Product Lifecycle

The life cycle of Medical DevicesFDA Regulatory Strategic Planning

What are mdi’s FDA Regulatory Strategic Planning Services?

Given that we understand the product development process, the FDA submission process and the interplay between these processes, we can craft a regulatory strategy based on your situation. This strategy will include thinking through what actions you take, what you document, what submission process to take, how to structure your clinical trial, etc.

How can mdi assist you?

economic value of a carefully thought out FDA regulatory strategy. Because of our experience and understanding of the FDA, through careful planning we can help you to:

  1. Minimize the time it takes to get through the submission process, by correctly laying out the steps required and preparing your submission appropriately
  2. Minimize the cost spent in the submission process by defining a specific roadmap that allows you to identify the correct type of submission, eliminate the typical clinical trial management mistakes and reduce quality system implementation errors
  3. Maximize your product revenues by enabling you to sell your product while the FDA reviews your files
  4. Optimize your competitive situation by thinking through how your submission type and structure will effect your competitors, suppliers and customers

Clinical Trial Management

What are mdi’s Clinical Trial Management Services?

Our services include developing the clinical protocol, setting up and interacting with the IRB (Institutional Review Board), submitting the IDE (Investigational Device Exception), recruiting and working with the investigator, monitoring the trials, data gathering and analysis, project management, and statistical analysis.

What are mdi’s 510(k)/PMA/DMF Submission Services?

  • A 510(k) is a required application that must be sent to the FDA in order to market a product in the U.S. A 510(k) must be submitted for certain Class I devices as well as for Class II and certain Class III devices. It must be submitted for products that have been marketed after May, 1976 (when the regulations took effect) and for products where a substantially equivalent (SE) product can be found in the market.
  • A PMA (Premarket Approval) is a required application that must be sent to the FDA in order to market a product in the U.S. A PMA is required for certain Class II and Class III devices where no substantially equivalent product currently exists.
  • A DMF (Device master file) is a file that is submitted to the FDA that includes technical, clinical, and safety information about a medical device component or material. If you are a component maker, your customers may desire a DMF from you.
  • mdi guides clients through the entire application preparation and submission process.

How can mdi assist you?

  • Correctly submitting any of these documents to the FDA is both science and art. Unless you have extensive experience in this field, you may encounter some difficulties that you did not anticipate. For 510(k)s we have observed many of the following problems
    · Cover letters that are unclear, poorly written, highly technical, contradict application and/or include unsubstantiated claims
    · Incorrect classification of a device (e.g. PMA submission that should have been a 510(k)
    · Incorrect comparisons of device vs. predicate devices
    · Poor presentation of clinical trial data
    · Little understanding of the clinical trial requirements
    · Limitations and counter indications that undermine product safety or efficacy
    · Advertising material that doesn’t match intended use
    · Underestimation of the amount of communication and relationship-building that needs to be done with the FDA reviewer
  • If you supply us with the following information concerning your device, mdi’s specialists can provide you the best way to approach the FDA – either 510(k) or PMA, your estimated time for FDA review, and an estimate of the testing and submission costs:
    · Intended use of your device
    · What legally sold device that you are claiming that your device is substantially equivalent to
    · The risks and hazards associated with the use of your device
    · The materials your device is made with
  • Our staff has in-depth knowledge on how to submit these applications and has developed strong relationships with the FDA over the last 25 years. Given our experience, we can work with you to successfully achieve approval for your submission whether you want us to do it completely or for us to simply guide you through the process. Our results of over 500 successful approvals, speak for themselves.

FDA Quality System Strategy

What are mdi’s FDA Quality System Strategy Services?

  • Assuring FDA compliance to quality system requirements is critical for all medical companies. The quality system requirements are defined by QSR (Quality System Regulations) /cGMP (Current Good Manufacturing Practices) guidelines which are specified by the FDA.
  • The process by which to achieve compliance to these requirements is different for each company. For example, large companies may need to prioritize geographically-different operations based on size/importance and implement systems accordingly. A smaller company may need to prioritize which elements of the quality system to implement first (e.g. work instructions, design control) in order to get in compliance quickly.

How can mdi assist you?

Making these types of decisions requires thought and planning because these decisions will affect the speed and cost of the total implementation, potential savings that could be realized through a quality system implementation and the level of comfort the FDA will have that you are implementing a compliant quality system.
