosing a disease or condition that affects or is manifested in fewer than 4,000 individuals in the United States per year.  IRB approval is required in all cases, but physicians and sites do not collect research data and are not compensated monetarily for the regulatory support they offer.  These devices are offered for the benefit of the patient only.

If you think you may qualify for one of these studies, please contact CNI’s Research Department at 303-806-7416 or
