Medical Device Amendments of 1976 to the FF,D,&C Act
  • May 28, 1976
  • Defined a device (201(h) of the Act)
  • Required classification of device types legally on the market at that time
  • Led to classification of approximately 1,700 different generic types of devices and grouped them into 19 medical specialties
  • Required premarket review of devices
What is a 510(k)
  • Premarket Notification
  • Section 510(k) of Federal Food, Drug, & Cosmetic Act
  • 21 CFR 807 Subpart E
  • Marketing Clearance Application
  • Allows FDA to Determine Substantial Equivalence (SE)
  • “The” classification process for a device
What a 510(k) Is Not
  • A Form
  • Establishment Registration
  • Device Listing
  • Premarket Approval (PMA)
510(k) & Classification
  • A 510(k) is the classification process for individual post-amendment devices by:
    • Finding the device substantially equivalent (SE) or
    • Finding the device not substantially equivalent (NSE)
Pre-amendment vs. Post-amendment

The F F, D, & C Act divided the arena of medical devices depending on when the devices were introduced into commercial distribution:

  • Pre-amendments Devices (pre-May 28, 1976)
    • Exempted (with conditions) from marketing clearance
      VS.
  • Post-amendments Devices (post-May 28, 1976)
    • Requires marketing clearance
What is a Predicate? 21CFR Part 807.92(a)(3)

An identification of the legally marketed device to which the submitter claims equivalence. A legally marketed device to which a new device may be compared for a determination regarding substantial equivalence is

a device that was legally marketed prior to May 28, 1976, or a device which has been reclassified from class III to class II or I (the predicate),

or a device which has been found to be substantially equivalent through the 510(k) premarket notification process;

What is a Device Type?
  • 21 CFR 860.3(i)
    • Generic type of device means a grouping of devices that do not differ significantly in purpose, design, materials, energy source, function, or any other feature related to safety and effectiveness, and for which similar regulatory controls are sufficient to provide reasonable assurance of safety and effectiveness.
Regulatory Classes

Three Regulatory Classes (level of control based on risk):

  • Class I – General Controls
  • Class II – General Controls & Special Controls
  • Class III – General Controls and Premarket Approval
Classification
  • Classification regulations for individual device types are found in 21 CFR Parts 862-892
  • Regulations describe the device type as it existed Prior to May 28, 1976
  • New indications for use or new technologies are assigned new product codes
  • Classification regulations for individual device types found in 21 CFR Parts 862-892
    Example:
    Part 872 – Dental Devices
    138 Device Types, e.g.,:
    Sec. 872.4760 Bone plate. (a) Identification. A bone plate is a metal device intended to stabilize fractured bone structures in the oral cavity. The bone segments are attached to the plate with screws to prevent movement of the segments. (b) Classification. Class II.
Substantially Equivalent (SE) Ltr

Classification Regulation appears on all SE Letters and are available on the Internet

Establish Equivalence to:
  • A legally marketed device (a predicate*) that does not require a PMA, i.e., a:
    • Preamendments device*
    • A device found by FDA to be Substantially Equivalent (SE), or
    • A reclassified device*
      *21 CFR 807.92(a)(3)
Device is Substantially Equivalent (SE)
  • If:
    • In Comparison to a legally marketed device, it:
      • Has the same intended use, and
      • Has the same technological characteristics as the predicate device,
    • Or . . . . . . . . . . . . .
    • Has the same intended use, and
    • Has different technological characteristics and the information in the 510(k):
      • Does not raise new questions of safety and effectiveness, and
      • Demonstrates it is at least as safe and effective as the predicate
FDA finds the device Substantially Equivalent (SE)?
  • NO - PMA, Application or De Novo
  • YES - To Market
Not Substantially Equivalent (NSE)
  • There is no predicate device
  • Has a NEW intended use
  • Has different technological characteristics compared to the predicate device and raises a new type question of safety and effectiveness
    • All examples above required no review of data and will require PMA or De Novo
  • Does not demonstrate that it is at least as safe and effective as the predicate
    • The example above required review of data and is eligible for a new 510(k) with new data
  • Approximately 3% are found NSE
  • Data is looked at last in the 510(k) regulatory process
  • FDA usually asks for additional information at least once prior to determining the device is NSE for lack of data
510(k) & Classification
  • Finding the device not substantially equivalent (NSE)
    • automatically places device into class III and requires:
      • PMA; or
      • Reclassification before marketing
Modifications
Licensing of 510(k)s
  • A firm may not BOTH manufacture and distribute a device without their own 510(k)
  • (21 CFR 807.85(b)(2))
Finished Device 820.3(l) – Quality System Regulation
  • 820.3(l) Finished device means any device or accessory to any device that is suitable for use or capable of functioning, whether or not it is packaged, labeled, or sterilized.
  • Finished device in final form for sale to an end user is subject to 510(k) requirements
"Unfinished Device" for purposes of 510(k)
  • If not in final form, OR in final form but NOT for sale to an end user, is not subject to the 510(k) requirements
Accessories & Components
  • Component (820.3(c)) - Component means any raw material, substance, piece, part, software, firmware, labeling, or assembly which is intended to be included as part of the finished, packaged, and labeled device.
  • Accessory—”extras” (not defined in the regulations)
  • Accessories/components to a device take on the same classification as the "parent" device unless they are separately classified
  • A finished accessory or a finished component sold to an end user, is subject to 510(k) requirements.
