Intended Use

The MITEK TIGHT-N™ Tendon Docking Anchor is indicated for use for reattachment of soft tissue to bone for the following procedures: Shoulder: Biceps tenodesis Knee: Medial patellofemoral ligament repair/reconstruction (MPFL), posterior oblique ligament repair (POL), medial collateral ligament (MCL) repair, lateral ligament (LCL) repair, anterolateral ligament (ALL) reconstruction, Iliotibial (IT) Band Tenodesis

Device Story

The MITEK TIGHT-N™ Tendon Docking Anchor is a sterile, single-use implant designed for reattaching soft tissue to bone. It is provided preloaded on a disposable inserter shaft with a handle, secured by a stay suture. The device is available in 5.5 mm, 7.0 mm, and 8.5 mm sizes. During surgery, the surgeon threads the suture tails of a pre-stitched soft tissue graft through the anchor; the anchor is then inserted into the bone to secure the graft. Used in orthopedic surgical settings, the device provides mechanical fixation to facilitate tissue healing. It benefits patients by restoring soft tissue-to-bone attachment in ligament and tendon repair procedures.

Clinical Evidence

Bench testing only. Verification activities included biocompatibility, shelf-life, pyrogenicity, and endotoxin testing. Performance testing assessed fixation strength and fatigue strength. Sterilization validated per ANSI/AAMI/ISO 11135:2014; EO residuals tested per AAMI/ANSI/ISO 10993-7:2008; non-pyrogenicity confirmed per ANSI/AAMI ST-72:2011.

Technological Characteristics

Material: PEEK (Polyetheretherketone). Design: Suspensory push-in anchor. Sizes: 5.5 mm, 7.0 mm, 8.5 mm. Sterilization: Ethylene Oxide (EO) per ANSI/AAMI/ISO 11135:2014. Single-use. No software or electronic components.

Indications for Use

Indicated for reattachment of soft tissue to bone in shoulder (biceps tenodesis) and knee (MPFL, POL, MCL, LCL, ALL reconstruction, IT Band tenodesis) 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.

Predicate Devices

• Arthrex Biocomposite 3.9mm SwiveLock Anchor (K201749)

| Name of<br>Medical Device | Proprietary Name: MITEK TIGHT-NT™ Tendon Docking Anchor (also<br>referred to as TIGHT-NT™ Anchor)<br><br>Classification Name:<br>Fastener, Fixation, Nondegradable, Soft Tissue<br><br>Product Code: MBI<br>Common Name: Suture Anchor | |
| Substantial<br>Equivalence | The MITEK TIGHT-NT™ Tendon Docking Anchor is substantially<br>equivalent to:<br>• K201749 Arthrex Biocomposite 3.9mm SwiveLock Anchor | |
| Device<br>Classification | The MITEK TIGHT-NTM Tendon Docking Anchor is classified as:<br>Fastener, Fixation, Nondegradable, Soft Tissue, classified as Class II,<br>product code MBI, regulated under 21 CFR 888.3040. | |
| Device Panel | Orthopedic Devices | |
| Device<br>Description | The MITEK TIGHT-NTM Tendon Docking Anchor is designed to<br>reattach soft tissue to bone when used in conjunction with suture<br>(provided separately). The anchor is preloaded on a disposable inserter<br>shaft with handle, held in place by a non-absorbable "stay suture". The<br>proposed anchor will be offered in three sizes: 5.5 mm, 7.0 mm, and 8.5<br>mm and is molded from PEEK (Polyetheretherketone) material. The<br>proposed anchor is provided sterile via Ethylene Oxide (EO)<br>sterilization and is for single use only. | |
| Technological<br>Characteristics | The anchor design, principal of operation and intended use on MITEK<br>TIGHT-NTM Tendon Docking Anchor are similar when compared to the<br>predicate Arthrex 3.9mm SwiveLock Anchor (K201749). Both devices<br>are implantable anchors used to secure soft tissue to bone. Suture tails<br>of a pre-stitched soft tissue graft (suture provided separately) are<br>threaded through the anchors, thus securing the graft to the anchor.<br><br>The proposed MITEK TIGHT-NTM Tendon Docking Anchor is<br>designed as a suspensory push-in anchor, while the predicate<br>SwiveLock is designed as an interference thread-in anchor. While there<br>exists differences in the means of insertion style (thread-in vs. push in)<br>and mechanism of tissue retention, the proposed and predicate devices<br>are ultimately securing soft tissue to bone to achieve the device's<br>therapeutic benefit.<br><br>Both predicate and proposed devices are provided with sutures<br>facilitating placement of the anchor (stay sutures for both the proposed<br>and the predicate device and an additional axillary suture for the<br>proposed MITEK TIGHT-NTM Tendon Docking Anchor).<br><br>The proposed anchor is constructed from PEEK material, the predicate<br>Arthrex SwiveLock is composed of both PEEK and PLLA/βTCP<br>materials. The PEEK material, of the proposed anchor implant, is<br>identical to the PEEK material of existing Mitek implantable anchors –<br>Versalok Anchors (K100532)<br><br>Any differences between the proposed device and the predicate are<br>considered non-significant and do not raise different questions of safety<br>or effectiveness, supported by testing. | |
| Indications for<br>Use | The MITEK TIGHT-NTM Tendon Docking Anchor is indicated for use<br>for reattachment of soft tissue to bone for the following procedures:<br>Shoulder: Biceps tenodesis Knee: Medial patellofemoral ligament repair/reconstruction<br>(MPFL), posterior oblique ligament repair (POL), medial collateral<br>ligament (MCL) repair, lateral collateral ligament (LCL) repair,<br>anterolateral ligament (ALL) reconstruction, Iliotibial (IT) Band<br>Tenodesis | |
| Non-clinical<br>Testing | Verification activities were performed on the proposed device and / or<br>its predicates. Biocompatibility, shelf-life, pyrogenicity, endotoxin and<br>performance testing conducted on representative products was presented<br>to support determination of equivalence. Performance testing included<br>assessment of fixation strength and fatigue strength. | |
| | Ethylene Oxide Sterilization was validated according to<br>ANSI/AAMI/ISO 11135: 2014 to a SAL of 1 x 10-6. | |
| | EO residuals were tested per AAMI/ANSI/ISO 10993-7:2008 | |
| | The proposed device has been determined to be non-pyrogenic per the<br>requirements set forth in ANSI/AAMI ST-72:2011, United States<br>Pharmacopeia (USP), and European Pharmacopeia (EP) using the<br>bacterial endotoxin testing (BET) method. | |
| Safety and<br>Performance | Results of performance testing have demonstrated that the proposed<br>devices are suitable for their intended use. | |
| | Based on similarities in the intended use, technological characteristics,<br>and performance in comparison to the predicate devices, the proposed<br>MITEK TIGHT-NTM Tendon Docking Anchor has shown to be<br>substantially equivalent to the predicate device under the Federal Food,<br>Drug and Cosmetic Act. | |
