The XABO Catheters are used for cerebrospinal fluid (CSF) shunting.

The XABO Catheters are manufactured using barium sulfate fillcone elastomer and are impregnated with clindamycin hydrochloride and rifampicin designed to be released over time from the exterior and inner lumen surface once implanted.

The XABO Ventricular Catheters will be offered in 18 cm in length with an inner diameter of 1.2 mm and an outer diameter of 2.5 mm. Lengths are marked in 1 cm intervals starting from the catheter tip, thus enabling the surgeon to qauge the depth of penetration of the catheter into the lateral ventricle. The proximal end of the catheter has 16 flow holes around the catheter circumference.

Components supplied with the XABO Ventricular Catheter include a pre-loaded stainless steel stylet and depending on the confiquration may contain a deflector.

The XABO Peritoneal Catheters measure 60 cm or 120 cm in length, 1.2 mm in inner diameter, and 2.5 mm in outer diameter. There are no length markers or wall slits on the tip is open ended. The catheter may be trimmed to the proper length.

The XABO Catheters are designed to articulate with existing Miethke Shunt Systems, such as the M.blue Adjustable Shunt System. Miethke Shunt System GAV 2.0 and SA 2.0 Valves, proGAV 2.0 Adjustable Shunt System miniNAV valve, and the Miethke Shunt System (DSV, connectors, and reservoirs) cleared by FDA (K192266/K190174/K161853/K141687/K110206/K030698/K011030).

The provided text focuses on the 510(k) premarket notification for the XABO Ventricular Catheter, XABO Peritoneal Catheter, and XABO Catheter Set. It primarily addresses the substantial equivalence of these devices to existing predicate devices. While it mentions performance bench testing and specific tests performed, it does not explicitly state specific acceptance criteria values or detailed study results that would allow for a complete fill of the requested table.

The document indicates that the devices were tested against "performance specifications" and that the results "confirm that the XABO Catheters meet performance specifications." However, the exact numerical or qualitative specifications themselves are not provided.

Therefore, the following information is extracted directly from the provided text, and where information is not explicitly stated, it is noted as "Not explicitly stated in the provided text."

1. Table of Acceptance Criteria and Reported Device Performance

Ask a specific question about this device

The catheter is used for cerebrospinal fluid (CSF) shunting.

The ventricular catheter is part of the Miethke Shunt System. It is used to gain access to the cavities of the brain for shunting of excessive CSF.

The ventricular catheter will be offered in lengths of 18 cm or 25 cm with an inner diameter of 1.2 mm and an outer diameter of 2.5 mm. The ventricular catheter contains five stripe depth markers at 3, 5, 7, 10 and 13 cm from the catheter tip. The ventricular catheter is manufactured using barium sulfate filled silicone elastomer.

The purpose of this submission is to seek clearance for modifications to the ventricular catheter which is part of the Miethke Shunt System (K020728). This submission proposes the following modification:

• adding stripe depth markers at 4, 6, 8, 9, 11 and 12 cm and point markers at 1 cm intervals on both sides of the tubing starting at 3.5 cm to 12.5 cm from the catheter tip.

The ventricular catheter is designed to articulate with existing Miethke Shunt Systems, such as the M.blue Adjustable Shunt System, Miethke Shunt System GAV 2.0 and SA 2.0 Valves, proGAV 2.0 Adjustable Shunt System, proSA Progammable Shunt System, Miethke Shunt System miniNAV valve, Miethke Shunt System Gravity Assisted Valve (GAV), and the Miethke Shunt System (DSV, ShuntAssistant, paedi-GAV, connectors, and reservoirs) cleared by FDA (K192266/K190174/K161853/K141687/K120559/K110206/K103003/K062009/K031303/ K030698/K011030).

The provided text is a 510(k) summary for the Miethke Ventricular Catheter, which addresses a modification to an existing device rather than a new AI-powered diagnostic tool. Therefore, much of the requested information regarding AI study design, such as MRMC comparative effectiveness, standalone performance, training set details, and expert ground truth establishment, is not applicable to this document.

However, I can extract information related to the acceptance criteria and the study performed for this specific device, as it pertains to the physical catheter modification.

Here's the relevant information:

1. Table of acceptance criteria and the reported device performance:

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

• Sample Size: Not explicitly stated. The document mentions "All samples" in relation to meeting acceptance criteria, implying a test set was used, but the exact number is not provided.
• Data Provenance: Not explicitly stated, but it is implied to be from non-clinical laboratory performance testing.

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

• Not Applicable. This device is a physical medical device (catheter) and the testing performed relates to its physical properties (radiopacity) rather than diagnostic accuracy requiring expert interpretation for ground truth.

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

• Not Applicable. As mentioned above, this testing does not involve human interpretation or adjudication in the context of diagnostic accuracy.

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 is a physical medical device, not an AI-powered diagnostic tool.

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

• Not Applicable. This is a physical medical device, not an AI-powered diagnostic tool.

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

• For the radiopacity testing, the "ground truth" would be established by the physical measurements and standards defined in the ASTM F 640-12 standard test methods. This is an objective measurement rather than a subjective interpretation requiring expert consensus or pathology.

8. The sample size for the training set:

• Not Applicable. This is a physical medical device; there is no "training set" in the context of an AI algorithm.

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

• Not Applicable. There is no training set for this type of device.

Study Details:

• Study performed: Non-clinical laboratory performance testing.
• Standard used: ASTM F 640-12 standard test methods for determining radiopacity for Medical Use.
• Purpose: To demonstrate that the modification (additional depth markers) to the ventricular catheter maintains its intended performance, particularly regarding radiopacity, and is substantially equivalent to the predicate device.
