No.
The device is described as a fixation device used in orthopedic surgical procedures to fix bone or soft tissue to bone, specifically for ACL/PCL repair and reconstruction. It is not intended to treat, mitigate, or cure a disease or condition itself, but rather to aid in the mechanical repair of tissue.

No

No

The device description clearly states it is a permanently implantable Polyether Ether Ketone (PEEK) cortical tibial suspension fixation device, which is a physical hardware component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the device is for "fixation of bone or soft tissue to bone" in surgical procedures (specifically knee ligament repair and reconstruction). This is a therapeutic and structural function within the body.
  • Device Description: The description confirms it's a "permanently implantable Polyether Ether Ketone (PEEK) cortical tibial suspension fixation device." This is a physical implant used to provide mechanical support.
  • Lack of IVD Characteristics: An IVD device is used in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The provided information does not mention any such use or interaction with bodily specimens for diagnostic purposes.

The device described is a surgical implant used for mechanical fixation during orthopedic procedures, which falls under the category of medical devices, but not specifically In Vitro Diagnostic devices.

Substantial Analysis

SE Analysis 1 Button Material

The primary predicate Arthrex ACL TightRope® button is made of Titanium whereas the reference predicate ANCHORMAN Tibial Ligament Fixation Device material of construction is PEEK. The subject device material of construct for button is PEEK (Polyether Ether Ketone) which is equivalent to the reference predicate.

The reference predicate has already proven safety and efficacy of PEEK material in reference to the titanium based button in their K170388 submission.

PEEK is chemically inert and insoluble, has a modulus of elasticity closer to human cortical bone. Hence, PEEK represents a stable and biocompatible material that may address the issues that are present with titanium screws, such as graft damage because of material hardness and interference with imaging. PEEK has poor osseointegration. PEEK has excellent bio-compatibility and biological stability, and is a very favorable implant material.

Also, the bio-compatibility testing of the subject devices has been performed to substantiate the biocompatible nature of the subject device. The summary of the biocompatibility testing performed has been shown in the below table.

Biocompatibility TestResult
Skin Sensitization (Guinea Pig
Maximization Test)Non-Sensitizer
Intracutaneous Reactivity TestNon-Reactive
Material Mediated
PyrogenicityNon-Pyrogenic
Acute Systemic Toxicity TestDid not Induce any Systemic
Toxicity
In vitro Cytotoxicity Test:
Elution MethodNon-Cytotoxic
Bone Implantation Studies
(PEEK Rods)Minimal or No Reaction
Bone Implantation Studies
(UHMWPE Suture)Minimal or No Reaction
Intra muscular Implant
(PEEK)Minimal or No Reaction

In reference to the above mentioned evidences the difference in the material of construction between the primary predicate and the subject device do not raise any new questions of safety and effectiveness.

To the right of the word, there is a graphic consisting of two overlapping circles, one blue and one orange, with a white plus sign in the intersection.

SE Analysis 2 Loop Material

The adjustable loop material construct of the primary predicate device (Arthrex ACL TightRope®) and the adjustable loop of the T-button®A - Closed button (subject device) is UHMWPE; which are similar.

However, the adjustable loop of the T-button® S - Open button (Subject Device) has Loop and Suture Button. The material of construct of loop is UHMWPE (UHMWPE 100.0%) and Suture Button has a material of construct of Non-absorbable, UHMWPE (UHMWPE ≥ 88.0%) + Additive: Loctite 4014 (≤12.0% in the Suture Button)).

The suture button in the adjustable loop tends to hold the loop, the pull out strength of the suture button in the bench testing has been performed and evaluated, the results are perceptible to define the strength of suture button to hold the loop.

The above mentioned addition of Suture Button in the adjustable loop of the T-button® S - Open button (Subject Device) has no impact on the safety and efficacy of the product.

The Arthrex ACL TightRope® and the ANCHORMAN Tibial Ligament Fixation Device offers adjustable cortical fixation for cruciate ligament reconstruction. The ACL TightRope® RT comes with the regular button (13mm (L) x 3.3mm (W) x1.5mm (H)) preloaded with adjustable loop and double loaded passing sutures whereas the subject device comes with Open and Closed Button having dimensions (16mm(dia)x 7.5mm (H)). The Closed button is preloaded with UHMWPE adjustable loop and in Open Button the adjustable loop is non preloaded.

The Pull Out Test and the Cyclical Load tests were performed for the primary predicate, reference predicate and the subject device and the results were compared and found equipotent in terms of safety and efficacy irrespective to the material of construction and design.

SE Analysis 4 Specifications and Dimensions

During the bench testing of subject device, it was observed that the changes in dimensions are not leading to any kind of new risks with the performance of subject device, and the acceptance criteria was met in each of the performance tests. By considering the performance data of the subject device, it is evident that the changes in dimensions are not causing and or does not affect the safety and efficacy of the product when comparing it with Predicate device.
