Intended Use

The use of IRRAflow Active Fluid Exchange System is intracranial pressure monitoring is required, and for externally draining intracranial fluid, as a means of reducing intracranial pressure in patients where an external drainage and monitoring system is needed.

Device Description

The IRRAflow® Active Fluid Exchange System (AFES) is an intracranial pressure (ICP) monitoring and drainage system intended for use by professional medical hospital personnel, trained and experienced in neurosurgical medical care. The drainage flow of cerebrospinal fluid (CSF) into the IRRAflow Catheter is uni-directional and gravity-driven; there is no recirculation of the CSF. A parallel line from the saline infusion bag is used in case clearance at the tip of the catheter is required. The IRRAflow Tube Set has a cassette that clicks on to the IRRAflow Control Unit and aligns the tubing against a peristaltic pump and pinch valve. The IRRAflow Drainage Collection System is attached to the Control Unit, using the Laser Leveler for defining the height of the Drainage Collection System relative to the catheter's tip position in the patient's head. This positioning is used for controlling the speed of drainage. The tubing and catheter can be disconnected and connected by standard Luer-Lock connectors. Settings can be changed via the user interface on the Control Unit. The default mode provides drainage and measuring ICP, allowing bolus injections when indicated. The bolus injections allow the catheter to be flushed when it becomes clogged. CSF or intracranial fluid samples can be taken from the Drainage Collection System.

AI/ML Overview

The provided text is a 510(k) premarket notification decision letter from the FDA regarding the IRRAflow Active Fluid Exchange System (AFES). The purpose of this submission is to demonstrate substantial equivalence to a previously cleared predicate device, specifically regarding changes to the Tube Set and Drainage Collection System. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are focused on demonstrating that the modified device's performance is equivalent to, or better than, the predicate device.

Here's an analysis based on the provided document:

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

The document does not explicitly present a table of quantitative acceptance criteria alongside numerical performance results for the device. Instead, it relies on a "PASS" or "FAIL" outcome for various verification and validation tests. The acceptance criteria for these tests are implied to be established by the test protocols and industry standards (e.g., "Pressure accuracy per protocol," "Durability, flow and freedom from leakage per protocol").

Here's a table summarizing the tests performed and their reported outcomes:

Test CategoryTest PerformedReported Device Performance (Result)
Biocompatibility TestingCytotoxicity (MEM Elution)PASS
Sensitization TestPASS
Irritation/Intracutaneous Reactivity TestPASS
Acute Systemic Toxicity, Injection TestPASS
Systemic Toxicity, Mediated PyrogenPASS
Genotoxicity (on various strains of bacteria)PASS
Genotoxicity (on mouse lymphoma cells)PASS
Bench and Electrical TestingElectrical Requirements Verification (Pressure accuracy)PASS
Mechanical Performance Verification (Durability, flow, freedom from leakage)PASS
Life Cycle Verification Test (Simulated use for reliability)PASS
Shelf Life / Package Integrity TestingSimulated Distribution Test (ASTM D4332-14, ASTM D4169-22 Cycle 13)PASS
Package Integrity Test (ASTM F1886-16, ASTM F2096-11)PASS
Package Seal Strength Test (EN 868-5:2009)PASS
Aging Test (Accelerated and real-time aging)PASS
Sterilization TestingSterilization Process Validation (Ethylene Oxide for Cassette and Drainage System)PASS

2. Sample size used for the test set and the data provenance

The document does not specify the sample sizes used for any of the tests listed in Table 3.
The data provenance is not explicitly stated beyond general descriptions of the tests (e.g., "The Minimal Essential Media (MEM) Elution test," "This test was designed to evaluate the allergenic potential"). There is no mention of country of origin or whether the tests were retrospective or prospective. Given the nature of these tests (bench, electrical, biocompatibility, sterilization validation), they are typically conducted as prospective laboratory studies rather than clinical studies using patient data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This information is not provided in the document. The tests performed are primarily engineering and laboratory-based, often following standardized protocols. Therefore, the concept of "ground truth" established by clinical experts (like radiologists for imaging devices) would not directly apply to these types of performance tests. The "ground truth" here is implied by adherence to established test methods and acceptable performance limits defined by those methods.

4. Adjudication method for the test set

This information is not provided and is generally not applicable to the types of performance tests described (biocompatibility, electrical, mechanical, shelf life, sterilization). Adjudication methods like 2+1 or 3+1 are typically used in clinical studies where multiple human readers interpret data (e.g., medical images) and a consensus is needed to establish a definitive ground truth.

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

There is no indication that a multi-reader multi-case (MRMC) comparative effectiveness study was done. The device is a physical system for fluid exchange and pressure monitoring, not an AI-powered diagnostic tool for image interpretation or similar tasks that would typically involve human readers and AI assistance.

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

This question is not applicable as the IRRAflow AFES is a medical device for intracranial pressure monitoring and fluid drainage, not an algorithm or AI system. Its performance is evaluated through engineering and biological safety tests.

7. The type of ground truth used

For the performance tests described (biocompatibility, electrical, mechanical, shelf life, sterilization), the "ground truth" is based on:

  • Established Test Standards and Protocols: Such as ASTM D4332-14, ASTM D4169-22 Cycle 13, ASTM F1886-16, ASTM F2096-11, EN 868-5:2009.
  • Defined Acceptance Criteria: These criteria are inherent to the test methods and are designed to ensure safety and effectiveness (e.g., pressure accuracy per protocol, freedom from leakage per protocol).
  • Laboratory Measurements and Observations: The results are direct measurements or observations within controlled laboratory environments.

It's not "expert consensus," "pathology," or "outcomes data" in the clinical sense, but rather adherence to predefined engineering and biological safety specifications.

8. The sample size for the training set

This question is not applicable because the IRRAflow AFES is a hardware medical device with specific Tube Set and Drainage Collection System modifications, not a machine learning or AI model that requires a "training set."

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

This question is not applicable as there is no training set for this device.

Conclusion

The IRRAflow® AFES is substantially equivalent to the predicate device (K222471). The IRRAflow® AFES has the same Indications for Use, similar technological characteristics, and the same principles of operation as the predicate device. Performance testing demonstrates the changes to the Tube Set designated as version 3.0 and Drainage Collection System do not change or adversely impact the operational parameters of the IRRAflow® System.
