The BOLT(-DRILL) KITs are indicated to provide a cranial access for RAUMEDIC neurosurgical precision pressure catheters of the RAUMEDIC NEUROMONITORING-SYSTEM.

The DRILL KITs are indicated to provide a cranial access for RAUMEDIC neurosurgical precision pressure catheters of the RAUMEDIC NEUROMONITORING-SYSTEM.

The Tunneling KITs are indicated to provide a cranial access for catheters of the RAUMEDIC NEUROMONITORING-SYSTEM.

The RAUMEDIC® NEUROMONITORING-SYSTEM consists of several different models of probes and probe catheters capable of performing one or several different functions:

• Models with a dedicated lumen can be used for drainage of cerebrospinal fluid (CSF).
• Models equipped with ICP sensors can determine the level and change in intracranial pressure (ICP).
• Models equipped with temperature thermistors can monitor intracranial temperature.
• Models equipped with fiber optic sensors can monitor partial tissue oxygen pressure (ptiO2).

The RAUMEDIC® NEUROMONITORING-SYSTEM is intended to be used in conjunction with previously cleared RAUMEDIC® EASY logO Monitor (K130529), RAUMEDIC® MPR2 logO DATALOGGER (K171666), RAUMEDIC® NPS3 (K103206) or RAUMEDIC® NPS2 X (Brand name for NPS2 cleared in K103206).

The RAUMEDIC® NEUROMONITORING-SYSTEM includes components needed to facilitate the surgical implantation of NEUROVENT® catheters.

The RAUMEDIC® NEUROMONITORING-SYSTEM can be used in MR environment under specific constraints (MR conditional). Those constraints vary by device type, implantation method (bolting or tunneling), and magnetic field strength (1.5 or 3.0 Tesla).

The provided FDA 510(k) clearance letter for NEUROVENT Devices does not contain the specific details required to describe the acceptance criteria and the study that proves the device meets those criteria, particularly for performance metrics.

The document primarily focuses on:

• Device Identification: Listing all device names, regulation numbers, classification, and product codes.
• Regulatory Equivalence: Stating that the device is substantially equivalent to previously cleared predicate devices based on intended use, indications for use, and technological characteristics.
• Intended Use/Indications for Use: Detailed descriptions of what each NEUROVENT component is used for (e.g., ICP monitoring, CSF drainage, brain temperature, tissue oxygen partial pressure).
• MR Safety Testing: A list of ASTM and ISO/TS standards used to confirm the device's MR conditional status, along with the specific tests performed (magnetically induced displacement force, torque, image artifacts, heating, malfunction for various fields).

Crucially, the document explicitly states: "Based on performance testing and the available information concerning the referenced comparison devices, the RAUMEDIC® NEUROMONITORING-SYSTEM is equivalent in that: - The devices have the same intended use and indication for use. - Performance characteristics are suitable for designated indications for use."

However, it does NOT provide:

• A table of specific numerical acceptance criteria (e.g., ICP accuracy within X mmHg, temperature accuracy within Y °C, ptiO2 accuracy within Z mmHg).
• The reported device performance metrics against those criteria.
• Details about the "performance testing" beyond the MR safety tests. This implies that the performance characteristics (accuracy, precision, etc., for measuring ICP, temperature, ptiO2) were either derived from the predicate devices, established using bench testing, or considered suitable without presenting detailed clinical performance data in this 510(k) summary. Given the device type, it's highly likely a combination of bench and possibly animal/cadaveric testing, as well as reliance on the long-established performance of similar predicate devices, was used.
• Information about clinical study design. There is no mention of human subject data, test sets, training sets, ground truth establishment, expert adjudication, or MRMC studies. The phrases "anticipated clinical performance" and "does not raise new issues of safety or effectiveness" suggest reliance on the substantial equivalence principle rather than novel clinical trial data.

Therefore, based solely on the provided text, I cannot complete the requested information for acceptance criteria and the study proving the device meets them, beyond the MR safety aspects.

I will indicate "Not provided in the document" for sections where the information is missing.

1. A table of acceptance criteria and the reported device performance

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size for test set: Not provided in the document. The document primarily refers to "performance testing" and "MR safety requirements" being "tested and confirmed" to meet standards, rather than a clinical test set from human subjects.
• Data provenance: Not provided. The MR safety tests are likely laboratory-based.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• Not applicable/Not provided. The document does not describe a study involving expert-established ground truth for performance evaluation of vital sign monitoring. The evaluation methodology focuses on substantial equivalence and laboratory testing for MR compatibility.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable/Not provided.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• Not applicable. This device is a monitoring system and a kit for surgical access, not an AI-assisted diagnostic tool for human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

• Not applicable. The performance evaluation discussed pertains to the physical and functional aspects of the hardware (catheters, sensors, and their compatibility with MR environments), not a standalone algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• For the MR safety testing, the "ground truth" would be established by the specifications and measurement techniques defined in the referenced ASTM and ISO/TS standards.
• For the core physiological measurements (ICP, temp, ptiO2), the "ground truth" would typically refer to the accuracy of the sensors against calibrated reference standards in laboratory or animal models. This specific detail is not provided, but it's implied compliance with recognized industry standards or internal validation that is deemed "suitable for designated indications for use" and "equivalent."

8. The sample size for the training set

• Not applicable. The document does not describe the use of machine learning or AI, and therefore, no "training set."

9. How the ground truth for the training set was established

• Not applicable.
