Intended Use

The 8F Modified Sheath System is indicated for the introduction of interventional devices into the peripheral and neuro vasculature.

Device Description

The 8F Modified Sheath System is comprised of a Sheath, a Navigating Catheter, and an RHV (rotating hemostasis valve). The Sheath is a single-lumen, variable stiffness catheter with a radiopaque marker on the distal end. The inner lumen of the catheter is compatible with 8F or smaller catheters. The Dilator may be placed within the Sheath to facilitate percutaneous introduction of the Sheath into a femoral artery. The Dilator has a radiopaque marker at the distal tip. The Navigating Catheter is a singlelumen, variable stiffness catheter with a radiopaque marker at the distal tip. The Navigating Catheter is compatible with the Sheath and has a shaped distal end to facilitate placement. All of the catheters are coated with hydrophilic coating.

AI/ML Overview

The provided text describes the 8F Modified Sheath System and its substantial equivalence to a predicate device (Base Camp® Sheath System, K191717) for FDA clearance. The document focuses on non-clinical testing to demonstrate performance.

Here's an analysis based on your requested information:

1. Table of Acceptance Criteria and Reported Device Performance

The document lists various performance tests and their outcomes, uniformly indicating "PASS" and that "The pre-determined acceptance criteria were met." However, it does not explicitly state the specific quantitative acceptance criteria for each test. It only reports that the device met them.

2. Sample Size Used for the Test Set and the Data Provenance

The document does not explicitly state the sample sizes used for each of the performance or biocompatibility tests. It refers to "test specimens" or animals (e.g., "guinea pig," "rabbits," "mice") for biocompatibility, but without specific numbers.

  • Data Provenance: The data provenance is from non-clinical bench testing and laboratory animal testing. There is no information provided about the country of origin, but given it's an FDA submission, the tests were conducted to international standards (e.g., ISO, ASTM) which are globally recognized. All testing appears to be prospective (conducted specifically for this submission).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

Not applicable. This is a submission for a medical device (catheter system) where "ground truth" in the clinical sense (e.g., diagnosis, outcome) is not relevant for the non-clinical and biocompatibility studies presented. The "truth" or acceptance is determined by predefined engineering specifications and regulatory standards (ISO, ASTM). The document does not mention the use of human experts to establish ground truth for this type of testing.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods (like 2+1, 3+1) are typically used in clinical studies or studies involving human interpretation of data (e.g., medical imaging) to resolve discrepancies. The studies described are objective performance and biocompatibility tests where a result either meets or does not meet a predefined standard.

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 (catheter system), not an AI/software device. No MRMC study was conducted or is relevant.

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 algorithm or AI system.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc)

As mentioned in point 3, the concept of "ground truth" in the clinical diagnostic sense is not applicable here. For the performance and biocompatibility studies, the "ground truth" is defined by:

  • Pre-determined engineering specifications: For dimensional verification, tensile strength, kink resistance, etc.
  • International standards and regulatory guidelines: Such as ISO 80369-7:2016 for Luer Integrity, ISO 10555-1:2013 for leakage and burst pressure, and ISO 10993-1 for biocompatibility.

8. The Sample Size for the Training Set

Not applicable. There is no "training set" in the context of this traditional medical device submission. Training sets are relevant for machine learning or AI models.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no training set.
