icotec Navigation Instruments are intended to be used during the preparation and placement of FDA-cleared icotec pedicle screws during spinal surgery to assist the surgeon in precisely locating anatomical structures. These instruments are designed for use with stereotactic navigation system Medtronic StealthStation®, which 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 a vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks of the anatomy.

The purpose of this Traditional 510(k) is to seek marketing clearance for the VADER® Pedicle System Navigated Instruments.

icotec's VADER® Pedicle System Navigated Instruments are reusable instruments used for the preparation and placement of FDA-cleared icotec pedicle screws during spinal surgery to assist the surgeon in precisely locating anatomical structures. These instruments are designed for use with navigation system Medtronic StealthStation® in combination with the Medtronic NavLock™ tracker and Medtronic SureTrak®II clamps and arrays.

The VADER® Pedicle System Navigated Instruments include awls, probes, taps, drivers and adapters. The VADER® Pedicle System Navigated Instruments are to be used with the FDAcleared icotec pedicle screws cleared under K222789. K200596. K193423 and K190545.

This document is a 510(k) Premarket Notification from the FDA regarding the VADER® Pedicle System Navigated Instruments. It confirms that the device is substantially equivalent to a predicate device and can be marketed.

However, the provided text does not contain the detailed information requested regarding acceptance criteria and the specifics of the study proving the device meets those criteria.

Here's what can be extracted and what is missing:

1. Table of acceptance criteria and reported device performance:

• Missing: The document only generally states that "Performance Testing" was conducted to "verify that the VADER® Pedicle System Navigated Instruments are appropriate for their intended use, to ensure functionality, accuracy and compatibility with the Medtronic StealthStation® System using the NavLock™ tracker and SureTrak®II clamps and arrays, and to demonstrate substantial equivalence to the predicate instruments." It does not provide specific quantitative acceptance criteria (e.g., accuracy thresholds, precision values) or their corresponding reported performance values.

2. Sample size used for the test set and the data provenance:

• Missing: The document mentions "anatomical and navigated simulated use and accuracy and reliability testing" but does not specify the sample size of the test set (e.g., number of simulated procedures, number of anatomical models, number of measurements). It also does not provide data provenance (e.g., country of origin, retrospective or prospective).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Missing: This information is not provided.

4. Adjudication method for the test set:

• Missing: This information is not provided.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size:

• Missing: The document does not describe an MRMC comparative effectiveness study where human readers improve with or without AI assistance. The device is a set of navigated instruments, not an AI diagnostic tool that assists human readers in interpreting data.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• Not applicable/Missing: The device is a set of navigated instruments for use during surgery with a navigation system (Medtronic StealthStation®), which inherently involves a human surgeon. It's not an algorithm that performs actions "standalone" without human interaction. The performance testing likely evaluated the accuracy and reliability of the instruments in conjunction with the navigation system and human use, not as a standalone algorithm.

7. The type of ground truth used:

• Missing: The document describes "anatomical and navigated simulated use" but does not explicitly state how ground truth was established for these tests (e.g., a "true" anatomical position determined by a gold standard method before navigation, or a reference measurement).

8. The sample size for the training set:

• Not applicable/Missing: The document describes a medical device (navigated instruments), not a software or AI model that typically has a training set. Therefore, there is no "training set" in the context of this device.

9. How the ground truth for the training set was established:

• Not applicable/Missing: Similar to point 8, there is no training set for this type of device.

Summary of what is provided:

• Device Name: VADER® Pedicle System Navigated Instruments
• Intended Use: To be used during the preparation and placement of FDA-cleared icotec pedicle screws during spinal surgery to assist the surgeon in precisely locating anatomical structures. Designed for use with stereotactic navigation system Medtronic StealthStation®.
• Performance Testing Mentioned: "one-to-one dimensional comparison to demonstrate substantially equivalent geometry that is critical to navigation accuracy. Testing, including anatomical and navigated simulated use and accuracy and reliability testing, has been conducted to verify that the VADER® Pedicle System Navigated Instruments are appropriate for their intended use, to ensure functionality, accuracy and compatibility with the Medtronic StealthStation® System using the NavLock™ tracker and SureTrak®II clamps and arrays, and to demonstrate substantial equivalence to the predicate instruments."
• Conclusion: The device was demonstrated to be substantially equivalent to the predicate device (VERTICALE® Navigation Instruments, K223649) with respect to indications, design, and performance, based on the performance testing.
