The Kyocera Medical Technologies, Inc. (KMT) Tesera-k Anterior Lumbar Interbody Fusion (ALIF) System is indicated for interbody fusion procedures in skeletally mature patients with disc disease (DDD) in the lumbar spine at one or two contiguous levels from L2 to S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These DDD patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). KMTI Tesera-k ALIF System implants are to be used with autogenous bone graft. Patients should be skeletally mature and have at least six months of nonoperative treatment. The Tesera-k ALIF System implants are available in standalone (Tesera-k SA) and non-standalone (Tesera-k A) configurations.
Tesera-k SA ALIF cages are intended to be implanted from a direct anterior surgical approach only. Tesera-k SA ALIF cages are intended to be used with the coverplate and screws provided. Tesera-k SA ALIF assemblies (cage, screws, coverplate) that contain cages with lordotic angles less than 20° and use all four screws are standalone and require no supplemental fixation. Tesera-k SA ALIF assemblies (cage, screws, coverplate) that contain cages with lordotic angles greater than or equal to 20° or if the surgeon chose to use fewer than four screws are considered non-standalone and require supplemental fixation cleared by the FDA for use in the lumbosacral spine.
Tesera-k A ALIF cages are monolithic and do not interface or mate with any additional implants. Tesera-k A ALIF cages may be implanted from direct anterior or oblique insertion angle. Tesera-k A ALIF cages are non-standalone and require supplemental fixation cleared by the FDA for use in the lumbosacral spine.
The Kyocera Medical Technologies, Inc. (KMT) Tesera-k Anterior Lumbar Interbody Fusion (ALIF) System implants support foraminal height and decompression between lumbar or lumbosacral vertebral bodies during spinal correction and fusion as well as reusable instruments to assist in endplate preparation and implantation. The Tesera-k ALIF System implants are available as a monolith without integrated fixation (Tesera-k A) or as a standalone with integrated fixation (Tesera-k SA) and are additively manufactured from Ti-6Al-4Vper ASTM F2924. The Tesera-k SA constructs includes screws and a coverplate manufactured from Ti-6Al-4V per ASTM F136 from the Tesera SA ALIF System (K193320, K131122, K140106, and K180502). The Tesera-k ALIF implants are sterile packaged and inserted via a direct anterior or oblique anterior surgical approach. The Tesera-k ALIF implants are offered in a variety of sizes and lordosis options to meet patient anatomical needs.
I am sorry, but the provided text does not contain information about acceptance criteria and the study that proves the device meets the acceptance criteria for a medical device that uses AI. The document is an FDA 510(k) clearance letter and summary for a spinal interbody fusion device (Tesera-k ALIF System), which is a physical implant, not an AI or software-based device.
Therefore, I cannot provide details on:
- A table of acceptance criteria and reported device performance (for AI).
- Sample size and data provenance for a test set (for AI).
- Number and qualifications of experts for ground truth (for AI).
- Adjudication method (for AI).
- Multi-reader multi-case (MRMC) comparative effectiveness study with AI.
- Standalone AI performance.
- Type of ground truth used (for AI).
- Sample size for the training set (for AI).
- How ground truth for the training set was established (for AI).
The document focuses on the mechanical performance data (static and dynamic axial compression, compression shear, and subsidence) for the physical implant as per ASTM standards, concluding that the Tesera-k ALIF System is substantially equivalent to predicate devices based on these non-clinical tests.
§ 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.
