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.


Default Tool Image
This regulatory science tool (RST) serves as a reference dataset summarizing the engineering characteristics for orthopedic bone fixation devices (plates and screws) in pediatric patients.
HDI
This regulatory science tool is an open-access dataset containing raw inertial measurement unit (IMU) and sensorized insole data from individuals with Parkinson’s Disease (PD) and age-matched controls synchronized to a gait walkway reference system that can serve as a tool to assess novel algorithms deriving gait metrics through wearables and explore measurable connections between gait, PD severity, PD progression, and controls, thus leading to future clinical enhancements and treatments for patients.
EES
This regulatory science tool is a lab method for building a 5G network testbed to assess data transmission of medical device functions using 5G connectivity.
Digi Path
This regulatory science tool is a software program written in Python for analyzing whole slide images (WSIs) and assisting developers or pathologists in the assessment of machine learning algorithms used in digital pathology.
MXR
This regulatory science tool (RST) is a method for assessing the image quality of a head mounted display using the display’s transverse chromatic aberration characteristics to align the light measuring device to the eye-point/ center of the eye-box.
Cardiovascualar
This regulatory science tool is a lab method for performing platelet and leukocyte count assays per the <a href="https://www.iso.org/standard/63448.html">ASTM F2888-19 standard</a>, as a part of in vitro thrombogenicity assessment of blood-contacting medical device materials.
Ophthalmology Program Image
