#### VII. Product Description
The StealthStation FlexENT™ is an electromagnetic based surgical guidance platform that supports use of special application software (StealthStation™ S8 ENT Software 1.3 and associated instruments.
The StealthStation™ S8 ENT Software 1.3 helps guide surgeons during ENT procedures such as functional endoscopic sinus surgery (FESS), endoscopic skull base procedures, and lateral skull base procedures. StealthStation™ S8 ENT Software 1.3 functionality is described in terms of its feature sets which are categorized as imaging modalities, registration, planning, and views. Feature sets include functionality that contributes to clinical decision making and are necessary to achieve system performance.
{5}------------------------------------------------
Patient images can be displayed by the StealthStation™ S8 ENT Software 1.3 from a variety of perspectives (axial, sagittal, coronal, oblique) and 3dimensional (3D) renderings of anatomical structures can also be displayed. During navigation, the system identifies the tip location and traiectory of the tracked instrument on images and models the user has selected to display. The surgeon may also create and store one or more surgical plan trajectories before surgery and simulate progression along these trajectories. During surgery, the software can display how the actual instrument tip position and trajectory relate to the plan, helping to guide the surgeon along the planned trajectory. While the surgeon's judgment remains the ultimate authority, realtime positional information obtained through the StealthStation™ System can serve to validate this judgment as well as guide. The StealthStation™ S8 ENT v1.3 Software can be run on both the StealthStation FlexENT™ and StealthStation™ S8 Platforms.
The StealthStation™ System is an Image Guided System (IGS), comprised of a platform (StealthStation FlexENT™ or StealthStation™ S8), clinical software, surgical instruments, and a referencing system (which includes patient and instrument trackers). The IGS tracks the position of instruments in relation to the surgical anatomy, known as localization, and then identifies this position on preoperative or intraoperative images of a patient.

#### XI. Discussion of the Performance Testing
Testing conducted demonstrates the product will perform as intended according to the outlined design requirements. The following testing was conducted on the StealthStation FlexENT™ Platform to establish substantial equivalence of the system and verify that the device will perform as intended meeting all the design inputs. The subject devices met all the performance testing requirements:
- . Electrical Emissions and Immunity 4th edition testing provided confirmation that the StealthStation FlexENT™ platform conforms to AAMI/ANSI ES 60601-1:2012 - Medical Electrical Equipment - Part 1: General Requirements for Basic Safety and Essential Performance (IEC 60601-1:2005, MOD).
- . Electrical, Mechanical, Thermal Safety testing confirmed that the StealthStation FlexENT™ platform conforms to IEC 60601-1-2:2014 -Medical Electrical Equipment - Part 1-2: General requirements for safety; Electromagnetic Compatibility - Requirements and Tests.
- ' Software Verification and Validation testing verified the operating system software requirements are met and software performs as intended
- l Hardware Verification testing ensuring the hardware requirements identified for the system are met and hardware performs as intended
- . The StealthStation FlexENT™ platform and product labeling was tested for the intended user profiles, uses, and use environments in accordance to FDA quidance "Applying Human Factors and Usability Engineering to Medical Devices" demonstrating that the usability and human factors requirements were adequately met. The StealthStation FlexENT has been found to be adequately safe and effective for the intended users, uses and use environments.
For the software, Integration tests are executed as part of development tasks for every code change. These tests are executed and must pass prior to merging into the production code branch for formal testing. Verification & validation tests are then executed, and evidence of final passing execution is documented in the Verification & Validation Plan-Summary
The following table summarizes the testing conducted on the StealthStation FlexENT™ and the StealthStation™ S8 platforms with StealthStation™ ENT v1.3 Software.
Description
{12}------------------------------------------------
Testing was performed under the representative worst-case configuration, for the StealthStation™ S8 ENT 1.3 Software running on the StealthStation FlexENT™ and the StealthStation™ S8 platforms. Results demonstrated performance in 3D positional accuracy with a mean error ≤ 2.0 mm and in trajectory angle accuracy with a mean error ≤ 2.0 degrees. This performance was determined using anatomically representative phantoms and utilizing a subset of system components and features that represent the worst-case combinations of all potential system components. The results show that the update to the StealthStation™ S8 ENT 1.3 Software running on the StealthStation FlexENT™ and the StealthStation™ S8 platforms do not impact overall system accuracy performance.
