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.


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.
Default Tool Image
This regulatory science tool comprises a model for conducting a retrospective analysis of COVID-19 intervention strategies.
Multi-Scale Cardiac Electrophysiological Modeling
This regulatory science tool comprises a computer model of a human action potential, which includes the effects of heart failure (HF) and the anti-arrhythmic drugs amiodarone (AM) and d-sotalol (DS).
CM&S Program Image
This regulatory science tool presents Python-based software for evaluating computer models that predict the number of COVID-19 deaths or hospitalizations expected in a specific locality.
CM&S Program Image
This regulatory science tool presents a method for assessing credibility of patient-specific computational models implemented in medical device software. 
Cardiovascualar
This RST, a “threshold-based” validation method, provides a means to determine an acceptance criterion for computational models. A “credible” computational model has the potential to provide a meaningful evaluation of safety in medical-device submissions [1,2].
MID
The Virtual Imaging Clinical Trials for Regulatory Evaluation (VICTRE) computer modeling pipeline is a set of tools that allow for the replication of clinical trials of in silico breast radiographic images for the evaluation of digital mammography (DM) and digital breast tomosynthesis (DBT) devices.
Cardiac-Elect_Model_Soft
A series of benchmark problems with known exact solutions that can be used to verify if tissue-level (e.g., ventricular, atrial) computational models of cardiac electrophysiology have been implemented correctly
MID
The Virtual Family provides detailed three-dimensional computational models of the human anatomy including an adult male, an adult female, and two children
Method of Manufact.
This study demonstrates the application of gold-standard method of manufactured solutions (MMS) code verification to verify a commercial finite element code for elastostatic solid mechanics analyses relevant to medical devices. The Python/SymPy code used to generate source terms is available as supplemental material.
Multi-Scale Cardiac Electrophysiological Modeling
Parsimonious (reduced complexity) model and software of the rabbit action potential amenable to large scale simulations of arrhythmias
VHT image
A computational modeling tool that provides first-pass estimation of the thermal effect produced in the vaginal wall by vaginal therapy devices.
MID
MC-GPU is a Monte Carlo simulation code that can generate synthetic radiographic images and computed tomography (CT) scans of realistic models of the human anatomy using fast Graphics Processing Unit (GPU) cards.
AI ML
Statistical tools (java GUI and R package) to analyze, size, and simulate multi-reader multi-case (MRMC) reader studies
Identifiability of Cardiac Electrophysiology Models
An approach for optimal experimental design and estimability analysis for mechanistic models of cardiac electrophysiology to determine their ‘identifiability’
CM&S Program Image
A finite element model of the human shoulder for simulating humeral abduction and calculating outputs such as contact force, contact pressure, contact area, stress, and strain.
MID
A software program written in Matlab for analyzing color performance testing data in endoscopy devices
Orthopaedics
Provides 16 mock intervertebral body fusion device (that is, a spinal cage) designs with three lattice structure implementations. Designs are provided in stereolithography (STL) file format so they may be fabricated using additively manufacturing (AM) technologies.
Materials Program Image
Predicts the impact of extraction conditions, sample geometry and material properties on extraction test efficiency
