Intended Use
The BE-ST NIM® PAK Needle, Blunt, and Pedicle Probe are indicated for pedicle pilot hole preparation, locating, and identifying cranial and peripheral motor nerves during surgery, including spinal nerve roots.
Device Description
The BE-ST NIM® PAK Needle, Blunt, and Pedicle Probe are single use devices composed of stainless steel and plastic and are sterile packaged. The devices are comprised of two main components: the cannula and stylet assembly. Also, in the package are two monopolar cables: a subdermal needle electrode and a connecting cable. The NIM® PAK devices are available in standard "NIM® PAK" or longer "NIM® XPAK" configurations with 3 different types of tips: bevel, trocar or blunt. The blunt tips are only offered for the NIM® XPAK. In addition, there are three (3) NIM Pedicle Probes in lumbar, straight, and thoracic configurations. The BE-ST NIM® product family has a total of four (4) pedicle access needle configurations, three (3) pedicle probe configurations, and one (1) blunt configuration. All configurations are packaged with two (2) accessory monopolar cables. One cable is used to ground the patient and the other cable is used to connect the device to a Medtronic Neural Integrity Monitor (NIM®). The connection to the NIM® allows the subject device to provide stimulation to nerves.

No
The device description and performance studies focus on the mechanical, electrical, and biological properties of the probes and needles, and their connection to a separate neural integrity monitor for stimulation. There is no mention of data processing, algorithms, or learning capabilities within the device itself.

Yes
The device is used to locate and identify motor nerves, including spinal nerve roots, during surgery. This function directly relates to the diagnosis or treatment of a condition by providing critical information to the surgeon to avoid nerve damage and ensure proper placement of implants (e.g., pedicle screws). It also provides stimulation to nerves, which can be considered a therapeutic or diagnostic function in the context of neural monitoring.

Yes

The device is indicated for "locating, and identifying cranial and peripheral motor nerves during surgery, including spinal nerve roots," which is a diagnostic function. It connects to a Neural Integrity Monitor (NIM®) which allows it to provide stimulation to nerves and assess their integrity.

No

The device description explicitly states the devices are composed of stainless steel and plastic, are single-use, sterile packaged, and include physical components like cannulas, stylets, and cables. The performance studies also detail testing on physical attributes like impact, mechanical strength, and biocompatibility.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for "pedicle pilot hole preparation, locating, and identifying cranial and peripheral motor nerves during surgery, including spinal nerve roots." This describes a surgical tool used in vivo (within the body) to interact with tissues and nerves.
  • Device Description: The description details a physical instrument (cannula, stylet, probes) used for mechanical manipulation and electrical stimulation in vivo.
  • Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) outside of the body to provide diagnostic information. IVDs are specifically designed for testing samples in vitro.

The device is a surgical instrument used for nerve monitoring and access during surgery, which falls under the category of medical devices, but not specifically In Vitro Diagnostics.

Summary of Performance Studies

Bench Testing:
Functional use and reliability testing was performed comparing the subject devices and predicate devices, including impact testing into simulated bone with snap lock testing of cannula and stylet handles, hipot testing, continuity testing, visual analysis following impact testing, and Instron insertion and removal testing in simulated bone. All tests passed, showing substantial equivalence.

Mechanical and electrical safety testing was performed on the subject devices in accordance with IEC 60601-1:2005 Ed. 3, including Dielectric strength test, mechanical strength, push test, drop test, and mold stress relief test. Subject devices passed electrical safety testing.

Biocompatibility testing was conducted on gamma sterilized, finished devices per ISO 10993. Tests included cytotoxicity (MEM Elution testing), sensitization (Magnusson-Kligman Method), irritation (Intracutaneous Toxicity), systemic toxicity (Systemic Injection Test), material mediated pyrogen test (Rabbit Pyrogen Test), and hemolysis (Extract method test). All devices passed biocompatibility testing.

Sterility: Devices have been gamma sterilization validated in accordance with ISO 11137 using the VDmax25 method of validation. Sterility validation met requirements of ISO 11137.

Transit testing: Adopted from the PAK family of devices, using ISTA 1C Test (Environmental pre-conditioning, Compression test, Vibration test – fixed vibration, Vibration test – random vibration, Drop testing – corner, edge, and face drop), visual analysis, and inner/outer blister seal integrity testing. Packaging met transit testing requirements.

Sterile barrier heat sealing: Adopted from the PAK family of devices. Heat sealing process successfully validated.

Shelf life testing (device): 36 month accelerated aging of packaged devices followed by functional use testing. Testing in progress.

Shelf life testing (packaging): 36 month accelerated aging of packaging followed by seal strength testing, package conditioning, and seal integrity testing. 36 month shelf life successfully validated.

Clinical Study:
A cadaver lab test was conducted where the subject devices, connected to the Medtronic NIM® System, were successfully used to create a pilot hole which was successfully tapped and fitted with a pedicle screw. The results validated that the device design outputs met the user needs (design inputs).

Key Results: The subject device was shown to be substantially equivalent to the predicate devices through dimensional and functional testing, and cadaver lab testing confirmed successful performance for its intended use.

Premarket Notification

PEP BE-ST

BE-ST NIM® PAK Needle, Blunt, and Pedicle Probe

The subject devices were shown to be substantially equivalent to the predicate devices through dimensional and functional testing.

The main difference between the subject and predicate devices is the design of the handle. The subject devices also have an improved locking mechanism which allows the user to lock the stylet handle to the cannula with a quarter turn bayonet-type locking mechanism. In addition, an audible "click" provides the user with assurance that the handle is locked into place.

Additionally, the electrical insulation was changed from nylon to polyester. The polyester insulation material passed biocompatibility testing pursuant to ISO 10993-4. 10993-10, and 10993-11.

PEP BE-ST BE-ST NIM® PAK Needle, Blunt, and Pedicle Probe

BE-ST conducted a cadaver lab test where the subject devices, connected to the Medtronic NIM® System, were successfully used to create a pilot hole which was successfully tapped and fitted with a pedicle screw. The results of the lab validated that the device design outputs met the user needs (design inputs).

Pyrogen status for general medical devices was evaluated using the LAL test. Testing to monitor pyrogens will be performed periodically.

VIII. CONCLUSIONS

The subject device is only intended for use with the Medtronic NIM® System. As confirmed through bench, clinical, and lab testing; the subject device has the same safety and effectiveness profile as the predicate device.
