Patient management decisions should not be made solely on the basis of the NeuroBlate System analysis.
Device Description
The Monteris NeuroBlate™ System is a collection of MRI-compatible laser devices and accessories that create an MRI guided delivery of precision thermal therapy that is currently indicated for the practice of neurosurgery. As previously described in K162762, K170724, the NeuroBlate System is typically used for the minimally invasive ablation of neurosurgeon identified target tissue (tumors, epileptic foci) in the brain. The NeuroBlate System components consist of: - Families of gas-cooled Laser Delivery Probe (Probe) (SideFire & FullFire) to deliver . controlled energy to a target zone. - . Probe Drivers (Advanced Probe Driver, Robotic Probe Driver) which allow the surgeon to precisely position, stabilize and manipulate a probe, endoscope or other device within the target zone. - . An Interface Platform, which attaches to the MRI system patient table and provides supporting electronics for the Advanced and Robotic Probe Drivers and interconnections for the Laser Delivery Probes; - . A System Electronics Rack and Components, which includes necessary umbilicals, cables, penetration panels, and small hardware for system mechanical, electrical, and electronic operation. - . A Control Workstation including the M-Vision™ and M-Vision Pro™ software, which includes a user interface for procedure planning, interactive monitoring of NeuroBlate procedures, and interfaces to the MRI and hardware subsystems. The NeuroBlate System is utilized with stereotaxic frames and patient stabilization systems, such as: - . The AXiiiS stereotaxic mini-frame and the Monteris Cranial Bolt and Mini-Bolt fixation components, and - The AtamA Stabilization System and MRI receive-only head coil, as well as, other optional accessories, including: drill bits, bolts, thumbscrews, instrument adaptors, accessory host adaptors, MRI trajectory wands, cranial screws, bone screws, fiducial markers, stereotactic manual driver with mandrel and T-handle, and other manual accessory instruments and tools.
More Information

No
The document describes a system for MRI-guided laser ablation with planning and monitoring software, but there is no mention of AI or ML in the device description, intended use, or the sections specifically checked for these terms. The focus is on hardware, software for planning/monitoring, and thermal analysis based on MRI.

Yes
The device is indicated for use to "ablate, necrotize, or coagulate intracranial soft tissue, including brain structures, through internal therapy in medicine and surgery," which are therapeutic actions.

No.
The device is indicated for use to ablate, necrotize, or coagulate intracranial soft tissue. While it aids in planning and monitoring thermal therapies and provides information useful in determining thermal therapy, its primary function is therapeutic (ablation), not solely diagnostic. The text explicitly states "Patient management decisions should not be made solely on the basis of the NeuroBlate System analysis," further indicating it's not a standalone diagnostic tool.

No

The device description explicitly lists multiple hardware components, including laser delivery probes, probe drivers, an interface platform, and a system electronics rack, in addition to the software.

Based on the provided information, the Monteris Medical NeuroBlate System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • NeuroBlate System Function: The NeuroBlate System is a surgical device used for ablating, necrotizing, or coagulating intracranial soft tissue using lasers. It is a therapeutic device, not a diagnostic one.
  • Intended Use: The intended use clearly states its purpose is for "internal therapy in medicine and surgery in the discipline of neurosurgery." While it uses MRI for planning and monitoring, this is part of the surgical procedure, not an in vitro diagnostic test.
  • Device Description: The description details components like laser delivery probes, probe drivers, and a control workstation, all of which are consistent with a surgical system.
  • Lack of Specimen Analysis: There is no mention of the device analyzing any biological specimens from the patient.

Therefore, the NeuroBlate System falls under the category of a surgical or therapeutic device, not an In Vitro Diagnostic device.

or thermal therapy in medicine and surgery in the discipline of neurosurgery with 1064 nm lasers.

The clarified indications were determined to not create a new intended use or raise different questions of safety and effectiveness, and were also determined to not introduce any new or different technical characteristics which could raise different questions of safety and effectiveness, i.e., the clarified indications are more clearly consistent with the existing intended use as well as the exiting indications for use. This 510(k) submission meets the Traditional 510(k) criteria as the proposed changes involve a modification to the language of the indications for use to clarify the current indications.

Additionally, the proposed clarified indications were evaluated within the FDA General-Specific Guidance's 44 criteria which determined that the proposed labeling modifications are to provide clarification for the terminology utilized within the existing indications as the device is currently utilized and intended. The proposed changes are not intended to provide specific indications for use which are different than the current language.

The proposed clarified indications were also evaluated utilizing several other FDA Guidance Documents 15,16,17,18, which concluded that the modified Indications for Use clarify the terminology utilized within the existing indications as the device is currently used via its Intended use. The proposed changes are not intended to provide specific indications for use which are different than the current language.

The modified NeuroBlate has the same intended use and similar indications, and identical technological characteristics and principles of operation as the cleared NeuroBlate System. As explained in the attached 510(k) notice, the minor differences between the subject NeuroBlate and the predicate device do not raise any new questions of safety or effectiveness. Thus, we believe that the modified NeuroBlate System is substantially equivalent.

d. Indications for Use

The Monteris Medical NeuroBlate™ System is indicated for use to ablate, necrotize, or coagulate intracranial soft tissue, including brain structures, through interstitial irradiation or thermal therapy in medicine and surgery in the discipline of neurosurgery with 1064 nm lasers.

The Monteris Medical NeuroBlate™ System is intended for planning and monitoring thermal therapies under MRI visualization. It provides MRI based trajectory planning assistance for the stereotaxic placement of MRI compatible (conditional) NeuroBlate™ Laser Delivery Probes. It also provides real-time thermographic analysis of selected MRI images.

When interpreted by a trained physician, this System provides information that may be useful in the determination or assessment of thermal therapy. Patient management decisions should not be made solely on the basis of the NeuroBlate™ System analysis.

e. Comparison to Predicate Device

The application for the Monteris Medical NeuroBlate™ System with the modified labeling is substantially equivalent (and/ or identical) to the predicate Monteris NeuroBlate™ System (K162762, K170724) in intended use, indications for use, technology, design and physician use.

This submission proposes no physical changes to the NeuroBlate System hardware, software, accessories, manufacturing, design or the devices' specific step-by-step directions for use. This submission's intent is not to change the current indication or intended use. but to improve the indication's clarity, ease of understanding, and consistency with the intended use.

The indications for use are being clarified to ensure alignment and conformance with the currently cleared NeuroBlate System's intended use. This proposed change clarifies that the existing NeuroBlate (K162762) indications for use are in reference to the ablation of soft "brain" tissue, i.e.,

  • Current K162762. K170724 Indication (excerpt) states. . . to ablate "soft tissue" in "in the . discipline of neurosurgery" while utilizing "stereotaxic placement of MRI compatible (conditional) NeuroBlate™ Laser Delivery Probes". . .
  • Based on the K162762, K170724 provided Directions for Use, both textual statements ● and graphics demonstrate that the existing NeuroBlate System's intended use is to ablate brain tissue, i.e., brain tissue ablation refers to the ablation of "intracranial soft tissue," including "brain structures".

This clarification is based on the considerations that:

  • . Previous FDA cleared NeuroBlate System 510(k) submissions (e.g., K162762. K170724) demonstrate the device's intended use, based upon the submission contents and the associated proposed labeling and directions for use 19 is the ablation of brain tissue.
  • . The K162762. K170724 submitted NeuroBlate System content. labeling and directions for use included both textual and graphic brain tissue and skull specific

7

directions for use10 demonstrating the device's intended use1920 is brain tissue ablation.

  • As "brain soft tissue" is really the "matter" or "tissue" inside the patient's skull (or . cranium), the term "intracranial" is the appropriate medical terminology to describe the "soft tissue" to be ablated, i.e., "intracranial soft tissue".
  • . When physicians desire to identify specific "intracranial soft tissue" anatomical regions or areas within the brain, medical naming conventions divide the entire human brain into various areas or regions. While all these identified regions are "intracranial soft tissue", the generalized naming terminology for these intracranial soft tissue regions is "brain structures". Thus, as the NeuroBlate System is intended and indicated to ablate soft brain tissue, utilizing both "intracranial soft tissue" and "brain structure" naming conventions is appropriate in order to provide clarity and consistency between the Indications for Use and the Intended use.

The proposed labeling modifications:

  • Do not change the intended use, i.e., they only clarify the indications for use within the ● existing intended use,
  • . Do not raise new or different questions of safety and effectiveness,
  • . Do not introduce any new or different technical characteristics that raise different questions of safety and effectiveness,
  • Present no change to the NeuroBlate System's operating principles, design, . manufacturing, function or specific directions for use.

It can be concluded this NeuroBlate™ System application with the modified labeling would meet FDA's "non-significant change" criteria for which "changes to the device name or description that are consistent with the cleared indications for use and changes to improve readability or clarity that do not affect the substance of the indications for use"(21), i.e., a new 510(k) would not be necessary. However, having previously observed inconsistency in interpreting this guidance in coordination with general to specific use questions, a conservative approach was utilized and a new 510k submitted to demonstrate that the clarified indications are substantially equivalent to the described predicate devices.

The proposed clarified indications were also assessed utilizing the FDA General-to-Specific Guidance22 with the resulting conclusion being that the proposed Indications for use

19 United States Food and Drug Administration, the 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)], Guidance for Industry and Food and Drug Administration Staff. Washington, D.C.: FDA, 2014. http://www.fda.gov/downloads/MedicalDevices/.../UCM284443.pdf

modifications are to provide clarification for the existing terminology utilized within the existing indications as the device is currently utilized. The proposed changes are not intended to provide specific indications for use which are different than the current language.

The application for the NeuroBlate™ System with the modified labeling is substantially equivalent, and/ or identical, to the predicate Monteris NeuroBlate™ System (K162762, K170724) in intended use, technology, design and physician use

Thus, the predicate terminology describing brain tissue and brain structure ablation are all synonymous (identical) or equivalent, in intended use, technology, design and physician use.

Additionally, this submission proposes no manufacturing changes, process changes, materials changes, or technology proposed changes to the NeuroBlate System. The technical modes of action and technical principles remain the same as the predicate devices.

The fundamental functionality and technical characteristics of the proposed modified device is identical and substantially equivalent to the existing NeuroBlate System (K162762, K170724). The conclusion is that the difference in technological characteristics between proposed modified device and the current NeuroBlate System (K162762, K170724) do not raise new or different questions of safety and effectiveness, i.e., the proposed modified device is as safe as the described predicate devices.

f. Summary of Supporting Data

Considering the proposed changes are labeling clarifications, the previously provided in-vitro (bench), and in-vivo (animal) data remains applicable, and are incorporated by reference.

Given that the modifications to the indications for use do not create a new intended use or raise new or different questions of safety or efficacy, clinical data are not necessary to demonstrate substantial equivalence.
