Intended Use

The Medline Reinforced Epidural Catheter is indicated for the injection of local anesthetics into the epidural space for patients over 22lbs. (10kg), for a duration of use up to 72 hours.

Device Description

The Medline Reinforced Epidural Catheter is a single use device made of flexible polyurethane elastomer tubing. The subject device is sold sterile, and will be packaged inside of a convenience kit alongside a variety of other components that are outside the scope of this 510(k) submission. The proposed epidural catheter is designed as a closed tip device with two eyelets to provide for the dispersion of anesthetic agents. The catheter features a 19G design and is 913 millimeters (mm) long. The catheter has a marked tip, with 10mm increments up the length of the device (up to 913mm). The 100mm mark is indicated by two marks, 150mm by three marks, 200mm by 4 marks, and 250mm by 5 marks. In addition, the Medline Reinforced Epidural Catheter has an internal radiopaque inner spring that is evenly distributed inside the device, terminating 2+/-0.05mm from the liquid outlet end. As an added safety feature, a solid wide warning mark is featured on the proposed device to indicate exit of the catheter from a needle when used in conjunction with an epidural needle.

AI/ML Overview

This document is a 510(k) premarket notification for a medical device (Medline Reinforced Epidural Catheter) and as such focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing. It does not include information typical of a study that would define acceptance criteria for AI/Algorithm-based device performance and then prove the device meets those criteria using clinical data and expert input.

Therefore, many of the requested elements (1-9) regarding acceptance criteria, reported performance, sample sizes for test/training sets, data provenance, expert involvement, adjudication methods, MRMC studies, standalone performance, and ground truth establishment for AI/algorithm performance are not applicable or not present in this document.

However, I can extract the information provided regarding the non-clinical testing and the company's conclusion of substantial equivalence.

Summary of Non-Clinical Testing and Conclusion of Substantial Equivalence:

The Medline Reinforced Epidural Catheter is seeking 510(k) clearance based on substantial equivalence to the ARROW® FlexTip Plus® Epidural Catheter (K140110). Instead of defining acceptance criteria for algorithmic performance, the submission focuses on demonstrating safety, performance, and functionality through various non-clinical tests.

No information provided in the document refers to an AI/algorithm-based device, nor does it contain data on acceptance criteria, reported device performance (in the context of AI), sample sizes for test/training sets, data provenance, expert involvement, adjudication methods, MRMC studies, standalone performance, or ground truth establishment relevant to AI/algorithm evaluation.

The document describes non-clinical testing for a physical medical device. Here's a summary of the non-clinical tests conducted:

1. Table of Acceptance Criteria and Reported Device Performance:

This document does not define quantitative acceptance criteria for algorithm performance or report such performance metrics. Instead, it lists various non-clinical tests conducted to demonstrate the safety and functionality of the physical catheter. The "reported device performance" is implied by the successful completion of these tests in accordance with relevant standards.

Regarding your specific questions:

  1. A table of acceptance criteria and the reported device performance: See the table above. Note that these are for a physical device, not an AI/algorithm.
  2. Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not applicable for an AI/algorithm. For the non-clinical tests, sample sizes would be defined by the selected standards and internal protocols, but are not specified in this summary. Data provenance is not specified.
  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 as this is not an AI/algorithm study requiring ground truth derived from expert consensus.
  4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable for non-clinical testing of a physical device.
  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: No, this is not an AI/algorithm device submission.
  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: No, this is not an AI/algorithm device submission.
  7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable as this is not an AI/algorithm study. The "ground truth" for a physical device is its ability to meet engineering specifications and safety standards through physical and chemical testing.
  8. The sample size for the training set: Not applicable; there is no training set mentioned, as this is not an AI/algorithm device.
  9. How the ground truth for the training set was established: Not applicable; there is no training set mentioned, as this is not an AI/algorithm device.

Conclusion stated in the document:
Based on the non-clinical testing, Medline Industries, Inc. concludes that the Medline Reinforced Epidural Catheter is substantially equivalent to the predicate device, ARROW® FlexTip Plus® Epidural Catheters (K140110).
