Regulatory Science Tools Catalog

The Regulatory Science Tools Catalog provides a peer-reviewed resource for use where standards and qualified Medical Device Development Tools (MDDTs) do not yet exist. These tools do not replace FDA-recognized standards or MDDTs. This catalog collates a variety of regulatory science tools that the FDA's Center for Devices and Radiological Health's (CDRH) Office of Science and Engineering Labs (OSEL) developed. If you are considering using a tool from this catalog in your marketing submissions, note that these tools have not been qualified as Medical Device Development Tools and the FDA has not evaluated the suitability of these tools within any specific context of use. You may request feedback or meetings for medical device submissions as part of the Q-Submission Program.


AO-qOCTA
This regulatory science tool (RST) is a quantitative optical coherence tomography angiography (qOCTA) method to measure the absolute velocity of individual blood cells within retinal microvasculature and map 3D flow rates.
Experimental force-displacement data
This regulatory science tool (RST) is computational material model of polyurethane bone foam with a density of 20 pounds per cubic foot (PCF), which can be implemented in a finite element analysis application.
ICGA
This regulatory science tool (RST) is a lab method for absolute vessel caliber and retinal blood flow velocity measurements in humans using a high-resolution (spatial and temporal) multimodal adaptive optics system with scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT).
Fixture
This regulatory science tool presents a laboratory method to assess the mechanical integrity of anterior vertebral body tethering (AVBT) devices.
CFD Simulation Through Generalized Cardiovascular Medical Device Geometries
The tool provides hemolysis data obtained from inter-laboratory bench experiments within generic and simplified device geometries. Modelers can use the data to perform early-stage evaluation of their computational fluid dynamics (CFD) model of hemolysis.
