Intended Use

The Monteris Medical NeuroBlate™ System is indicated for use to ablate, necrotize, or coagulate soft tissue 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.

Device Story

NeuroBlate System provides MRI-guided laser thermal therapy for neurosurgery. Components: gas-cooled laser delivery probe (side-firing or diffusing tip), probe driver for stereotaxic positioning, electronics rack, and control workstation with M Vision software. System inputs: MRI images for trajectory planning and real-time thermographic monitoring. Operation: surgeon uses workstation to plan probe placement and monitor thermal ablation; system provides real-time thermographic analysis of MRI images. Output: visual feedback for physician to guide laser energy delivery. Benefit: precision thermal ablation of soft tissue. Used in clinical settings by neurosurgeons. Decision-making: physician interprets thermographic data to assess therapy; system output is adjunctive, not sole basis for patient management.

Clinical Evidence

Bench and animal testing demonstrated compliance with medical community expectations and product labeling. Testing confirmed the system functions effectively with both Diffusing-Tip and Side-Firing probes. No clinical human trial data presented.

Technological Characteristics

MRI-compatible laser surgical system. Energy source: 1064 nm laser. Components: gas-cooled laser delivery probe, probe driver, electronics rack, control workstation. Software: M Vision for planning and thermographic analysis. Connectivity: interfaces with MRI and hardware subsystems. Materials: identical to predicate.

Indications for Use

Indicated for ablation, necrosis, or coagulation of soft tissue via interstitial irradiation or thermal therapy in neurosurgery using 1064 nm lasers. Intended for use by trained physicians for MRI-guided trajectory planning and real-time thermographic analysis.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

### c. Descrintion of Device

The Monteris NeuroBlate™ System is a unique collection of MRI-compatible laser devices and accessories that create an MRI guided delivery of precision thermal therapy. The NeuroBlate System components consist of:

- A gas-cooled Laser Delivery Probe (Probe) to deliver controlled energy to a target . zone;
- A Probe Driver which allows the surgeon to precisely position, stabilize and . manipulate a laser probe within the target zone;
- . A System Electronics Rack and Components, which includes necessary umbilicals, cables, penetration panels, and small hardware for system mechanical, electrical, and electronic operation; and
- A Control Workstation including the M Vision™ Software, which includes a user . interface for procedure planning, interactive monitoring of NeuroBlate™ procedures, and interfaces to the MRI and hardware subsystems.

This submission adds a line of Diffusing Tip Laser Delivery Probes (DTP) to the existing line of Side-Firing Laser Delivery Probes.

#### d. Indications for Use

The Monteris Medical NeuroBlate™ System is indicated for use to ablate, necrotize, or coagulate soft tissue 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 Monteris Medical NeuroBlate™ System with the Side-Firing and Diffusing Tip Laser Delivery Probes is substantially equivalent to the predicate Monteris NeuroBlate™ System with only the Side-Firing Laser Delivery Probes in intended use. technology, design and physician use.

The Indications for Use for the modified NeuroBlate System are unchanged from the predicate NeuroBlate System. The fundamental technology is also unchanged.

All patient contacting materials are identical in composition, source, and use with respect to the predicate device.

{2}------------------------------------------------

The technical modes of action and technical principles are materially the same as the predicate devices.

The application System with the Diffusing-Tip Laser Delivery Probe can create larger ablation lesion volumes during laser firing than the predicate Side-Firing Probe. The Side-Firing Probe remains useful for fine-tuning the edges of an ablation target or for focal energy delivery if probe position within the target warrants such use.

Bench testing has demonstrated that the System is in compliance with the medical community's expectations and the product labeling. It demonstrates that NeuroBlate system works as well with the Diffusing-Tip Probe as it does with the Side-Firing Probe.

As the modifications presented in the current device do not change the intended use, operating principles, or raise any unaddressed safety concerns, with respect to the predicate device, it can be concluded the application NeuroBlate™ System with the added Diffusing Tip Laser Delivery Probe is substantially equivalent to the predicate NeuroBlate™ System.

### f. Summary of Supporting Data

Bench and animal testing has demonstrated that the System in general, and the DTP in particular, are in compliance with the medical community's expectations and the product labeling.
