Device Description

The Smith & Nephew SUTUREFIX Ultra Suture Anchor is intended to provide secure . fixation of soft tissue to bone. The device consists of a soft suture anchor with an attached non-absorbable suture(s) preassembled onto an insertion device. The SUTUREFIX Ultra Suture Anchors are available pre-loaded with either one #2 suture or with two #1 sutures. This device is provided sterile, for single use only.

AI/ML Overview

Here’s a breakdown of the acceptance criteria and study information for the SUTUREFIX Ultra Suture Anchor, based on the provided text:

Important Note: The provided text is a 510(k) premarket notification summary. This type of submission generally focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed clinical efficacy studies against acceptance criteria like you'd find for novel therapies or AI-driven diagnostic tools. Therefore, much of the requested information (especially regarding AI, human readers, sample sizes for training/test sets, and expert details for ground truth) is not applicable or not present in this document. The document primarily discusses mechanical performance data.


Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Implied)Reported Device Performance
Insertion Strength MetMet performance specifications for insertion strength
Pull-out Strength MetMet performance specifications for pull-out strength
Substantial Equivalence to Predicate DevicesConsidered substantially equivalent to currently marketed predicate devices, raising no new issues of safety and efficacy.

Explanation: The document states, "Performance data demonstrates that the SUTUREFIX Ultra Suture Anchor has met performance specifications for insertion strength and pull-out strength and therefore, is considered substantially equivalent to the currently marketed predicate devices." This implies that the 'acceptance criteria' were the successful demonstration of adequate insertion and pull-out strength, and the ultimate acceptance criterion was deemed 'substantially equivalent' to the predicate devices.


Study Details

  1. Sample size used for the test set and the data provenance:

    • Sample Size: Not explicitly stated. The document refers to "Performance data" but does not quantify the number of devices or tests performed.
    • Data Provenance: Not specified, but generally, such biomechanical testing would be conducted in a laboratory setting (e.g., in-vitro or ex-vivo testing). No information on country of origin for the data is provided, nor whether it was retrospective or prospective in a clinical sense.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • Not Applicable. For a mechanical device like a suture anchor, ground truth is typically established through direct physical measurement and engineering standards, not through "expert consensus" in the medical diagnostic sense. There are no "experts" establishing a diagnostic ground truth.
  3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • Not Applicable. Adjudication methods like 2+1 or 3+1 are used in studies where human interpretation of medical images or data is involved to establish a consensus ground truth. This is a biomechanical performance study, not an interpretative one.
  4. 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 implant, not an AI-assisted diagnostic or imaging device. Therefore, no MRMC study, AI assistance, or human reader improvement data is relevant or provided.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Not Applicable. This is a physical medical device, not an algorithm or AI.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • Biomechanical Performance Metrics: Ground truth for this device would be based on empirically measured physical properties, such as the force required for insertion and the force required to pull out the anchor from a test material (e.g., bone surrogate or cadaveric bone). This is determined by engineering and biomechanical testing standards.
  7. The sample size for the training set:

    • Not Applicable. This is not an AI/ML device that requires a "training set."
  8. How the ground truth for the training set was established:

    • Not Applicable. As above, no training set for an AI/ML model.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
