When used as a cervical intervertebral body fusion device, the Zavation IBF implants are indicated for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients. Cervical IBF implants are intended for use at one level in the cervical spine, from C2 to T1, for the treatment of cervical disc disease (definded as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). The cervical device is intended to be used in patients who have had six weeks of non-operative treatment.
When used as a lumbar intervertebral body fusion device, the Zavation IBF implants are indicated for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients. The lumbar IBF implants are intended for use at either one level or two contiguous levels in the lumbar spine, from L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The lumbar device is intended to be used in patients who have had six months of non-operative treatment.
For all the above indications the Zavation IBF implants are intended to be used with supplemental internal fixation appropriate for the implanted level, including Zavation Spinal System and Zavation Cervical Plate System.
The Zavation IBF implants offers a variety of heights, widths and lengths. There are six main configurations: ALIF, LLIF, TLIF, T-PLIF, PLIF and CIF. The different configurations allow for multiple surgical technique options. The implants are manufactured from medical grade PEEK (Polyetheretherketone).
The Zavation IBF implants are available in a range of sizes, as well as parallel and lordotic angled implants, to accommodate variations in patients' anatomy. In addition, tantalum beads or pins are embedded in the implants as an option to help allow for radiographic visualization. The ends of the implants have machined teeth which are designed to engage with the vertebral body end plates.
The provided text is a 510(k) summary for the Zavation IBF System, which is an intervertebral body fusion device. This document details the regulatory classification, device description, intended use, and a comparison to predicate devices, but it does not describe acceptance criteria for a study proving device performance in the context of an AI/ML medical device, nor does it present a study of that nature.
The "Performance Data" section specifically states: "Mechanical test results demonstrated that the Zavation IBF System is substantially equivalent to the predicate devices. Testing was performed in accordance with: ASTM F2077, Test Methods for Intervertebral Body Fusion Devices - Static Axial Compression, Dynamic Axial Compression, Static Torsion (for cervical), Dynamic Torsion (for cervical). Testing per ISO 10993 was completed to demonstrate biocompatibility."
This indicates bench testing for mechanical properties and biocompatibility, which are standard for physical implantable medical devices. It does not involve AI/ML performance metrics, studies with human readers, or ground truth established by experts in the way requested for an AI/ML device.
Therefore, I cannot extract the requested information about acceptance criteria and a study proving an AI/ML device meets those criteria from this document. The document pertains to a physical medical device (intervertebral body fusion implant) and its regulatory clearance based on substantial equivalence to existing devices, primarily through mechanical and biocompatibility testing.
§ 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.
