The DuraMax™.018 Biliary Stent System is indicated for palliation of malignant neoplasms in the biliary tree

Device Description

The DuraMax™.018 Biliary Stent Delivery System is a balloon- expandable 316L stainless steel stent pre-mounted on a delivery catheter. The delivery catheter is an Over-the-Wire (OTW) design with a distal balloon and two radiopaque markers to aid in the placement of the stent. The proximal end of the catheter has a Y-connector that allows for the use of a guidewire ≤0.018" and the attachment of a balloon inflation device via a standard luer connector. Stents sizes include diameters of 5, 6 & 7 mm in lengths of 13, and 18 mm. The catheter is available in two working lengths, 80 cm and 135 cm. Shaft markers at 93 and 103 cm are provided on the 135 cm catheter. The catheter system is provided sterile and is intended for one use only.

AI/ML Overview

The DuraMax™ .018 Biliary Stent System has achieved substantial equivalence based on a comparison to a predicate device and extensive non-clinical testing. Here's a breakdown of the acceptance criteria and supporting studies:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance CriterionReported Device PerformanceStudy Proving Acceptance
BiocompatibilityDevice passed all biocompatibility testing.Biocompatibility testing
Material CompositionConstructed of similar materials to predicate device.Non-clinical design verification tests and analyses
Sizes (Diameter & Length)Available in similar diameters and lengths (5, 6, 7 mm diameters; 13, 18 mm lengths) to predicate and other marketed biliary stents.Non-clinical design verification tests and analyses
DesignSimilar design to predicate device (balloon-expandable 316L stainless steel stent pre-mounted on an OTW delivery catheter with distal balloon and two radiopaque markers).Non-clinical design verification tests and analyses
Indications for UseSame indications as predicate device: palliation of malignant neoplasms in the biliary tree.Comparison to predicate device's indications
Safety and EffectivenessDemonstrated through non-clinical design verification tests and analyses.Bench and Biocompatibility testing

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

The provided document does not mention any human clinical study or "test set" in the context of a comparative effectiveness study with human subjects. The safety and effectiveness were demonstrated using "non-clinical design verification tests and analyses" and "bench and Biocompatibility testing." Therefore, information on sample size for a test set and data provenance (country of origin, retrospective/prospective) is not applicable in this case.

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

This information is not applicable as the document does not describe a study involving human experts establishing ground truth for a test set. The evaluation was based on non-clinical testing and comparison to a predicate device.

4. Adjudication Method for the Test Set

This information is not applicable as the document does not describe a study involving human experts and adjudication for a test set.

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

There is no mention of an MRMC comparative effectiveness study, AI assistance, or human readers improving with AI in the provided documents. The DuraMax™ .018 Biliary Stent System appears to be a medical device (stent and delivery system), not an AI-powered diagnostic or assistive tool.

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

This is not applicable as the DuraMax™ .018 Biliary Stent System is a physical medical device, not an algorithm, and its performance would not be evaluated in a "standalone" algorithmic context.

7. The Type of Ground Truth Used

The ground truth for the device's performance was established through:

  • Non-clinical design verification tests and analyses (Bench testing): This refers to laboratory testing to evaluate the device's physical properties, mechanical performance, and functional characteristics against predetermined specifications.
  • Biocompatibility testing: This confirms that the materials used in the device are safe for contact with the human body and do not elicit adverse biological responses.
  • Comparison to a predicate device: The device's characteristics and intended use were deemed "substantially equivalent" to the Cordis® PALMAZ® GENESIS™ Transhepatic Biliary Stent on SLALOM .018" Delivery System, implying that the predicate's established safe and effective performance serves as a benchmark for the DuraMax system.

8. The Sample Size for the Training Set

This information is not applicable. The DuraMax™ .018 Biliary Stent System is a physical medical device, not a machine learning model, and therefore did not undergo "training" with a dataset in that sense. The "training" in this context would likely refer to the design, engineering, and manufacturing processes that led to the device's creation.

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

This information is not applicable for the same reasons as #8. The "ground truth" for the device's design and manufacturing would be established through engineering principles, material science, and quality control processes to ensure it meets its specifications.

Dear Mr. Shy:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been rcclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act and the limitations described below. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

The Office of Device Evaluation has determined that there is a reasonable likelihood that this device will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings section of the device's labeling:

The safety and effectiveness of this device for use in the vascular system have not been established.

Furthermore, the indication for biliary use must be prominently displayed in all labeling, including pouch, box, and carton labels, instructions for use, and other promotional materials, in close proximity to the trade name, of a similar point size, and in bold print.

§ 876.5010 Biliary catheter and accessories.

(a)
Identification. A biliary catheter and accessories is a tubular flexible device used for temporary or prolonged drainage of the biliary tract, for splinting of the bile duct during healing, or for preventing stricture of the bile duct. This generic type of device may include a bile collecting bag that is attached to the biliary catheter by a connector and fastened to the patient with a strap.(b)
Classification. Class II (special controls). The device, when it is a bile collecting bag or a surgical biliary catheter that does not include a balloon component, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.
