The document describes a physical implant (cage) and associated instruments for spinal fusion. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is indicated for facilitating interbody fusion in the lumbar spine for patients with degenerative disc disease, which is a therapeutic purpose.
No
The device is an implant for spinal fusion and does not perform any diagnostic functions. Its purpose is therapeutic.
No
The device description clearly states it is a cage made of titanium alloy, which is a physical implant, 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 describes a surgical implant for spinal fusion. It is used in vivo (within the body) to facilitate bone growth and stabilize the spine.
- Device Description: The device is a physical implant (a cage) made of titanium alloy, designed to be surgically placed between vertebrae.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.
IVD devices are used outside the body to analyze biological samples. This device is an implant used inside the body.

Intended Use / Indications for Use
The KG2 implant is indicated for transforaminal and posterior interbody fusion of the spine in skeletally mature patients with degenerative disc disease (DDD) and up to Grade 1 spondylolisthesis of the lumbar spine at one level or two contiguous levels. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The KG2 implant is used to facilitate interbody fusion in the lumbar spine from L2 to S1 using autogenous and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft to facilitate fusion. The interbody fusion devices are intended to be used with FDA-cleared supplemental fixation designed for the implanted level. Patients should have at least six months of non-operative treatment with an interbody fusion device.

Device Description
The Kleiner KG2 is a cage intended for lumbar intervertebral fusion (PLIF/TLIF approach). The design contains both solid and porous structures formed as a diamond mesh, and it contains a bone grafting hole. The cage is additively manufactured from titanium alloy. The KG2 cage may be used with coverplate.
The sterile Kleiner KG2 implant comes pre-assembled on the inserter and includes pre-packaged sterile, single-use instrumentation for primary insertion, graft passing, and cover plate insertion. A reusable set of instruments are included for disc preparation, trial sizing, and repositioning/removal.

§ 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.

Dear Martjin Heikens:
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 (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 located 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.

8. Conclusion of Substantial Equivalence
The subject Kleiner KG2 System has the same intended use/indications for use, the same or similar technology, comparable principles of operation, same range of size parameters, and same materials as the identified predicate systems: Ossous Aries-TC and Aries-TS (K181347), Stryker (K2M) Mojave (K193203), and NuVasive MLX (K173025). The Kleiner KG2 System does not present any new issues of safety or effectiveness as compared to the predicate systems. Performance testing demonstrates the subject implants are as stronger compared to previously cleared devices with similar indications. Therefore, the Kleiner KG2 System is substantially equivalent to the identified predicate systems.
