Weck® Ligating Clips are intended for use in procedures involving vessels or anatomic structures for which the surgeon determines ligating clips are the best choice. Surgeons should select the size, type and material of the clip based upon their experience, judgment and needs.

Device Description

Weck® Metal Ligating Clips are single-use, non-absorbable, non-active implantable devices designed for use in general surgical procedures that require vessel or tissue ligation. Each product line possesses a unique design necessary for compatibility with its appropriate Weck® ligating clip applier. The clips are available in a range of sizes, allowing the end user to ligate a wide range of vessels and tissue structures. Weck® Metal Ligating Clips are manufactured from medical grade titanium, tantalum or stainless steel alloys and are provided prepackaged in color-coded cartridges, which are provided as single-use, sterile devices.

Accessories to the Weck® Metal Ligating Clips include manual clip appliers and removers for use in both general open and endoscopic procedures. Both the appliers and removers are multiple use, non-sterile devices that require cleaning and sterilization prior to each use.

AI/ML Overview

The Weck® Metal Ligating Clips are non-absorbable, non-active implantable devices used for vessel or tissue ligation in general surgical procedures. The clips are made from medical-grade titanium, tantalum, or stainless steel alloys.

Here's an analysis of the provided information regarding acceptance criteria and the supporting study:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria	Reported Device Performance
"MR Conditional" Claim	"MR Conditional" for environments of 3-Tesla or less
Safety and Compatibility in MR Environment	Demonstrated safe use in 3-Tesla or less MR environments
Equivalence to Predicate Devices	Substantially equivalent in performance to K982313 and K841547
No New Safety/Effectiveness Issues	Modifications do not introduce new issues of safety and effectiveness

2. Sample Size and Data Provenance

Test Set Sample Size: Not explicitly stated. The document mentions "Non-clinical performance testing" was conducted, but specific sample sizes for this testing are not provided.
Data Provenance: The studies were non-clinical performance testing conducted by the manufacturer, Teleflex Medical, Incorporated, to support a 510(k) submission to the FDA in the USA. This is considered prospective, manufacturer-conducted testing for regulatory approval.

3. Number of Experts and Qualifications for Ground Truth

Not applicable. The ground truth for this device (MR Conditional claim, material compliance, and substantial equivalence) was established through non-clinical performance testing and comparison to existing predicate devices, rather than expert interpretation of medical images or data.

4. Adjudication Method

Not applicable. Adjudication methods like 2+1 or 3+1 are typically used in studies involving human interpretation of data where consensus among experts is needed. This submission relies on objective engineering and material testing.

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

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for evaluating diagnostic aids or AI systems that assist human readers in tasks like image interpretation, and the Weck® Metal Ligating Clips are a physical implantable device.

6. Standalone Performance Study

Yes, a standalone study was done in the sense that the device's "MR Conditional" performance was tested independently of human intervention. The "Non-clinical performance testing" was conducted on the device itself to determine its behavior in an MR environment. However, this is not "algorithm only" performance as often seen in AI/software substantial equivalence discussions, but rather direct device performance testing.

7. Type of Ground Truth Used

Engineering and Material Standards: The ground truth for the "MR Conditional" claim was based on established engineering standards (ASTM F2503-08) and FDA guidance for medical devices in MR environments.
Comparison to Predicate Devices: The ground truth for overall safety and effectiveness was established by demonstrating substantial equivalence to previously cleared predicate devices (K982313 and K841547), implying that if the new device performs similarly to devices already deemed safe and effective, it is also safe and effective.
Biological Compatibility: Patient-contacting materials compliance with ISO10993-1 provides ground truth for biocompatibility.

8. Sample Size for the Training Set

Not applicable. This device is not an AI/ML algorithm that requires a training set. The performance data is based on physical testing of the device itself.

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

Not applicable, as no training set was used.

F. Indications for Use

G. Contraindications

Weck® Ligating Clips are not intended for use as a contraceptive tubal occlusion device.

Weck® Ligating Clips are contraindicated for use in ligating the renal artery during laparoscopic donor nephrectomies.

H. Environmental Conditions

Weck® Metal Ligating Clips are "MR Conditional" up to and including 3-Tesla MR environments.

I. Substantial Equivalence

The proposed Weck® Metal Ligating Clips are substantially equivalent to the predicate devices:

Predicate Device	Manufacturer	510(k) No.	Date Cleared
Horizon™ Ligating Clip	Teleflex Medical(Weck)	K982313	08/10/1998
Hemoclip® Traditional LigatingClip	Teleflex Medical(Weck)	K841547	08/14/1984

J. Comparison To Predicate Devices

The proposed Weck® Metal Ligating Clips have the same technology and functional characteristics as the predicate system. The proposed modifications include the addition of magnetic resonance (MR Conditional) claims, addition of a contraindication for renal donor nephrectomy, addition of cleaning and sterilization instructions for reusable instrumentation, two line extensions, a change in packaging materials, and a change in the sterilization method of the Horizon™ Ligating Clips.

K. Materials

All patient contacting materials are in compliance with ISO10993-1.

L. Technological Characteristics

A comparison of the technological characteristics of the proposed Weck® Metal Ligating Clips and the predicates has been performed. The results of this comparison demonstrate that the Weck® Metal Ligating Clips are equivalent to the marketed predicate devices.
