Indications for Use

The InstaTrak 3000 System is intended as an aid to the surgeon for precisely locating anatomical structures anywhere on the human body during either open or percutaneous procedures. It is indicated for any medical condition that may benefit from the use of stereotactic surgery and which provides a reference to rigid anatomical structures such as sinus, skull, cranial, long bone, or vertebra, visible on medical images such as CT, MR, or X-ray.

Device Story

InstaTrak 3000 with FluoroTrak is an intraoperative image-guided surgical system. It uses electromagnetic tracking technology to determine the real-time position of surgical instruments relative to a patient's anatomy. Inputs include pre-operative medical images (CT, MR, or X-ray) and real-time electromagnetic sensor data from tracked instruments. The system registers the patient to the image data, allowing the surgeon to visualize the instrument's location on a monitor. Used in OR settings by surgeons to navigate complex anatomy, avoid critical structures, and guide surgical tools. The FluoroTrak module adds a calibration fixture to support X-ray image integration. Output is a visual display of instrument position overlaid on patient images, assisting in surgical precision and potentially improving patient outcomes by reducing risk to surrounding tissues.

Clinical Evidence

Bench testing only. Testing was performed on the new calibration fixture component to verify that it did not adversely affect the accuracy of the InstaTrak 3000 system. Results demonstrated that the device performed within established specifications.

Technological Characteristics

Electromagnetic position sensing; computer-based workstation with monitor and hard disk storage; calibration fixture for X-ray integration; supports CT, MR, and X-ray image modalities; software-based registration process.

Indications for Use

Indicated for patients undergoing open or percutaneous stereotactic surgical procedures requiring navigation of rigid anatomical structures (sinus, skull, cranial, long bone, vertebra) visible on CT, MR, or X-ray images.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

Predicate Devices

• InstaTrak 3000 System (K983529)
• StealthStation System with FluoroNav Module (K990214)

#### 4. Device Description

The InstaTrak 3000 System is an image guidance system indicated for use during sinus, skull base, cranial and axial skeletal procedures. The InstaTrak

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

3000 with FluoroTrak is similar to the InstaTrak 3000 System cleared under K983529. The changes to the system include software enhancements and the addition of a calibration fixture. Using the InstaTrak 3000, the surgeon can readily identify the immediate location and position of the surgical instrument during the indicated procedure. The InstaTrak 3000 assists the surgeon in avoiding critical nerves and other anatomical structures.

The InstaTrak 3000 offers multiple modes of operation that includes sinus, skull base, cranial, axial skeletal, to the user based on the indications the user desires. Software is available to the user for using any one, two, or all three of the operational modes. A selection of the operational modes is made by the user prior to the procedure depending needs of the user.

The original InstaTrak 3000 System allows the user to view the reconstructed 2D images of the patient's anatomy in response to the mouse or the tracked surgical instrument. Alignment of the patient and images is accomplished through the registration process. In all types of surgery the goal is the same, to indicate to the surgeon based on the pre-operative medical images, where the position of a tracked surgical tool is with regard to the patient's anatomy. The InstaTrak 3000 with FluoroTrak is based on the same hardware and software used in the original InstaTrak System and provides all of the above features. It utilizes the same clinically proven electromagnetic tracking technology as its predecessor.

# 5. Intended Use

The InstaTrak 3000 System is intended as an aid to the surgeon for precisely locating anatomical structures anywhere on the human body during either open or percutaneous procedures. It is indicated for any medical condition that may benefit from the use of stereotactic surgery and which provides a reference to rigid anatomical structures such as sinus, skull, cranial, long bone, or vertebra, visible on medical images such as CT, MR, or X-ray.

# 6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE

The InstaTrak 3000 with FluoroTrak, the original InstaTrak 3000 and the Stealth Station with FluoroNav are similar in intended use as they are all indicated for locating rigid anatomical structures during either open or percutaneous procedures. The InstaTrak 3000 with FluoroTrak is identical to both the original InstaTrak 3000 System and the Stealth Station with FluoroNav devices in that they are all intraoperative image-guidance systems intended for cranial, skull base, axial skeletal and sinus surgery.

{2}------------------------------------------------

The InstaTrak 3000 with FluoroTrak is essentially identical in technological characteristics to the InstaTrak 3000 System cleared under K983529 with the exception of software enhancements and the addition of the calibration fixture. The InstaTrak 3000 with FluoroTrak uses the same electromagnetic position sensing, and registration process as the original InstaTrak 3000 System cleared under K983529.

The InstaTrak 3000 with FluoroTrak, the original InstaTrak 3000 System and the Stealth Station with FluoroNav all use a computer, monitor and hard disk storage system. Both the FluoroTrak and FluoroNav systems offer image guidance using CT, MR or X-Ray images while the original InstaTrak 3000 System only offers CT and MR images.

There is only one new component associated with the InstaTrak 3000 with FluoroTrak, which is the addition of the calibration fixture. This new component will be used with the InstaTrak 3000 System and has been added to accommodate the FluoroTrak Module .

There are no new instruments used other than what was described in the original 510(k) (K983529) for the InstaTrak 3000 System.

## 7. PERFORMANCE TESTING

Testing was performed using the new component of the InstaTrak 3000 with FluoroTrak to determine if the new component affected device accuracy. The results showed that the device performed within the specification while using the new component.
