The Kodiak Lumbar Spacer System is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels in the lumbar spine (L2-S1) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. Patients with previous non-fusion spinal surgery at the involved level may be treated with the Kodiak Lumbar Spacer System. Patients must have undergone a regimen of at least six (6) months of nonoperative treatment prior to being treated with the Kodiak Lumbar Spacer System.
The Kodiak Lumbar Spacer System is designed for use with autogenous bone graft. The system is also intended to be used with supplemental fixation systems that are cleared by the FDA for use in the lumbar spine.
The Met One Technologies Kodiak Lumbar Spacer System is a lumbar intervertebral body fusion device that is implanted into the vertebral body space to improve stability of the spine while supporting fusion. The Kodiak Lumbar Spacer System may be implanted bilaterally using a posterior (PLIF) approach, or as a single device employing a transformational (TLIF) approach. The implants have a central endplate window to permit packing of autograft and/or allograft bone, teeth on the superior and inferior surfaces, and lateral windows for radiographic visualization. The implants are additively manufactured from Ti-6A1-4V ELI and are available in a variety of heights, footprints, and lordotic configurations to suit individual patient anatomy.
The provided text describes the 510(k) premarket notification for the "Kodiak Lumbar Spacer System," an intervertebral body fusion device. This document is a regulatory submission for a medical device that does not involve Artificial Intelligence (AI).
The requested information pertains to studies proving device performance with AI, such as acceptance criteria for AI model performance, sample sizes for AI training and test sets, expert adjudication methods for AI ground truth, and AI-assisted reader studies. Since the Kodiak Lumbar Spacer System is a physical implant and not an AI-powered diagnostic or therapeutic tool, this document does not contain any of the information requested about AI device performance studies.
The "Performance Data" section lists several types of mechanical tests performed on the device in accordance with ASTM standards (e.g., Static Compression, Dynamic Compression, Subsidence, Expulsion). These tests are standard for orthopedic implants to demonstrate their structural integrity and function, but they are not related to AI performance.
Therefore, I cannot provide the requested information because the provided document does not discuss an AI device or its performance studies.
§ 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.
