Intended Use

The Influence Clip System is indicated for permanent securing of two strands of surgical suture for soft tissue approximation in open or laparoscopic surgical procedures.

Device Description

The Influence Clip System has two components, a suture clip and an applier. To fixate sutures, the stainless steel clip is inserted into the applier. Two strands of suture are threaded through the clip and the applier inserted into the trocar (if a laparoscopic procedure is performed). The applier's handle is then tightly squeezed which causes a rod within the applier's shaft to crimp the clip around the sutures. The sutures' ends are cut close to the clip (alternative version of applier with suture cutter may be used). The system is provided sterile and the applier is disposable, for single patient use.

AI/ML Overview

The provided document is a 510(k) summary for the Influence Clip System, which focuses on the regulatory clearance process for a medical device. It does not contain a study that proves the device meets specific acceptance criteria in terms of performance metrics like accuracy, sensitivity, or specificity. Instead, the document states that the device's safety and effectiveness were demonstrated through bench testing and that its performance is substantially equivalent to a previously cleared 510(k) device.

Therefore, it is not possible to fill out all the requested information concerning acceptance criteria, study details, ground truth establishment, sample sizes, or expert adjudication for a performance study from this document.

However, based on the information provided, we can infer the primary "acceptance criterion" from a regulatory perspective:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria (Inferred from regulatory context)Reported Device Performance
Safety (Biocompatibility, lack of adverse effects)All materials commonly used or proven biocompatible.
Effectiveness (Ability to permanently secure sutures for soft tissue approximation)Bench testing demonstrated safety and effectiveness.
Substantial Equivalence to Predicate Devices (Safety and effectiveness profile)Performance substantially equivalent to a 510(k)-cleared device.

Missing Information (Not available in the provided text):

  • 2. Sample sizes used for the test set and the data provenance: Not mentioned. The testing was "bench testing," meaning lab-based, not clinical data involving patients.
  • 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. This refers to expert review of clinical cases, which was not the nature of the testing described.
  • 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable, as no clinical test set requiring adjudication by experts is described.
  • 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: Not applicable. This device is a surgical clip, not an AI-powered diagnostic tool.
  • 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithm. Bench testing would assess the device's physical performance.
  • 7. The type of ground truth used: For a medical device like this, the "ground truth" for bench testing would likely be based on engineering specifications and physical measurements (e.g., tensile strength tests, slip resistance tests for the clip on sutures), rather than expert consensus on clinical findings or pathological diagnoses. The document vaguely states "bench testing has demonstrated that the device is safe and effective."
  • 8. The sample size for the training set: Not applicable, as this is a physical device, not an AI algorithm requiring a training set.
  • 9. How the ground truth for the training set was established: Not applicable.

In summary: The provided document is a regulatory submission focused on substantial equivalence based on bench testing. It does not describe a clinical study with detailed performance metrics, ground truth establishment, or human reader involvement as would be typical for an AI/diagnostic device.

Dear Dr. Bick:

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 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. 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.

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 requirement, as set forth in the Quality System Regulation (OS) 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.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
