Intended Use

The GRYPHON™ Flex Knotless Anchor is indicated for use for reattachment of soft tissue to bone for the following procedures:
Shoulder: Bankart Repair, SLAP Lesion Repair, Capsular Shift or Capsulolabral Reconstruction, Superior Capsule Reconstruction (Glenoid Only)
Hip: Acetabular Labral Repair

Foot/Ankle: Lateral Stabilization, Medial Stabilization

Device Description

The proposed GRYPHON™ Flex Knotless PEEK and BIOCOMPOSITE Anchors is a line extension to the currently marketed GRYPHON Anchor family. The proposed product is a knotless anchor intended for fixation of soft tissue to bone in various soft tissue repair procedures. In its finished good configuration, the proposed device is a two-piece design; comprised of a permanent implant (anchor) component and a disposable (inserter) component. The 2.7mm anchor implant is preloaded on the inserter and a Nitinol distal tip retains the suture and the anchor while the device is malleted into the bone. The design offers surgeons maneuverability within the joint space. The disposable inserter will be offered in two design configurations, straight or curved to accommodate varying anatomies.
The proposed GRYPHON Flex Knotless PEEK and BIOCOMPOSITE Anchors will be available in a 2.7 mm size, molded from either Polyetheretherketone (PEEK) material or Absorbable Biocryl Biocomposite ((Polylactic Acid (PLA) and Tricalcium Phosphate (TCP)) material.
Both the GRYPHON Flex Knotless PEEK and BIOCOMPOSITE Anchors are provided sterile via Ethylene Oxide (EO) sterilization and are for single use only.

AI/ML Overview

The provided document is a 510(k) clearance letter from the FDA for a medical device called the "GRYPHON™ Flex Knotless PEEK Anchor" and "GRYPHON™ Flex Knotless Biocomposite Anchor."

This document does not describe a study that uses AI or machine learning. It describes the non-clinical verification activities performed for a physical medical device (suture anchor), focusing on its mechanical properties, sterilization, and biocompatibility. Therefore, it does not include the information requested regarding acceptance criteria and studies for AI/ML device performance, such as sample size for test sets, data provenance, expert adjudication, MRMC studies, standalone performance, ground truth establishment, or training set details.

The acceptance criteria mentioned in the document relate to the physical and biological performance of the anchor, not to the performance of a diagnostic or predictive algorithm.

Therefore, I cannot fulfill your request for information regarding acceptance criteria and studies that prove an AI/ML device meets those criteria based on the provided text, as the text describes a physical medical device, not an AI/ML system.

Dear Elizabeth Messana:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review. the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).

§ 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.
