• Attributes: Therapeutic

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; Knee: MCL, LCL, Iliotibial Band Tenodesis; Foot/Ankle: Lateral Stabilization, Medial Stabilization.

Device Story

The GRYPHON™ Flex Knotless Anchor is a two-piece orthopedic fixation system consisting of a permanent anchor and a disposable inserter. The device is used by surgeons in clinical settings to reattach soft tissue to bone. The anchor is preloaded on the inserter; a Nitinol distal tip retains the suture and anchor during mallet-driven insertion into bone. The inserter is available in straight or curved configurations to improve maneuverability within the joint space. By providing a knotless fixation method, the device simplifies soft tissue repair procedures, potentially reducing surgical time and improving outcomes in shoulder, hip, knee, and foot/ankle repairs.

Clinical Evidence

Bench testing only. Performance evaluation included in-vitro fixation strength at 0, 6, 12, 13, and 26 weeks, insertion torque, torque to failure, and cyclic/post-cyclic fixation at time zero. Biological safety evaluated per ISO 10993-1; sterilization validated per ANSI/AAMI/ISO 11135:2014; non-pyrogenicity confirmed per ANSI/AAMI ST-72:2011.

Technological Characteristics

2.7mm knotless suture anchor. Materials: PEEK or Biocomposite (Polylactic Acid and Tricalcium Phosphate). Two-piece design with permanent anchor and disposable inserter (straight or curved). Sterilization: Ethylene Oxide (EO) per ANSI/AAMI/ISO 11135:2014. Single-use.

Indications for Use

Indicated for reattachment of soft tissue to bone in shoulder (Bankart, SLAP, capsular shift/reconstruction, superior capsule reconstruction), hip (acetabular labral repair), knee (MCL, LCL, iliotibial band tenodesis), and foot/ankle (lateral/medial stabilization) procedures.

Regulatory Classification

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.

# 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).

| Ethylene Oxide Sterilization was validated according to ANSI/AAMI/ISO 11135: 2014 to a<br>SAL of 1 x 10-6. | |
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| EO residuals were tested per AAMI/ANSI/ISO 10993-7:2008. | |
| Biological safety was evaluated according to ISO 10993-1 for devices having direct patient<br>contact, inclusive of raw materials of components, manufacturing processes, sterilization, and primary<br>packaging materials. | |
| The proposed device has been determined to be non-pyrogenic per the requirements set forth<br>in ANSI/AAMI ST-72:2011, United States Pharmacopeia (USP), and European<br>Pharmacopeia (EP) using the bacterial endotoxin testing (BET) method. | |
| Safety and<br>Performance | Results of non-clinical performance testing have demonstrated that the proposed devices are<br>suitable for their intended use. |
| | Based on similarities in the indications for use, technological characteristics, and<br>performance testing in comparison to the predicate devices, the proposed GRYPHON Flex<br>Knotless PEEK and BIOCOMPOSITE Anchors have demonstrated that they are substantially<br>equivalent to the predicate device under the Federal Food, Drug and Cosmetic Act. |
