FDA CDRH – Medical Officer (Gastroenterologist) SME Position Description

The mission of the FDA Center for Devices and Radiological Health (CDRH) is to protect and promote the public health. CDRH assures that patients and providers have timely and continued access to safe, effective, and high-quality medical devices and safe radiation-emitting products.

The Office of Product Evaluation and Quality (OPEQ) is the office responsible for the evaluation of pre- and post-market submissions from the medical device industry. The office plans, coordinates, and renders Agency decisions regarding the approval, denial, and withdrawal of approval for companies to market medical devices in the United States. OPEQ also authorizes the conduct of clinical trials of unapproved medical devices under the Investigational Device Exemptions (IDE) program. The data gathered in these clinical studies is frequently used to support market authorizations.

Tunnell Government Services, Inc. is providing professional and scientific services to the CDRH with expert consultants with scientific expertise in the regulation and approval and of medical devices.

Provides expert clinical judgment related to post-market and compliance reviews (e.g., adverse event reports, recalls, allegations, Establishment Inspection Reports).
