The Cordis PALMAZ® XL Transhepatic Biliary Stents are intended for use in the palliation of malignant neoplasms in the biliary tree.
The PALMAZ® XL Transhepatic Biliary Stent is a balloon-expandable, laser cut stent made from 316L stainless steel tubing. The stent is supplied in two nominal lengths: 40 mm, and 50 mm. The stent is designed to expand to 10mm diameter. The PALMAZ® XL Transhepatic Biliary Stent is sold unmounted for use with the Cordis POWERFLEX™ PLUS Percutaneous Transluminal Angioplasty (PTA) balloon catheter.
The provided text does not contain detailed acceptance criteria or a study proving the device meets specific performance criteria beyond substantial equivalence. The document is a 510(k) submission summary for the Cordis PALMAZ® XL Transhepatic Biliary Stent, focusing on demonstrating substantial equivalence to a predicate device.
Here's a breakdown of the information available based on the provided text, addressing your points where possible:
1. Table of Acceptance Criteria and Reported Device Performance:
The document does not specify quantitative acceptance criteria. Instead, it asserts "substantial equivalence" to a predicate device.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Substantial Equivalence to predicate device (Cordis PALMAZ® Balloon Expandable Transhepatic Biliary Stents) | Substantial equivalence confirmed through pre-clinical testing. (Specific performance metrics are not detailed in this summary.) |
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: Not specified. The document only mentions "pre-clinical testing" for confirming substantial equivalence, but details on the number of devices or scenarios tested are absent.
- Data Provenance: Not specified (e.g., country of origin). The testing is described as "pre-clinical," which typically implies laboratory or animal studies, not human clinical data in this context. The document does not indicate if it was retrospective or prospective.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications:
Not applicable. The document describes pre-clinical testing for substantial equivalence, which would likely involve engineering and material scientists, rather than medical experts establishing ground truth in a clinical trial setting.
4. Adjudication Method for the Test Set:
Not applicable. There is no mention of an adjudication process for a test set in the context of expert review.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
A MRMC comparative effectiveness study was not mentioned in the document. The focus is on demonstrating substantial equivalence through pre-clinical testing, not on comparing human reader performance with and without AI assistance. The device itself is a physical stent, not an AI-powered diagnostic tool.
6. Standalone (Algorithm Only) Performance Study:
Not applicable. The device is a physical medical device (biliary stent), not an algorithm or AI system. Therefore, standalone algorithm performance is not relevant.
7. Type of Ground Truth Used:
The concept of "ground truth" as typically used for diagnostic devices (e.g., pathology, outcomes data) is not explicitly detailed here. For pre-clinical testing of a physical device like a stent, "ground truth" would relate to engineering specifications, material properties, mechanical performance (e.g., expansion, radial strength, fatigue resistance), and biocompatibility, likely established through laboratory measurements and established testing methodologies. The document states "All materials used... are biocompatible," which would imply testing against established biocompatibility standards.
8. Sample Size for the Training Set:
Not applicable. Since this is a physical medical device and not an AI/ML algorithm, there is no "training set."
9. How the Ground Truth for the Training Set Was Established:
Not applicable, for the same reason as point 8.

Re: K993091 Cordis PALMAZ® XL Transhepatic Biliary Stent Regulatory Class: II 21 CFR 876.5010 Product Code: 78 FGE Dated: October 14, 1999 Received: October 15, 1999
Dear Ms. MacTavish:
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 In incels in the start comments, 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, includes proximity to the trade name, of a similar point size, and other proniot

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market a This letter will allow you to begin marketing your device as described in your 510(k) premarket notification if the limitation statement above is added to your labeling, as described.
Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.
