SUPPLEMENTARY INFORMATION:

I. Background

There has been an increased interest in the use of CM&S studies as a tool to support medical device applications, as evidenced by the increase in the number of computer modeling test reports submitted in medical device applications. The Center for Devices and Radiological Health (CDRH) recognizes that use of CM&S studies are an innovative means to design, develop, and evaluate medical devices, and has held five public meetings on the topic in recent years. Information regarding the most recent meeting, “FDA/NIH/NSF Workshop on Computer Models and Validation for Medical Devices,” June 11-12, 2013, is available at: http://www.fda.gov/​MedicalDevices/​NewsEvents/​WorkshopsConferences/​ucm346375.htm.

CM&S studies have traditionally been used in the areas of fluid dynamics (e.g., shear stress and stagnation calculations in ventricular assist devices), solid mechanics (e.g., maximum stress locations in a hip implant), electromagnetics and optics (e.g., radiofrequency dosimetry in magnetic resonance imaging, fluence for fiber optic spectroscopy devices), ultrasound propagation (e.g., absorbed energy distribution for therapeutic ultrasound), and thermal propagation (e.g., radiofrequency and laser ablation devices). The purpose of this draft guidance document is to provide recommendations to industry on the formatting, organization, and content of reports of CM&S studies that are used as valid scientific evidence to support medical device submissions. Moreover, this draft guidance is intended to help improve the consistency and predictability of the review of computational modeling and simulation studies and to better facilitate full interpretation and complete review of those studies.

The draft guidance provides a general outline of information that should be included in a CM&S report, written in general terms to capture reporting for any modality. The guidance also includes five subject matter appendices that provide more background, structure, and specific terminology for modeling and simulation modalities that are widely used in regulatory submissions, including fluid dynamics and mass transport; solid mechanics; electromagnetics and optics; ultrasound; and heat transfer.

II. Significance of Guidance

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the Agency's current thinking on “Reporting of Computational Modeling Studies in Medical Device Submissions.” It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statute and regulations.

III. Electronic Access

IV. Paperwork Reduction Act of 1995

This draft guidance refers to currently approved collections of information found in FDA regulations. These collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in 21 CFR part 812 have been approved under OMB control number 0910-0078; the collections of information in 21 CFR part 807 subpart E have been approved ( printed page 3212) under OMB control number 0910-0120; collections of information in 21 CFR part 814 subpart B have been approved under OMB control number 0910-0231; and collections of information in 21 CFR part 814 subpart H have been approved under OMB control number 0910-0332.
