Intended Use

Phenom® Catheters are intended for the introduction of interventional devices and infusion of diagnostic or therapeutic agents into the neuro, peripheral, and coronary vasculatures.

Device Description

The Phenom® 27 Catheters are variable stiffness, single lumen catheters designed to access small, tortuous vasculature. They are available in a variety of lengths, stiffness and inner and outer diameters. The outer surface of the catheter is coated to aid in navigation in the vessel. The catheter also incorporates a liner to facilitate movement of introduction devices passing through its lumen. The distal tip has radiopaque marker(s) to aid visualization and positioning under fluoroscopy.

AI/ML Overview

This document describes the pre-clinical bench testing conducted for the Phenom® 27 Catheter, a medical device. The purpose of the study was to demonstrate that a modified version of the catheter (with an increased effective length) is substantially equivalent to the previously cleared predicate device.

Here's an analysis of the acceptance criteria and study as per your request:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state formal "acceptance criteria" with numerical thresholds for each test. Instead, it describes each test, its purpose, and concludes with a qualitative "Results" section, often stating that the results are "within the expected range" or "equivalent" to the predicate device, or that all samples "passed."

Here's an adapted table based on the provided information, interpreting the "Test Method Summary" as implicitly defining the acceptance criteria (i.e., meeting the standard, providing a reference, or demonstrating functional equivalence) and "Results" as the device's performance against these criteria.

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

  • Sample Size: The document does not explicitly state the numerical sample size for each test (e.g., "n=X catheters were tested"). It uses phrases like "All test samples," "All samples," or implies multiple units were tested (e.g., "Flow rate data was collected for the modified (160cm) device and the predicate device (150cm)").
  • Data Provenance: The study described is a pre-clinical bench testing study. This means the data was generated in a laboratory setting, not from human or animal subjects. The provenance is internal Cathera, Inc. testing, not from any specific country of origin in terms of patient data. It is prospective in the sense that the testing was conducted on the modified device to demonstrate its performance.

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

  • This information is not applicable as the study is a pre-clinical bench test of a physical device, not an AI/imaging diagnostic study that requires expert ground truth for interpretation.

4. Adjudication Method for the Test Set

  • This information is not applicable as the study is a pre-clinical bench test of a physical device, not an AI/imaging diagnostic study that requires human adjudication. The "results" are objective measurements or observations against predefined standards or comparison with a predicate device.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

  • No, an MRMC comparative effectiveness study was not done. This type of study is relevant for evaluating the impact of an AI system on human reader performance for diagnostic tasks, which is not the subject of this document.

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

  • No, a standalone algorithm performance study was not done. This document describes the bench testing of a physical medical device (catheter), not an AI algorithm.

7. The Type of Ground Truth Used

  • The "ground truth" for this pre-clinical bench testing is based on engineering specifications, international and national standards (e.g., ISO 10555-1, BS EN 13868:2002, BS EN 1707:1997), and comparison to the established performance of the legally marketed predicate device. For example, for flow rate, the "expected range" and "equivalence" to the predicate served as the reference. For dimensional verification, the "specified attributes" were the ground truth. For accessibility/tractability, reaching the M1 region of the neurovascular model was the ground truth for success.

8. The Sample Size for the Training Set

  • This information is not applicable as this document describes the testing of a physical medical device, not an AI system that requires a "training set."

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

  • This information is not applicable for the same reason as point 8.

Table A-Summary of Technological Characteristics, Components and Materials

{5}------------------------------------------------

Conclusion- Based on the comparison shown in Table A (above), the technological characteristic of the modified Phenom® 27 and the predicate Phenom® 27 are equivalent. The only design modification was to increase the effective length from 150 cm to 160 cm. This provides the user with additional length during the set-up procedure which does not alter the intended use or the fundamental scientific technology of the device as originally cleared for the predicate device and therefore substantially equivalent.

Performance Testing - Bench

As identified in the risk analysis, the increased length would require testing of the flow rate and dead space volume. Testing was conducted according to the same method used for the original predicate device. Accessibility and tractability testing was performed to verify that modified catheter can reach M1 region of tortuous neurovascular model. The modification to add extra length to the catheter did not affect the design or function of the distal shaft of the catheter that enters the body. All other tests performed on the predicate device apply to the modified version. A summary of the pre-clinical bench testing performed for the Phenom® 27 Catheter and the modified Phenom® 27 Catheter is presented in the Table B below:
