Intended Use

The FluidiTube® 2.7F Infusion Micro Catheter is intended to facilitate infusion of contrast media into all peripheral vessels up to and including the cervical vessels, all vessels in the lower and upper extremities, visceral vessels and all coronary vessels. It is also intended for drug infusion in intra-arterial therapy and embolic materials for hemostasis. The FluidiTube® 2.7F Infusion Micro Catheter is not to be used in cerebral blood vessels.

Device Description

The FluidiTube® 2.7F Infusion Micro Catheter is a tapered 2.7F/2.9F single lumen catheter with a luer lock hub designed to facilitate the access of distal vasculature over a guidewire. The FluidiTube® has a semi-rigid proximal shaft that becomes progressively more flexible towards the distal end. The shaft is reinforced with braided stainless steel wire for kink resistance. The inner lumen is lined with a lubricious material to facilitate the movement of a guidewire. The outer surface of the catheter has a hydrophilic coating that becomes lubricious when wet with saline or blood. The FluidiTube® catheter is introduced to the target location through a guiding catheter 0.038" (0.97 mm) or larger and is compatible with 0.021" (0.53 mm) guidewires or smaller. Device configurations consist of one profile size (2.7F) with two different usable lengths (110cm, 130cm). The final device is packaged in a Tyvek pouch and sterilized by ethylene oxide (EO). The device is for single use only.

AI/ML Overview

The document provided is a 510(k) premarket notification for the Callisyn FluidiTube® 2.7F Infusion Micro Catheter. This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device rather than full clinical trials for novel devices. Therefore, the "acceptance criteria" and "device performance" are typically framed in terms of equivalence to the predicate and meeting established engineering and biocompatibility standards, rather than specific performance metrics like sensitivity/specificity for diagnostic devices.

Here's a breakdown of the requested information based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

Given that this is a 510(k) for a medical device (infusion micro catheter), "acceptance criteria" and "device performance" are defined by the comprehensive non-clinical testing and a comparative animal study demonstrating equivalence to the predicate device. The performance is assessed against established engineering standards and functional requirements relevant to the device's intended use.

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

  • Test Set Sample Size: For the simulated use environment (animal study), the document states the study was conducted in "a healthy male Yorkshire swine." This indicates a sample size of one animal.
  • Data Provenance: The animal study was prospective, conducted in a simulated use environment using an animal model (Yorkshire swine). The country of origin of the data is not explicitly stated, but it's part of a submission to the U.S. FDA.

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

  • Number of Experts: Two operators (presumably veterinarians or interventional specialists/researchers experienced in animal models for medical device testing) participated in the animal study.
  • Qualifications of Experts: Their specific qualifications (e.g., years of experience, specific board certifications) are not detailed in the document. They are referred to as "Operators."

4. Adjudication Method for the Test Set

The document states: "Both Operators rated all test and control microcatheters as acceptable for:" followed by a list of performance criteria. This implies that:

  • There was no explicit adjudication method described beyond the consensus or agreement of the two operators on the "acceptable" rating for all performance features.
  • It appears to be a 100% agreement or shared determination approach, as both operators individually rated them as acceptable, and the conclusion mentions "both Operators determined that all study protocol specified acute performance requirements...were successfully met."

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study was done. This type of study is more common for diagnostic imaging devices where reader performance is a key metric. For an infusion microcatheter, the focus is on device function, safety, and equivalence to established products.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Not applicable. This device is a physical medical instrument, an infusion microcatheter, not an algorithm or AI system. Therefore, a standalone performance study in the context of an algorithm is not relevant.

7. Type of Ground Truth Used (for the animal study / simulated use)

For the animal study, the "ground truth" was established by the direct observation and qualitative assessment by the two experienced operators during and after the procedure in the swine model. This included visual inspection for tracking success, fluoroscopic visualization, compatibility with other devices, functional performance (infusion), and post-procedure integrity assessment of the catheter and animal vasculature. This falls under expert observation/assessment in a simulated environment.

8. Sample Size for the Training Set

Not applicable. This device does not involve a "training set" in the context of machine learning. The non-clinical testing (biocompatibility, physical/mechanical) establishes the device's inherent properties and performance against specifications.

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

Not applicable. As stated above, there is no "training set" in the machine learning sense for this medical device. The "ground truth" for the non-clinical testing is based on established engineering standards, ISO standards, and other recognized methodologies (e.g., ASTM, USP).

{6}------------------------------------------------

8. SUMMARY OF CLINICAL TESTING AS BASIS FOR SUBSTANTIAL EQUIVALENCE

Clinical testing was not conducted to evaluate substantial equivalence. Usability testing was conducted in an animal model under a simulated use environment to validate the performance of the device. Callisyn FluidiTube® 2.7F Infusion Micro Catheters were compared to Progreat® 2.7 F Microcatheters in a healthy male Yorkshire swine. Operators successfully tracked the microcatheters into the right artery, the hepatic arteries, and the contralateral iliac artery, and injected the representative diagnostic (non-ionic contrast media Omnipaque 300), therapeutic (Heparin), and embolic material (embolic microspheres 500-700μm) through each microcatheter into the hepatic arteries as required by the protocol. Both Operators rated all test and control microcatheters as acceptable for:

  • . Ability to flush the packaging hoop and remove the microcatheter from the hoop without damage
  • Ability to track the microcatheter through all three vessels and visualize them ● fluoroscopically
  • Compatibility with the guidewire (0.014 in the RCA, 0.021 in the hepatic . artery, and 0.018 in the iliac artery)
  • . Ability to visualize the device under fluoroscopy
  • Compatibility 1mL of heparin, 2mL of non-dilute contrast media, and 1mL of ● 500-700um embolic microspheres when injected into the hepatic artery
  • Integrity, with no kinking or damage to the tip ●

There was no damage to the catheters noted, no vascular dissection was observed, and no thrombus was observed on any catheter when removed from the animal.

After a thorough assessment of all test article performance features, including use in conjunction with common ancillary diagnostic and therapeutic products, both Operators determined that all study protocol specified acute performance requirements of the FluidiTube® were successfully met for this study and it is comparable to the Terumo Progreat® 2.7Fr Microcatheters predicate device.

9. CONCLUSIONS DRAWN FROM NON-CLINICAL AND CLINICAL TESTS

The Indications for Use, overall design, technological and performance characteristics of the FluidiTube® and Progreat® are substantially equivalent. Based on the data and evidence presented (e.g., performance testing, simulated use testing, etc.) for the FluidiTube®, Callisyn concludes that the device is substantially equivalent to the legally marketed micro catheter for its intended use. Differences between the proposed and predicate device do not raise any new issues of safety or effectiveness.
