The pre-bent titanium plates are available in a small (L=31mm W=34mm, H=12mm) and a large size (L=35mm, W=36mm, H=16mm) along with left and right configurations. The plates can be trimmed along cutting lines and contoured to fit the specific needs of the patient. The plates are designed based on an average anatomical model of CT-scan data taken from 300 subjects (92% Caucasian). The metadata of the 300 subjects that have been included in the generation of the average anatomical model is listed in Table 1. The selected scans were obtained from healthy subjects without any deformation of the bony orbital structures. The globe retractor is an instrument designed to allow retraction of the orbital contents off the orbital floor and walls during implantation of the above mentioned pre-bent titanium plates. Lastly, the plate holding forceps is an instrument designed specifically for use with above mentioned pre-bent titanium plates. They facilitate the insertion and positioning of the plate within the orbit.
More Information

No
The device description focuses on pre-bent titanium plates designed based on average anatomical data, and does not mention any AI or ML algorithms for image processing, diagnosis, or treatment planning. The use of CT data was for the initial design of the plates, not for real-time or adaptive processing.

Yes
The device is intended for the reconstructive treatment of orbital floor and/or medial wall trauma or bone excision, which aligns with the definition of a therapeutic device as it directly treats a medical condition.

No
The device is described as a system for the reconstruction of the orbital floor and/or medial wall, including pre-bent titanium plates and instruments for implantation. Its intended use is for "reconstructive treatment" which indicates a therapeutic rather than diagnostic purpose.

No

The device description explicitly lists physical components: pre-bent titanium orbital floor plates, a globe retractor, and a plate holding forceps. These are hardware components, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Stryker Universal Orbital Floor System is a surgical implant and associated instruments used for the physical reconstruction of the orbital floor and/or medial wall. It is a physical device used in the body during surgery, not a device that analyzes samples from the body.
  • Intended Use: The intended use clearly states "reconstruction of the floor and/or medial wall of the orbit," which is a surgical procedure.
  • Device Description: The description details titanium plates, a globe retractor, and plate holding forceps – all surgical tools and implants.

Therefore, the Stryker Universal Orbital Floor System falls under the category of a surgical device or implant, not an In Vitro Diagnostic device.

510/k) Summarv

Introduction:

This Traditional 510(k) is being submitted to the FDA to grant clearance to market the Stryker Universal Orbital Floor System cleared via K123786 with the following modification.

Proposed Modification:

The Stryker Universal Orbital Floor System was cleared via K123786 for reconstruction of the floor and/or medial wall of the orbit in adult patients. This Traditional 510(k) is being submitted for the same system to expand the currently cleared Indications for Use to allow use of the device in patients 15 years of age and older. The rationale for limiting the indications to those patients 15 years of age and older is that the orbital volume has reached its adult size at that age. Except for this proposed change in indications, the device remains unchanged from its earlier cleared version.

Comparison with the Predicate Device:

The Stryker Universal Orbital Floor System is compared to its predicate device for substantial equivalence based on the following criteria:

  • A. Intended Use
  • B. Principle of Operation
  • C. Technological Characteristics
  • D. Benefit-Risk Evaluation

A: Intended Use/Indications for Use

Table 2: Substantial Equivalence of Indications for Use

Subject DevicePredicate Device
Intended UseIntended Use:

older.The Stryker Universal Orbital
Floor System is indicated for
the reconstructive treatment of
orbital floor and/or medial wall
trauma or bone excision in
adult patients.

The Indications for Use statement for the Stryker Universal Orbital Floor system is not identical to the predicate device; however, the differences do not alter the therapeutic use of the device nor do they affect the safety and effectiveness of the device relative to the predicate. Available evidence from the literature demonstrates that the subpopulation of patients age 15 to 21 is anatomically and physiologically identical to the population greater than 22 years of age. Both the Subiect and Predicate Device have the same intended use for reconstruction of the floor and/or medial wall of the orbit.

B. Principle of Operation

The basic operational principle of the Subject Device, as well as the Predicate Device, is to reconstruct the orbital floor and/or medial wall. The fixation method of both the Subject Device and the Predicate is with screws inserted through

7

dedicated screw holes. The Subject Device and the Predicate Device are both permanent implants and have the same craniomaxillofacial (CMF)/orbital area of application.

C. Technological Characteristics

There is no design change; the Stryker Universal Orbital Floor System has the exact same design as the Predicate Device:

  • -Same patient contacting surface: orbital floor and wall
  • -Same area of contact and contact duration (tissue/bone/permanent implant)
  • -Same material: titanium
  • -Same design: pre-bent shape based on average anatomical model
  • -Same sizes and shapes as the Predicate Device
  • -Same mode of plate adjustment: trimming along cutting lines and bending
  • -Both the Subject Device and Predicate Device are provided non-sterile

D. Benefit-Risk Evaluation

The design of the device approximates the shape and dimensions of the average normal orbital floor and medial wall in order to facilitate the operative goal of restoring normal (pre-traumatic) orbital volume as accurately as possible. Additionally, this approximation simplifies the bending and fitting process for the surgeon during an orbital procedure, while still allowing the surgeon to trim and contour the material to fit the specific needs of the patient. A review of the literature shows that titanium mesh and other alloplastic implants have been used for orbital repair in a pediatric subpopulation of 15 to 21 years of age for over 25 years. In published studies on the use of permanent fixation in the craniomaxillofacial skeleton in a pediatric subpopulation of 15 to 21 years of age, only the detrimental effects on growth have been noted, with no other reported complications due to age. Complications associated with the use of alloplastic material in the pediatric population were no different than the risks identified for the Subject Device, which include infection, migration, and foreign body reaction.2 The complication rate in this age group is not shown to be greater than that seen in the 22 and over population. 3 Based on the risk assessment and data reported in the clinical literature, any adverse events are minimized and acceptable when weighed against the benefits of the intended performance.

Substantial Equivalence Analysis:

The conclusions drawn from the comparison of the intended use, principle of operation, and technological characteristics, including the clinical performance data from the literature and benefit-risk evaluation, demonstrate that the Stryker Universal Orbital Floor System performs substantially equivalent to the Predicate Device. The differences in Indications for Use do not raise new questions of safety and effectiveness.

8

Clinical Testing:

There was no clinical performance testing required because the differences in Indications for Use do not raise new questions of safety and effectiveness. The clinical performance data provided in the literature on analogous reference devices supports an indication in patients 15 years of age and older.

Non-Clinical Testing:

The proposed modification does not have any impact on the performance of the device. Hence, no additional non-clinical testing has been performed. Previously conducted performance tests as described in K123786 included Verification and Validation (V&V) testing of biocompatibility, cleaning, sterilization, corrosion resistance, stability of plate, functionality over lifetime, transportation of the complete set and of packaging, an end product test and a design validation - end user test. The Stryker Universal Orbital Floor System passed all tests.

Conclusions:

The results of the non-clinical data demonstrate the Stryker Universal Orbital Floor System will perform as intended in the specified use conditions. The intended use, technological characteristics, clinical performance data presented in the literature, and the benefit-risk evaluation supports that known and foreseeable risks, and any adverse events, are minimized and acceptable when weighed against the benefits of the intended performance of the device during normal conditions of use executed per the product labeling. According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence.
