Intended Use

The UNI KNEE SURGETICS Navigation System is intended for use during stereotaxic surgery to aid the surgeon in locating anatomical structures and aligning the endoprostheses with the anatomical structures. It is specifically indicated for : - UniKnee Arthroplasty .

Device Story

Image-guided surgical navigation system; inputs include optical tracking data from reflective markers attached to patient anatomy and surgical instruments; system processes spatial data via optical localizer and mobile computer station to provide real-time guidance; output displayed to surgeon for anatomical localization and endoprosthesis alignment; used in OR by surgeons; facilitates precise implant positioning; modular software architecture allows integration of new implants and adaptation to various surgical techniques.

Clinical Evidence

Bench testing and specimen testing only. Analyses demonstrated that system accuracy and performance were adequate for the intended use and equivalent to predicate devices.

Technological Characteristics

System comprises a mobile computer station (Surgetics Station or NanoStation), optical localizer, ancillary instruments, and reflective markers. Operates as an image-guided stereotaxic navigation system. Software architecture is modular to support various implants and surgical workflows.

Indications for Use

Indicated for patients undergoing UniKnee Arthroplasty surgery requiring stereotaxic navigation for anatomical structure localization and endoprosthesis alignment.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

Predicate Devices

• Surgetics ORTHO KNEELOGICS Navigation System (K031196)
• TOTAL KNEE SURGETICS Navigation System (K060282)

Contact Name: Mady BATAILH Telephone: [phone]

Date Prepared: July 17th, 2006

#### 2. Device Name:

Proprietary Name: UNI KNEE SURGETICS Navigation System Common/Usual Name: Image guided surgical navigation system Classification Name: Computed tomography x-ray system (accessory)

#### 3. Equivalent to:

K031196 - Surgetics ORTHO KNEELOGICS Navigation System K060282 - TOTAL KNEE SURGETICS Navigation System

#### 4. Intended Use:

The UNI KNEE SURGETICS Navigation System is intended for use during stereotaxic surgery to aid the surgeon in locating anatomical structures and aligning the endoprostheses with the anatomical structures.

It is specifically indicated for :

- UniKnee Arthroplasty .

{1}------------------------------------------------

#### న. Device Description:

As the equivalent Surgetics ORTHO KNEELOGICS Navigation System and TOTAL KNEE SURGETICS Navigation System, the UNI KNEE SURGETICS navigation System consists of the following major components and subsystems:

- The Surgetics Station or the NanoStation, consisting of a mobile computer . system and an optical localizer
- Ancillary instruments and reflective markers used for reference and . registration
- UNI KNEE SURGETICS software .

The main modifications to the predicate devices concern the internal architecture of the software, allowing more easily to integrate new implants and to better adapt the workflow to different surgical techniques. New instruments adapted to new implants are also incorporated.

#### Technological Characteristics and Substantial Equivalence 6.

The underlying technology of the UNI KNEE SURGETICS Navigation System is the same as for the predicate devices. The system is based on the same operating principle and control mechanism to provide the user with the same kind of information and guidance for the same surgery. The main changes with respect to the predicate device concern software and engineering modifications with regard to easy integration of new implants (modularization). In addition, the software was modified in order to allow easier adaptation of the workflow to the characteristics of each implant and to different surgical techniques. New navigated instruments have been developed also with respect to easier integration of new implants.

#### Performance Testing 7.

The UNI KNEE SURGETICS Navigation System was tested in a non clinical setting (bench testing, specimen) to assess that no new safety and efficiency issues were raised in the device. Analyses show that the accuracy and performance of the system was adequate for its intended use and not reduced in comparison to the predicate devices. In conclusion the UNI KNEE SURGETICS Navigation System is substantially equivalent to the Surgetics ORTHO KNEELOGICS Navigation System and the TOTAL KNEE SURGETICS Navigation System.
