Intended Use

The Cantata® 2.9 Microcatheters are intended for use in small vessel or superselective anatomy for diagnostic and interventional procedures including neuro, peripheral, or coronary use.

Device Description

The Cantata 2.9 Microcatheters are braided microcatheters with hydrophilic coating, designed for use in small vessel or superselective anatomy for diagnostic and interventional procedures including neuro, peripheral, or coronary use. The devices include one radiopaque marker band to assist in fluoroscopic visualization of the catheter during use. The catheters are available in 2.9 French shafts and are available in 100, 110, 135, and 150 centimeter lengths. The devices are compatible with a 0.038 inch (0.97 millimeters) diameter angiographic catheter and can accept 0.018 inch (0.46 millimeters) and 0.021 inch (0.53 millimeters) diameter wire guides.

AI/ML Overview

The provided text describes performance testing for the Cantata® 2.9 Microcatheter. This is a medical device, not an AI/ML algorithm, therefore most of the requested information about AI model specifics (training set, experts, MRMC studies, etc.) is not applicable.

Here's the information that can be extracted relevant to the performance of the Cantata® 2.9 Microcatheter:

Study Information (Non-AI Device)

  1. Sample size used for the test set and the data provenance: Not explicitly stated for each test in terms of a "test set" for an algorithm. These are physical device tests. Sample sizes would refer to the number of physical devices or animal subjects used, which is not detailed beyond "test article(s)" or "animal model." The provenance is internal testing by Cook Incorporated, a U.S. company. The studies are prospective in nature, as they involve testing newly manufactured devices.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for these physical and biocompatibility tests is established through standardized methodologies and objective measurements, not expert consensus on interpretations.
  3. Adjudication method for the test set: Not applicable. Test results are objective measurements against predetermined physical or biological criteria.
  4. 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 not an AI/ML device.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI/ML device.
  6. The type of ground truth used:
    • Physical Properties: Objective measurements against engineering specifications (e.g., force in Newtons, pressure in kPa/psi, diameter in mm, radius in mm).
    • Biocompatibility: Established ISO standards and direct biological response (e.g., lysis score, sensitization response, observation of toxicity, hemolytic index, clotting time).
    • Functional Performance: Qualitative and quantitative assessment of device behavior in simulated environments (e.g., tracking through a tortuosity fixture, ability to deliver particles) or animal models (e.g., preparation, introduction, pushability, trackability, radiopacity).
  7. The sample size for the training set: Not applicable. This is not an AI/ML device.
  8. How the ground truth for the training set was established: Not applicable. This is not an AI/ML device.
