The Protégé™ Self-expanding Nitinol Stent with StarPort™ Delivery Technology is intended as a palliative treatment of malignant neoplasms in the biliary tree.
The Protégé™ stent is a self-expanding nitinol (nickel-titanium alloy) stent provided in multiple lengths, (20 - 80 mm) and diameters (6 - 12 mm). The stent is electropolished. The stent is premounted on an 80 or 120 cm working length, 0.035" over-the-wire delivery catheter designed for transhepatic access. Upon deployment, the stent achieves its predetermined diameter and exerts a constant, gentle outward force to establish patency in the biliary ducts. The disposable StarPort Delivery Technology system is comprised of an inner and outer sheath, which are locked together with a safety lock.
The provided document is a 510(k) Premarket Notification Summary for a medical device, the Protégé™ Self-expanding Nitinol Stent with StarPort™ Delivery Technology (Biliary Indication). It primarily focuses on demonstrating substantial equivalence to a predicate device and outlines the intended use and some regulatory aspects. This document does NOT contain information about specific acceptance criteria or a study that proves the device meets those criteria in the way a clinical trial or performance study report would.
The document states:
"The modified Protégé™ Self-expanding Nitinol Stent with StarPort™ Delivery Technology is substantially equivalent to the currently marketed Protégé™ Self-expanding Nitinol Stent with StarPort™ Delivery Technology (K012066) in intended use, materials, technological characteristics and performance. Stent lengths > 80 mm have been added to further expand the product offering."
This indicates that the manufacturer is claiming equivalence to an already approved device rather than presenting a performance study for this specific modified device against new, defined acceptance criteria. Therefore, most of the requested information regarding acceptance criteria, study details, and ground truth cannot be extracted from this summary.
Here's what can be inferred or explicitly stated based on the provided text, and what cannot:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not explicitly defined in the document for the modified device. | The modified device is "substantially equivalent" to the predicate device (K012066) in intended use, materials, technological characteristics, and performance. The modification primarily involves adding stent lengths > 80 mm. |
- Reasoning: The summary does not provide specific quantitative acceptance criteria (e.g., success rates, complication rates, patency rates) for the modified stent or a detailed performance report. The entire premise of this 510(k) is to demonstrate substantial equivalence to a legally marketed predicate device rather than fulfilling new, specific performance criteria through a dedicated study.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not applicable / Not mentioned. This document does not describe a clinical performance study with a test set.
- Data Provenance: Not applicable / Not mentioned. As there's no clinical performance study detailed, there's no data provenance information.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Not applicable / Not mentioned. No clinical performance study is described with a test set requiring expert ground truth establishment.
4. Adjudication Method for the Test Set
- Not applicable / Not mentioned. No clinical performance study is described with a test set requiring an adjudication method.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- Was an MRMC study done? No.
- Effect size of human readers with AI vs. without AI assistance: Not applicable. This device is a physical medical device (stent), not an AI-powered diagnostic or assistive tool for human readers.
6. Standalone Performance (Algorithm Only without Human-in-the-Loop Performance)
- Not applicable. This device is a physical medical device (stent), not an AI algorithm.
7. Type of Ground Truth Used
- Not applicable / Not mentioned. No clinical performance study requiring ground truth is described. The basis for approval is substantial equivalence to a predicate device.
8. Sample Size for the Training Set
- Not applicable / Not mentioned. This document does not describe a machine learning algorithm or a training set.
9. How the Ground Truth for the Training Set Was Established
- Not applicable / Not mentioned. This document does not describe a machine learning algorithm or a training set requiring ground truth.
Conclusion:
The provided 510(k) Summary pertains to a physical medical device (a biliary stent) and focuses on demonstrating "substantial equivalence" to a previously cleared product. It does not contain information about a dedicated performance study with specific acceptance criteria, test sets, ground truth establishment, or expert involvement as would be found in a clinical trial report for an AI/diagnostic device. The primary "proof" of meeting safety and effectiveness for this submission is its likeness to the predicate device.

Dear Ms. Brittle:
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.

§ 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.
