Dear Mr. Rogers:
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.

#### IV. DEVICE DESCRIPTION
The BE-ST Navigated PAK Needles are single use surgical instruments composed of stainless steel and plastic. They are sterile packaged. The devices are comprised of three main components: the cannula, stylet assembly, and tracker subassembly.
There are two devices in the family: the BE-ST Navigated NIM® PAK Needle and the BE-ST Navigated PAK Needle. The BE-ST Navigated NIM® PAK Needle is an accessory to the Medtronic StealthStation® System and is intended for use as a stimulating accessory to the Medtronic NIM® System. The BE-ST Navigated PAK Needle is an accessory to the Medtronic StealthStation® System.
{4}------------------------------------------------
The only significant differences between the two subject devices are the electrical insulation on the cannula and the connection to the NIM® System. The BE-ST Navigated PAK device has the same basic function and navigational capabilities as the BE-ST Navigated NIM® PAK device but is not an accessory to the Medtronic NIM® system and therefore cannot be used for nerve monitoring.
The Medtronic StealthStation® System and Medtronic NIM® System are not included in the scope of this premarket notification.
# V. INDICATIONS FOR USE
The BE-ST NAV PAK is indicated for navigated pedicle pilot hole preparation. The BE-ST NAV PAK should only be used with a compatible Medtronic StealthStation® System.
The BE-ST NAV NIM® PAK is indicated for navigated pedicle pilot hole preparation, locating, and identifying nerves during surgery, including spinal nerve roots. The BE-ST NAV NIM® PAK should only be used with compatible Medtronic StealthStation® and Medtronic NIM® Systems.
## VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The BE-ST Navigated NIM® PAK device is based on the predicate Medtronic Navigated NIM-SPINE® PAK Needle. The BE-ST Navigated NIM® PAK device is similar to the BE-ST NIM® PAK device with the addition of a tracker assembly which allows the device to be used with the Medtronic StealthStation® System. The subject device and the BE-ST NIM® PAK device have the same technological features, the same basic geometry, and are manufactured from the same materials, with the exception that the subject device has a tracker assembly which is substantially equivalent to the tracker assembly on the Medtronic predicate device.
The BE-ST Navigated PAK device has the same basic function and navigational capabilities as the BE-ST Navigated NIM® PAK device but does not have neural integrity monitoring capabilities.
