Medical Device Submissions

Medical devices are required to undergo FDA review and approval before being marketed for sale in the United States.   In order to achieve this approval, the appropriate medical device application(s) must be submitted to the Agency.  The applicable application and regulatory requirements vary depending on the device’s classification.  As such, the successful classification of your device is imperative.

The Weinberg Group has the knowledge and expertise to help you determine the correct classification for your device and assist with the production and submission of your application.

An Investigational Device Exemption (IDE) allows a medical device to be used in a clinical study for the purpose of collecting the safety and effectiveness data needed to support a marketing application. Analogous to an Investigational New Drug (IND) application for drugs, manufacturers of significant risk medical devices must obtain IDE approval prior to initiating a clinical study. However, unlike IND applications, there are no formal, preprinted forms for IDE submissions; only certain information that must be included in the submission. This can make preparing an IDE submission extremely challenging and stressful. We can help ease the stress working with you to prepare and submit a complete IDE application.

Investigational use also includes clinical evaluation of certain modifications or new intended uses of legally marketed devices. Unless the device is exempt, all clinical evaluations of investigational devices must have an approved IDE before the study is initiated. Furthermore, clinical evaluation of an unapproved device requires:

  • An investigational plan approved by an institutional review board (IRB)
    • If the study involves a significant risk device, the IDE must also be approved by FDA
  • Informed consent from all patients
  • Labeling stating that the device is for investigational use only
  • Monitoring of the study
  • Intended use, and
  • Required records and reports

There are many additional requirements involved in obtaining IDE approval from the FDA. Navigating this landscape can be tricky and requires the knowledge and skill of a regulatory and compliance expert. We are the expert you need. We will assist you in the development and submission of a complete IDE application for your medical device, maximizing the likelihood of FDA approval.

According to section 513(g) of the FD&C Act, device manufacturers may submit a written request to obtain the Agency’s views regarding device classification and the regulatory requirements applicable to their device.

513(g) requests must be submitted to the FDA in writing and are appropriate in situations where the device manufacturer can’t easily determine which class their device fits into and would like to confirm their decision with the FDA. These requests allow manufacturers to obtain additional feedback from the Agency and help Sponsors determine the best regulatory pathway for their medical device.

As with any FDA submission, completing a 513(g) Request for Information is a challenging task and should be completed by a seasoned professional. The Weinberg Group can help you determine the best classification for your device, as well as assist in the development and submission of a 513(g) Request for Information. We will work with you to ensure your request is complete and contains all required information, which includes:

  • Cover letter
  • Description of the device
  • Description of what the device is to be used for
  • An investigational plan approved by an institutional review board (IRB)
    • As applicable, any labeling or promotional material of a similar, legally marketed device (if available)

A 510(k) is a premarket submission which demonstrates that the device in question is substantially equivalent to a legally marketed medical device and is not subject to a PMA (premarket approval). 510(k) submissions are the most common type of medical device submission, and FDA-clearance of this application is required before applicable devices can be marketed for sale in the United States.

The Weinberg Group has substantial experience developing and submitting 510(k) applications. We have compiled hundreds of 510(k) submissions over the last 35 years. We have a proven track record of success with the FDA and are highly qualified to assist you through the medical device submission process.

Premarket Approval (PMA) is the regulatory and scientific process used by the FDA to review and evaluate the safety and effectiveness of certain Class III medical devices. Medical devices that are considered high-risk and must obtain an approved PMA from the FDA before the device can be marketed for sale in the United States.

PMA is the most rigorous of all the medical device submissions, and FDA approval is based on the scientific evidence presented in the submission to demonstrate that the device is safe and effective for its intended use(s). Developing a PMA application is extremely complex and time consuming. Due to the Agency’s requirement that Sponsors provide clinical evidence of the medical device’s safety and effectiveness, developing a successful PMA requires a significant amount of planning, preparation, and resources. Getting the submission right the first time is critical to the sale of your device, and we can help you do just that.

We work with you through every step of the PMA process. Together we will compile an application that is ready for review by the FDA.

Wondering whether the De Novo pathway is right for your medical device? You’re not alone, but we’re here to help. Depending on how you answer the following questions, a de novo submission may be the best option for your device:

  1. Is your product a novel medical device?
  2. Does your device present a low or moderate risk profile?
  3. Do any predicate devices exist?

The De Novo process provides a way to classify low to moderate-risk, novel medical devices. If you have a risk-based strategy and a De Novo determination from the FDA, it is possible for you to receive approval for your novel medical device without going through the costly and time-consuming PMA process.

However, obtaining a De Novo determination is dependent on your ability to present the general controls or general and special controls which provide reasonable assurance of the safety and effectiveness of the device. De Novo determinations are made by the FDA on a case by case basis, but The Weinberg Group can help you get there. We will assist you through the entire submission process, making sure your application contains the most appropriate and relevant information.

Submitting a De Novo request can be difficult and confusing, presenting various roadblocks along the way. We have what it takes to help you overcome those barriers and compile a complete and error-free submission for your medical device.

A Humanitarian Use Device (HUD) is a medical device intended to benefit patients in the treatment or diagnosis of a disease or condition that affects less than 8,000 people in the U.S. each year. In order to receive HUD designation from the FDA, various data and documentation must be presented to prove that the device meets the standards required for a HUD designation.

Once the FDA has granted the HUD designation, the Sponsor may then develop and submit a Humanitarian Device Exemption (HDE) marketing application. Obtaining FDA approval for these devices can be difficult for even the most seasoned experts because it is dependent on the ability to find and present the right documentation and data. Seeking the assistance of a regulatory consultant is your best bet when preparing a marketing application. The Weinberg Group is qualified to assist you with all facets of drug and device development and can help you achieve successful interactions with the FDA at every step of your medical device submission.


The Weinberg Group has 37 years of regulatory consulting experience and will use our expertise and relationship with the FDA to help achieve approval for your medical device. We can help you determine whether an IDE, 513(g), 510(k), PMA, De Novo, or HUD/HDE classification is right for your medical device, and we’ll guide you through every step of the appropriate submission to ensure a successful interaction with the agency.
