Device Description

The device described in this 510(k) is a sterile, preloaded, disposable, absorbable suture anchor/inserter assembly designed to allow soft tissue repair to bone. The product is designed for single patient use only. The anchor is constructed of Polylactic Acid (PLA) and the Panacry)™ suture is a braided long term absorbable suture.

AI/ML Overview

This document describes the BioKnotless Anchor, a sterile, preloaded, disposable, absorbable suture anchor/inserter assembly designed for soft tissue repair to bone. The information provided outlines the safety and effectiveness summary as required for a 510(k) premarket notification.

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state quantitative acceptance criteria or a specific table detailing such criteria. However, it mentions the types of tests performed and the conclusion regarding substantial equivalence.

Acceptance Criteria (Implied)Reported Device Performance
Functional Integrity: Anchor pullout strength from bone."Anchor pullout from bone testing... were conducted on the device." Data "supported the substantial equivalence."
In Vitro Performance: Other in vitro mechanical characteristics."...and in vitro testing were conducted on the device." Data "supported the substantial equivalence."
Biocompatibility: Meet established biocompatibility standards."Biocompatibility testing (according to the FDA guidance document, ODE Blue Book Memorandum #G95-1, 1995, Use of International Standard ISO-10933, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing" were performed..." Data "supported the substantial equivalence."
Substantial Equivalence: To predicate devices (Mitek - Knotless Anchor and Mitek - Panalok™ Wedge Anchor)."Based on the Indications for Use, technological characteristics and safety and performance testing, the BioKnotless Anchor has been shown to be substantially equivalent to predicate devices..."

2. Sample sized used for the test set and the data provenance

The document does not specify the sample sizes for the functional and integrity bench testing or the biocompatibility testing. The data provenance is not explicitly stated beyond the mention of "bench testing" and "in vitro testing," which generally implies laboratory-controlled studies. There is no information regarding country of origin or whether the data was retrospective or prospective in a clinical sense, as these were bench and in vitro tests, not human studies.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This section is not applicable. The study involved bench testing and in vitro performance, not expert-derived ground truth as would be relevant for diagnostic AI/medical imaging devices. The "ground truth" here would be the physical properties and performance measured directly by scientific methods and instrumentation.

4. Adjudication method for the test set

This section is not applicable for the type of testing described (bench and in vitro performance). Adjudication methods like 2+1 or 3+1 are used in clinical trials or studies involving expert interpretation, which is not the case here.

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

No, an MRMC comparative effectiveness study was not done. This device is a physical surgical anchor, not an AI or diagnostic imaging device that involves human readers or AI assistance.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

This section is not applicable. The BioKnotless Anchor is a physical medical device, not an algorithm.

7. The type of ground truth used

The "ground truth" for this device's evaluation was based on objective, measurable physical and chemical properties and performance characteristics. This includes:

  • Mechanical Strength: Measured through tests like anchor pullout from bone.
  • In Vitro Performance: Other measurable mechanical properties under laboratory conditions.
  • Biocompatibility: Assessment against established international standards (ISO-10933), likely involving laboratory assays and material characterization.

These are not "expert consensus," "pathology," or "outcomes data" in the traditional sense, but rather direct measurements of the device's physical and biological interactions.

8. The sample size for the training set

This section is not applicable. There is no "training set" in the context of evaluating a physical medical device like a surgical anchor. Training sets are relevant for machine learning algorithms.

9. How the ground truth for the training set was established

This section is not applicable, as there is no training set for this type of device evaluation.

Dear Ms.LeGraw:

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. 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 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.

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.

Identification. An absorbable poly(glycolide/l-lactide) surgical suture (PGL suture) is an absorbable sterile, flexible strand as prepared and synthesized from homopolymers of glycolide and copolymers made from 90 percent glycolide and 10 percent l-lactide, and is indicated for use in soft tissue approximation. A PGL suture meets United States Pharmacopeia (U.S.P.) requirements as described in the U.S.P. “Monograph for Absorbable Surgical Sutures;” it may be monofilament or multifilament (braided) in form; it may be uncoated or coated; and it may be undyed or dyed with an FDA-approved color additive. Also, the suture may be provided with or without a standard needle attached.(b)
Classification. Class II (special controls). The special control for this device is FDA's “Class II Special Controls Guidance Document: Surgical Sutures; Guidance for Industry and FDA.” See § 878.1(e) for the availability of this guidance document.
