CoreLink Navigation Instruments are intended to be used in the preparation and placement of CoreLink screws (Tiger and Entasis) during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. These instruments are designed for use with the Medtronic StealthStation® System S8 (V1.2.20), 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 vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks of the anatomy.
CoreLink Navigation Instruments are non-sterile, re-usable manual surgical instruments made from stainless steel. These instruments are designed to interface with the Medtronic StealthStation® Navigation System to assist surgeons in precisely locating anatomical structures.
The purpose of this submission is to clear the CoreLink Navigation Instruments for use with additional versions of the StealthStation software and to add instruments to the previously cleared CoreLink Navigation Instruments set.
This is a 510(k) premarket notification for CoreLink Navigation Instruments.
Here's a breakdown of the requested information based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The document mentions "confirmatory positional accuracy testing per ASTM F2554" but does not explicitly state the acceptance criteria (e.g., a specific tolerance in mm) or the numerical results of this performance testing. It only states that the testing was done to "demonstrate that the system modifications provide adequate and substantially equivalent accuracy for their intended use."
| Acceptance Criteria (Not Explicitly Stated in Document) | Reported Device Performance |
|---|---|
| Positional Accuracy per ASTM F2554 (Specific metric not provided) | Adequately and substantially equivalent accuracy for intended use (Specific numerical results not provided) |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the sample size used for the positional accuracy testing. It also does not explicitly state the data provenance (e.g., country of origin, retrospective or prospective).
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
This information is not provided in the document. The testing described focuses on device performance against a standard (ASTM F2554) rather than human expert-established ground truth.
4. Adjudication Method for the Test Set
This information is not provided in the document. Adjudication methods are typically relevant for studies involving human interpretation or subjective assessments, which isn't explicitly described here.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study is not mentioned. The document describes testing of the navigation instruments' accuracy, not a study comparing human reader performance with and without AI assistance.
6. If a Standalone Study (Algorithm Only Without Human-in-the-Loop Performance) Was Done
Yes, a standalone study of the device's performance was done. The document states that CoreLink, LLC "conducted confirmatory positional accuracy testing per ASTM F2554 with Medtronic StealthStation® System S8 Version 1.2.0 (1.2.0-20)." This refers to testing the device itself for accuracy, independent of a human surgeon's interaction in a clinical setting for the purpose of this particular performance data section.
7. The Type of Ground Truth Used
The ground truth for the positional accuracy testing would be established by the specifications and methodology of ASTM F2554, which defines how to measure and assess the accuracy of navigated surgical instruments. This standard typically involves objective measurements against a known reference or ideal position, rather than expert consensus, pathology, or outcomes data.
8. The Sample Size for the Training Set
This device is a set of manual surgical instruments that interface with a navigation system, not an AI or machine learning algorithm that requires a training set in the conventional sense. Therefore, the concept of a "training set" is not applicable here.
9. How the Ground Truth for the Training Set Was Established
As explained above, a training set is not applicable for this type of device.

Dear Nathan Wright:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
