No
The document describes a physical implant (intervertebral body fusion device) and its mechanical properties and testing. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is an intervertebral body fusion device used to treat degenerative disc disease and degenerative scoliosis, which are considered medical conditions, and its purpose is to aid in lumbar spinal fixation and fusion, thus providing a therapeutic effect.
No
The provided text clearly states that the "Stryker Spine Tritanium® TL cage is an intervertebral body fusion device." It is described as an implant used for spinal fixation and fusion, not for diagnosing medical conditions. The device description and performance studies focus on its mechanical properties and suitability as an implant.
No
The device description clearly states it is a "curved implant" constructed from "Titanium alloy" and is provided "sterile," indicating it is a physical hardware device, not software.
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 an intervertebral body fusion device used in surgical procedures to aid in spinal fusion. It is implanted into the body.
- Device Description: The description details a physical implant made of titanium alloy, designed to be inserted into the spine.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is an in vivo (inside the body) implant.

Intended Use / Indications for Use
The Stryker Spine Tritanium® TL cage is an intervertebral body fusion device indicated for use with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft when used as an adjunct to fusion in patients with degenerative disc disease (DDD) at one level or two contiguous levels from L2 to S1.
DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The DDD patients may also have up to Grade I spondylolisthesis at the involved level(s). These patients should be skeletally mature and have six months of nonoperative therapy.
Additionally, the Tritanium TL Cage can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis.
The Tritanium TL Cage is to be implanted via a posterior approach.
The Tritanium TL Cage is intended to be used with supplemental spinal fixation systems that have been cleared for use in the lumbosacral spine.

Device Description
The purpose of this submission is to introduce a curved posterior lumbar cage intended for use as an aid in lumbar spinal fixation.
The Tritanium TL Intervertebral Body Fusion Cage is intended for use as an aid in lumbar spinal fixation. The cage is a curved implant that consists of a unique configuration of both solid and porous structures that are simultaneously built using Laser Rapid Manufacturing (LRM) method applying Stryker's proprietary Tritanium® In-Growth Technology. The cage is offered in a variety of lengths, heights and lordotic angles to adapt to a variety of patient anatomies. It has serrations on the superior and inferior surfaces designed for multidirectional fixation and to maximize surface area for endplate contact with the implant. The implants have a smooth, tapered leading edge to facilitate cage insertion into the intervertebral space. The implants have a central column spanning endplate to endplate for graft containment and to aid in fusion throughout the interbody cage.
The implant is designed to be used with supplemental fixation cleared for use in the lumbosacral spine.
The Tritanium TL cages are constructed from Titanium alloy: Ti-6Al-4V (ASTM F1472-08) and are provided sterile.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Testing in compliance with:
FDA's June 12, 2007 "Class II Special Controls Guidance Document: Intervertebral Body Fusion Device" was performed for the subject Tritanium TL Cages and demonstrated substantially equivalent performance to the identified predicate devices. The following mechanical tests were performed:
Static and Dynamic Compression (per ASTM F2077-14)
Static and Dynamic Compression Shear (per ASTM F2077-14)
Static and Dynamic Torsion (per ASTM F2077-14)
Expulsion (per ASTM F04-25-02-02 Draft)
Subsidence (per ASTM F2267-04(2011))
Wear Debris Assessment, and Impaction
Characterization of the Physical, Chemistry and Mechanical properties of the subject Tritanium TL Curved Posterior Lumbar Cage was established through Tritanium C Anterior Cervical Cage material testing which demonstrated that the porous surface design of the cage met at minimum the requirements outlined in the:
FDA guidance documents: "Guidance Document for testing orthopedic implants with modified metallic surfaces apposing bone or bone cement [April 28, 1994]", "Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses [January 16, 2003]", and draft guidance for "Technical considerations for Additive Manufactured Devices [May 10, 2016]"

Bacterial endotoxin testing (BET) as specified in ANSI/AAMI ST72:2011 is used for pyrogenicity testing to achieve the Endotoxin limit of
§ 888.3080 Intervertebral body fusion device.
(a)
Identification. An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.(b)
Classification. (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
