The summary describes a physical implant device and its mechanical properties. There is no mention of software, algorithms, or any technology that would typically incorporate AI/ML. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
Yes.
The device is intended for anterior interbody fusion to treat conditions like cervical disc degeneration and spinal instability, aiming to alleviate radiculopathy, myelopathy, and pain, which are therapeutic goals.
No
The device is an interbody fusion system designed to treat cervical disc degeneration and spinal instability by facilitating fusion and providing stabilization. It is a therapeutic device, not a diagnostic one. The mention of imaging studies (radiographs, CT, MRI) refers to how the condition is confirmed, not to the device itself performing diagnostics.
No
The device description explicitly states that the ZSFab Cervical Interbody System includes "additively manufactured interbody fusion devices for cervical implantation," which are physical implants, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens from the human body. The ZSFab Cervical Interbody System is an implantable device designed to be surgically placed within the cervical spine. It does not analyze or test samples like blood, urine, or tissue.
- The intended use is surgical fusion. The purpose of this device is to provide structural support and facilitate bone growth for spinal fusion, not to diagnose a condition based on in vitro analysis.
- The device description details an implant. The description focuses on the physical characteristics of the implantable device, such as its material, structure, and dimensions.
- The performance studies are mechanical tests. The studies described evaluate the physical strength and stability of the implant, which is relevant for a surgical device, not an IVD.
The information provided clearly describes a surgical implant for spinal fusion, which falls under the category of medical devices, but not specifically In Vitro Diagnostics.

Intended Use / Indications for Use
The ZSFab Cervical Interbody System is intended for anterior interbody fusion in skeletally mature patients who have had at least six weeks of non-operative treatment. The ZSFab Cervical Interbody System is indicated to treat cervical disc degeneration and/or cervical spinal instability, as confirmed by imaging studies (radiographs, CT, MRI), that results in radiculopathy, myelopathy, and/or pain at multiple contiguous levels from C2 - T1. The ZSFab Cervical Interbody System is designed for use with autogenous and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone to facilitate fusion and to be used with supplemental fixation cleared for use in the cervical spine.

Device Description
The ZSFab Cervical Interbody System includes additively manufactured interbody fusion devices for cervical implantation. The implants are designed with lattice structures to provide surgical stabilization of the spine. The lattices have near-elliptical pores with minor axis length of 720-760μm and major axis length of 1030-1060μm. Each interbody has a bone graft window that can be packed with bone graft material. The implants are available in a variety of height, length, width and lordotic angulation combinations to accommodate the patient specific anatomy and clinical circumstances.

Summary of Performance Studies
Mechanical testing of the worst case ZSFab Cervical Interbody System implant included static and dynamic axial compression and static and dynamic torsion according to ASTM F2077. In addition, subsidence according to ASTM F2267 and expulsion tests were performed. The mechanical test results demonstrate that the ZSFab Cervical Interbody System performance is substantially equivalent to the predicate devices.

§ 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 Karen Warden:
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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal
