#### Marketed Devices:
OEC Elite is a Mobile Fluoroscopic C-arm Imaging System built upon the existing technologies of the predicate device OEC 9900 Elite (K122234) and reference devices. It is of comparable type and substantially equivalent to its predicate device OEC 9900 Elite. The new flat panel detector for the OEC Elite provides similar imaging performance to those used in the two reference devices. Ziehm Vision FD and Ziehm Solo FD Digital Mobile C-arm. The intended use has not changed between the proposed device and the predicate device. The proposed device's indications for use have been revised to clearly identify current and historical patient populations and the system capabilities as substantiated in the testing and evaluations provided.
The system is labeled as the OEC Elite.
# Device Description:
The OEC Elite is a Mobile Fluoroscopic C-arm Imaging system used to assist trained surgeons and other qualified physicians. The system is used to provide fluoroscopic X-Ray images during diagnostic, interventional, and surgical procedures. These images help the physician visualize the patient's anatomy and interventional tools. This visualization helps to localize clinical regions of interest and pathology. The images provide real-time visualization and records of pre-procedure anatomy, in vivo-clinical activity and post-procedure outcomes. The system is composed of two primary physical components. The first is
{5}------------------------------------------------
referred to as the "C - Arm" because of its "C" shaped image gantry; the second is referred to as the "Workstation", which is the primary interface for the user to interact with the system.
The C-arm is a stable mobile platform capable of performing linear motions (vertical, horizontal) and rotational motions (orbital, lateral, wig-wag) that allow the user to position the X-Ray image chain at various angles and distances with respect to the patient anatomy to be imaged. The C - arm is mechanically balanced allowing for ease of movement and capable of being "locked" in place using a manually activated lock. The C-Arm is comprised of the high voltage generator, software, X-ray control, and a "C" shaped image gantry, which supports an X-ray tube and a Flat Panel Detector or Image Intensifier, depending on the choice of detector configuration desired.
The workstation is a stable mobile platform with an articulating arm supporting a color image, high resolution, LCD display monitor. It also includes image processing equipment/software, recording devices, data input/output devices and power control systems.
The primary purpose of the mobile fluoroscopy system is to provide fluoroscopic images of the patient during diagnostic, interventional, and surgical procedures such as orthopedic, gastrointestinal, endoscopic, urologic, neurologic, critical care and emergency procedures.
The OEC Elite comes with four image receptor (detector) options: the choice of 21x21 cm or 31x31 cm (new) Thallium-doped Cesium Iodide [Cs](Tl)] solid state flat panel X-ray detector with Complementary Metal Oxide Semiconductor (CMOS) light imager; or the choice of a 9 inch or 12 inch of the same existing image intensifier as in the OEC 9900 Elite.
The most outwardly visible technology change for this new device compared to the predicate, OEC 9900 Elite, is the introduction of the new Cs1:T1 - CMOS detectors. However, the new flat panel detectors for the OEC Elite are substantially equivalent to those of the two reference devices.
Additionally, software and hardware design modifications have been made to the subject device, OEC Elite, which are intended to improve the overall performance and reliability of the system and to eliminate or reduce failure mechanisms that periodically occurred with the predicate device, specifically: loss of cine functionality, data loss/mix, system lockup, no live image, failure to boot, and uncommanded X-ray. These modifications include a redesigned computer architecture (hardware and software), elimination and redesign of interconnecting cables, and addition of continuous monitoring of power conditions and new Uninterrupted Power Supply (UPS), and new on-screen user messaging (e.g., battery life and charge indications).
# Intended Use
The OEC Elite Mobile C-arm is intended to provide fluoroscopic and digital spot images of the patient anatomy, interventional tools/devices, and contrast agents during diagnostic, interventional, and surgical procedures.

The OEC Elite mobile fluoroscopy system is designed to provide fluoroscopic and digital spot images of adult and pediatric populations during diagnostic, interventional and surgical procedures. Examples of a clinical application may include: orthopedic, gastrointestinal, endoscopic, urologic, critical care and emergency procedures.
#### Technology:
The OEC Elite employs the same fundamental scientific technology as that of the predicate device OEC 9900 Elite (K122234) and the reference devices, Ziehm Vision FD Digital Mobile Imaging System (K132904) and Ziehm Solo FD (K161976).
OEC Elite introduces Thallium-doped Cesium Iodide [Cs](Tl)] solid state flat panel X- ray detectors with Complementary Metal Oxide Semiconductor (CMOS) photodiodes. However, the new flat panel detector for the OEC Elite provides similar imaging performance to those used in the two reference devices.
The X-Ray source and generator remain unchanged from that of the OEC 9900 Elite. On the workstation, the main hardware changes include an updated computer that offers more image storage, processing power and speed, and a single monitor. The workstation mechanical design is improved for usability, maneuverability, and positioning.
The changes described above do not change the control mechanism, operating principle, energy type, or intended use from the predicate and reference devices.
# Determination of Substantial Equivalence:
The main change in the proposed device is the introduction of the Thallium-doped Cesium Iodide [Csl(TI)] solid state flat panel X- ray detector with Complementary Metal Oxide Semiconductor (CMOS) photodiodes.

GE Healthcare believes the OEC Elite is of comparable type and substantially equivalent to our currently marketed system OEC 9900 Elite.
The substantial equivalence was also based on software documentation for a "Moderate" level of concern device.
# Summary of Additional Testing
In addition to the verification and validation testing successfully completed as required by GE OEC Medical System's Quality Management System, additional engineering (non-Clinical) testing was performed to provide the requisite data to substantiate performance claims, the revised indications, and ultimately substantial equivalence.
#### Non-Clinical Testing
Verification and validation, including hazard mitigation has been executed with results demonstrating the OEC Elite mobile fluoroscopy system met design input and user needs.
The system has been tested and is compliant with the IEC 60601-1 Ed. 3 series, including IEC60601-2-54 and IEC 60601-2-43. All applicable 21CFR Subchapter J performance standards are met. The OEC Elite system was developed under the GE OEC Medical Systems Quality Management System, including design controls, risk management and software development life cycle processes. The following quality assurance measures were applied to the development of the system:
- · Risk Analysis
- Required Reviews
- Design Reviews
- · Testing on unit level (Sub System verification)
- · Integration testing (System verification)
- · Performance testing (Verification)
- · Safety testing (Verification)
- · Simulated use testing (Validation)
Additional engineering bench testing was performed including: the non-clinical testing identified in the guidance for submission of 510(k)s for Solid State X-Ray Imaging Devices (SSXI); demonstration of system performance; and an imaging performance evaluation using anthropomorphic phantoms. All the image quality/performance testing identified for fluoroscopy found in FDA's "Information for Industry:

There are four white water droplet shapes surrounding the circle, positioned at the top, bottom, left, and right. The logo is simple and recognizable, representing the company's brand identity.
X-ray Imaging Devices- Laboratory Image Quality and Dose Assessment, Tests and Standards' was performed with acceptable results.
With regards to the flat panel detector (SSXI), test documentation provided in this submission demonstrates compliance of the OE Elite to "Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging Devices". The evaluation includes but is not limited to the following performance metrics identified in the SSXI guidance, showing comparable or better performance of the OEC Elite compared to the predicate device OEC 9900 Elite:
| SSXI Metrics | OEC Elite Performance Compared to |
|---------------------------------------------------|-----------------------------------|
| | Predicate OEC 9900 Elite |
| DQE | Improved |
| Dynamic Range | Improved |
| Spatial Resolution (MTF, Limiting Resolution) | Equivalent |
| Temporal Resolution | Equivalent |
| Contrast Resolution | Equivalent |
| Beam Alignment | Equivalent |
| Dose Rate | Equivalent |
| Stability of the device characteristics over time | Equivalent |
| brightness uniformity | Improved |
| Fluoroscopy Frame Rate | Equivalent |
| Reuse Rate | Equivalent |
# Clinical Testing
Because OEC Elite's new flat panel detectors do not change the system's intended use and represent equivalent technological characteristics, clinical images are not required. Also, because the II configurations are identical to the predicate, clinical images are not included for them. Therefore, for all OEC Elite configurations, clinical images are not needed to demonstrate that the device is as safe and as effective as the predicate and reference devices.
#### Substantial Equivalence Conclusion:
The differences discussed in this section do not introduce any adverse effects nor raise new questions of safety and effectiveness. Based on the successful verification and validation testing, additional engineering bench testing, conformance to standards, and development under GE OEC Medical System's Quality Management System, we believe that the OEC Elite is of comparable type and substantially equivalent to the predicate device OEC 9900 Elite (K122234) with support from the reference devices, and therefore is safe and effective for its intended use.
