SUPPLEMENTARY INFORMATION:
I. Background
Upon request, FDA has classified the screw sleeve bone fixation
device as class II (special controls), which we have determined will
provide a reasonable assurance of safety and effectiveness. In
addition, we believe this action will enhance patients' access to
beneficial innovation, by placing the device into a lower device class
than the automatic class III assignment.
The automatic assignment of class III occurs by operation of law
and without any action by FDA, regardless of the level of risk posed by
the new device. Any device that was not in commercial distribution
before May 28, 1976, is automatically classified as, and remains
within, class III and requires premarket approval unless and until FDA
takes an action to classify or reclassify the device (see 21 U.S.C.
360c(f)(1)). We refer to these devices as ``postamendments devices''
because they were not in commercial distribution prior to the date of
enactment of the Medical Device Amendments of 1976, which amended the
Federal Food, Drug, and Cosmetic Act (FD&C Act).
FDA may take a variety of actions in appropriate circumstances to
classify or reclassify a device into class I or II. We may issue an
order finding a new device to be substantially equivalent under section
513(i) of the FD&C Act (21 U.S.C. 360c(i)) to a predicate device that
does not require premarket approval. We determine whether a new device
is substantially equivalent to a predicate device by means of the
procedures for premarket notification under section 510(k) of the FD&C
Act (21 U.S.C. 360(k)) and part 807 (21 CFR part 807).
FDA may also classify a device through ``De Novo'' classification,
a common name for the process authorized under section 513(f)(2) of the
FD&C Act. Section 207 of the Food and Drug Administration Modernization
Act of 1997 (Pub. L. 105-115) established the first procedure for De
Novo classification. Section 607 of the Food and Drug Administration
Safety and Innovation Act (Pub. L. 112-144) modified the De Novo
application process by adding a second procedure. A device sponsor may
utilize either procedure for De Novo classification.
Under the first procedure, the person submits a 510(k) for a device
that has not previously been classified. After receiving an order from
FDA classifying the device into class III under section 513(f)(1) of
the FD&C Act, the person then requests a classification under section
513(f)(2).
Under the second procedure, rather than first submitting a 510(k)
and then a request for classification, if the person determines that
there is no legally marketed device upon which to base a determination
of substantial equivalence, that person requests a classification under
section 513(f)(2) of the FD&C Act.
Under either procedure for De Novo classification, FDA is required
to classify the device by written order within 120 days. The
classification will be according to the criteria under section
513(a)(1) of the FD&C Act. Although the device was automatically placed
within class III, the De Novo classification is considered to be the
initial classification of the device.
When FDA classifies a device into class I or II via the De Novo
process, the device can serve as a predicate for future devices of that
type, including for 510(k)s (see section 513(f)(2)(B)(i) of the FD&C
Act). As a result, other device sponsors do not have to submit a De
Novo request or premarket approval application to market a
substantially equivalent device (see section 513(i) of the FD&C Act,
defining ``substantial equivalence''). Instead, sponsors can use the
less-burdensome 510(k) process, when necessary, to market their device.
II. De Novo Classification
On December 13, 2018, FDA received Woven Orthopedic Technologies,
LLC's request for De Novo classification of the OGmend[supreg] Implant
System. FDA reviewed the request in order to classify the device under
the criteria for classification set forth in section 513(a)(1) of the
FD&C Act.
We classify devices into class II if general controls by themselves
are insufficient to provide reasonable assurance of safety and
effectiveness, but there is sufficient information to establish special
controls that, in combination with the general controls, provide
reasonable assurance of the safety and effectiveness of the device for
its intended use (see 21 U.S.C. 360c(a)(1)(B)). After review of the
information submitted in the request, we determined that the device can
be classified into class II with the establishment of special controls.
FDA has determined that these special controls, in addition to the
general controls, will provide reasonable assurance of the safety and
effectiveness of the device.
Therefore, on May 1, 2020, FDA issued an order to the requester
classifying the device into class II. In this final order, FDA is
codifying the classification of the device by adding 21 CFR
888.3043.\1\ We have named the generic type of device ``screw sleeve
bone fixation device,'' and it is intended to be implanted in
conjunction with a non-resorbable, metallic bone screw where the screw
has lost purchase due to loosening, backout, or breakage. The device
fits between the screw threads and surrounding bone and provides
increased surface area to create an
[[Page 11294]]
interference fit to restore stability of the implant construct.
---------------------------------------------------------------------------
\1\ FDA notes that the ``ACTION'' caption for this final order
is styled as ``Final amendment; final order,'' rather than ``Final
order.'' Beginning in December 2019, this editorial change was made
to indicate that the document ``amends'' the Code of Federal
Regulations. The change was made in accordance with the Office of
Federal Register's (OFR) interpretations of the Federal Register Act
(44 U.S.C. chapter 15), its implementing regulations (1 CFR 5.9 and
parts 21 and 22), and the Document Drafting Handbook.
---------------------------------------------------------------------------
FDA has identified the following risks to health associated
specifically with this type of device and the measures required to
mitigate these risks in table 1.
Table 1--Screw Sleeve Bone Fixation Device Risks and Mitigation Measures
------------------------------------------------------------------------
Identified risks Mitigation measures

------------------------------------------------------------------------
FDA has determined that special controls, in combination with the
general controls, address these risks to health and provide reasonable
assurance of safety and effectiveness. For a device to fall within this
classification, and thus avoid automatic classification in class III,
it would have to comply with the special controls named in this final
order. The necessary special controls appear in the regulation codified
by this order. We encourage sponsors to consult with us if they wish to
use a non-animal testing method that they believe is suitable,
adequate, validated, and feasible. We will consider if such an
alternative method could be assessed for equivalency to an animal test
method. This device is subject to premarket notification requirements
under section 510(k) of the FD&C Act.
III. Analysis of Environmental Impact
The Agency has determined under 21 CFR 25.34(b) that this action is
of a type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
IV. Paperwork Reduction Act of 1995
This final order establishes special controls that refer to
previously approved collections of information found in other FDA
regulations and guidance. 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. 3501-3521). The collections
of information in 21 CFR part 860, subpart D, regarding De Novo
classification have been approved under OMB control number 0910-0844;
the collections of information in 21 CFR part 814, subparts A through
E, regarding premarket approval, have been approved under OMB control
number 0910-0231; the collections of information in part 807, subpart
E, regarding premarket notification submissions, have been approved
under OMB control number 0910-0120; the collections of information in
21 CFR part 820, regarding quality system regulation, have been
approved under OMB control number 0910-0073; and the collections of
information in 21 CFR part 801, regarding labeling, have been approved
under OMB control number 0910-0485.
List of Subjects in 21 CFR Part 888
