The DYNALINK™ .035 Biliary Self-Expanding Stent System is indicated for palliation of malignant strictures in the biliary tree.

Device Description

The DYNALINK™ .035 Biliary Self-Expanding Stent System is a catheter designed to deploy a self-expanding nickel titanium (Nitinol) stent into the biliary tree.

The catheter body is constructed from two coaxial members. The inner member (IM) is compatible with a .035" guide wire in an over-the-wire configuration. The outer member (OM) is composed of a distal sheath that constrains the unexpanded stent, an outer shaft over most of the catheter length, and a proximal handle used to retract the assembly.

AI/ML Overview

The acceptance criteria and the study proving the device meets these criteria are described below:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria (Performance Metric)Device Performance as Reported in the Submission
Safety and EffectivenessDemonstrated through data collected from in vitro bench tests and analyses.
Technological CharacteristicsSubstantially equivalent to currently marketed predicate devices (K011881) in terms of materials, biocompatibility, performance properties, sterilization, and packaging.

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

The document does not detail specific sample sizes for a "test set" in the context of clinical or human data. The performance data primarily relies on "in vitro bench tests and analyses." Therefore, information on data provenance (e.g., country of origin, retrospective/prospective) for a test set of human data is not applicable here.

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

This information is not provided. Since the performance data is based on in vitro bench tests, the concept of establishing ground truth by medical experts in the way it applies to clinical studies is not relevant.

4. Adjudication Method for the Test Set:

This information is not provided. As the performance data is from in vitro bench tests, adjudication methods typically used for interpreting human data are not applicable.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done and the effect size of how much human readers improve with AI vs without AI assistance:

No MRMC comparative effectiveness study was mentioned. The device is a physical medical device (a biliary stent system), not an AI-assisted diagnostic or interpretative tool. Therefore, this type of study is not relevant to this submission.

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

This is not applicable as the device is a physical stent system.

7. The Type of Ground Truth Used:

The ground truth for demonstrating safety and effectiveness was based on the results of in vitro bench tests and analyses. This would involve engineering specifications, material properties, mechanical testing results, and other laboratory-based evaluations.

8. The Sample Size for the Training Set:

This information is not provided. The concept of a "training set" in the context of developing an algorithm or AI model for diagnostic or predictive purposes is not applicable to this physical medical device. The "training" for such a device would typically involve engineering design, prototyping, and iterative bench testing.

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

This information is not explicitly detailed. For a physical device like a stent, "ground truth" during development (analogous to a training set for algorithms) would be established through engineering design specifications, materials science principles, and iterative bench testing to ensure the device met predetermined performance criteria (e.g., expansion force, radial strength, fatigue resistance, biocompatibility). These criteria would be based on established industry standards and clinical needs for biliary stent functionality.

Device Trade Name:DYNALINK™ .035 Biliary Self-Expanding Stent System
Device Common Name:Biliary Stent
Device Classification Name:Biliary Catheter
Device Classification:Class II

Summary of Substantial Equivalence:

The design, materials, method of delivery and intended use features of DYNALINK™ .035 Biliary Self-Expanding Stent System are substantially equivalent with regard to these features in the predicate device, the DYNALINK™ .035 Biliary Self-Expanding Stent System (K011881, July 18, 2001).

Device Description:

The DYNALINK™ .035 Biliary Self-Expanding Stent System is a catheter designed to deploy a self-expanding nickel titanium (Nitinol) stent into the biliary tree.

The catheter body is constructed from two coaxial members. The inner member (IM) is compatible with a .035" guide wire in an over-the-wire configuration. The outer member (OM) is composed of a distal sheath that constrains the unexpanded stent, an outer shaft over most of the catheter length, and a proximal handle used to retract the assembly.

Intended Use:

The DYNALINK™ .035 Biliary Self-Expanding Stent System is indicated for palliation of malignant strictures in the biliary tree.

Technological Characteristics:

Comparisons of the new and predicate devices show that technological characteristics such as materials, biocompatibility, performance properties, sterilization and packaging are substantially equivalent to the currently marketed predicate devices. The design modification of the new biliary stent system compared to that of the predicate biliary stent system is the length of the stent.

Performance Data:

The safety and effectiveness of the DYNALINK™ .035 Biliary Self-Expanding Stent System has been demonstrated through data collected from in vitro bench tests and analyses.

Dear Ms. Modjarrad:

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 reclassified 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.
