The Cleveland Multiport Ventricular Catheter Set is indicated for gaining access to the ventricles of the brain for the removal of cerebrospinal fluid (CSF) or for injecting Cytarabine.

Device Description

The Cleveland Multiport Ventricular Catheter contains a main or central lumen for the insertion stylet which is surrounded by four minor lumens (equally spaced) that contain the microcatheters. The catheter includes a ribbed distal tip, a housing for locking the insertion stylet, and proximal male Luer fittings at the end of each micro-catheter. The ribbed distal tip of the main catheter allows the micro-catheters to retract into the main catheter, by stretching the catheter when the insertion stylet is fully inserted and locked. This stretched state allows the catheter tip outside diameter to reduce slightly for atraumatic insertion into the ventricles of the brain. Once the insertion stylet is removed the catheter tip returns to its relaxed state (larger outside diameter) and the micro-catheters deploy. The enlarged tip aids in backflow prevention during injection of fluids. The distal Luer fittings allow for connectivity to a standard syringe or infusion pumps for removal of CSF and/or infusion. The biocompatible metal insertion stylet provides temporary rigidity to the distal portion of the device during catheter insertion and is removed after placement. The Cleveland Multiport Ventricular Catheter has no software, power sources, or radiation emitting components.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device called the "Cleveland Multiport Ventricular Catheter Set." This submission is to demonstrate that the new device is substantially equivalent to legally marketed predicate devices. The document refers to various tests performed to support this claim, but it does not describe an AI/ML powered device, an acceptance criteria table with reported device performance in the context of AI/ML, nor does it include information about sample sizes for test sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone algorithm performance, or ground truth establishment for AI/ML models.

The information provided relates to the physical and functional aspects of a traditional medical device (a catheter) and its comparison to existing catheters. Therefore, most of the requested fields are not applicable to the given text.

Here's an attempt to answer the applicable parts of your request based on the provided text, while explicitly stating when information is not available or not applicable:

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

This information is not provided in the document. The tests performed are bench tests and cadaver usability testing, not studies on patient data.

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)

This information is not applicable as the device is a physical medical instrument, not an AI/ML algorithm requiring expert ground truth for interpretation. The "cadaver usability testing" implies a medical professional would have evaluated the device's placement, but details are not given.

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

This information is not applicable as the device is a physical medical instrument, not an AI/ML algorithm requiring adjudication of interpretations.

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

A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for AI/ML-powered interpretive devices, which this catheter is not.

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

A standalone algorithm performance study was not done. This is not an AI/ML device.

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

The "ground truth" for the performance tests was based on engineering specifications, physical measurements, and established medical device testing standards (e.g., ISO standards for biocompatibility, LAL validation). For the cadaver assessment, the "ground truth" was successful placement and visualization on CT, implying a practical assessment against expected physiological outcomes.

8. The sample size for the training set

This information is not applicable as this is not an AI/ML device and therefore does not have a "training set."

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

This information is not applicable as this is not an AI/ML device and therefore does not have a "training set" or ground truth for one.
