Intended Use
The StealthStation FlexENT™ System, with the StealthStation™ ENT Software, is intended as an aid for precisely locating anatomical structures in either open or percutaneous ENT procedures. Their use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as the skull, can be identified relative to images of the anatomy. This can include, but is not limited to, the following procedures: - Functional Endoscopic Sinus Surgery (FESS) - Endoscopic Skull Base procedures - Lateral Skull Base procedures The Medtronic SteathStation FlexENT™ computer-assisted surgery system and its associated applications are intended as an aid for precisely locating anatomical structures in either open or percutaneous ENT procedures. Their use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as the skull, can be identified relative to images of the anatomy.
Device 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. 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.

There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies. The functionality described is based on traditional image processing and tracking techniques.

No
The device is an aid for precisely locating anatomical structures during ENT procedures, providing guidance for the surgeon but not directly treating a medical condition itself.

No

The device is described as a surgical guidance platform intended to aid in precisely locating anatomical structures during ENT procedures. While it uses images and provides positional information, its primary function is not to diagnose medical conditions but to guide surgeons during interventions.

No

The device description explicitly states that 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). This indicates it is a system with both hardware and software components, not software-only. Furthermore, the performance studies include "Hardware Verification testing".

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 (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The StealthStation FlexENT™ System is an Image Guided System (IGS) used during surgical procedures to help surgeons precisely locate anatomical structures based on pre-operative or intra-operative images. It tracks the position of instruments relative to the patient's anatomy.
  • Intended Use: The intended use clearly states it's an "aid for precisely locating anatomical structures in either open or percutaneous ENT procedures." It does not involve the analysis of specimens taken from the body.

The device is a surgical navigation system, which falls under a different regulatory category than IVDs.

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.
