Intended Use

The TiWAVE-C™ Porous Titanium Cervical Cage is intended for use in skeletally mature patients with cervical degenerative disc disease (DDD) at one level or two contiguous levels from C2 to T1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received six (6) weeks of prior non-operative treatment prior to treatment with the device. The devices must be used with supplemental fixation and must be used with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft when used as an adjunct to fusion.

Device Description

The TiWAVE-C™ Porous Titanium Cervical Cages are intervertebral body fusion devices made from additive manufactured (AM) Titanium Grade 23 per ASTM F3001. The implants are available in various heights and lengths to accommodate patients' anatomy. The implants are provided sterile.

AI/ML Overview

This is a medical device, specifically an intervertebral body fusion device, not an AI/ML powered device. Therefore, the questions related to AI/ML specific criteria (such as effect size of human readers with AI, standalone algorithm performance, sample size for training sets, and adjudication methods for experts) are not applicable.

However, based on the provided text, I can extract information regarding the device's non-clinical acceptance criteria and the study performed to prove it:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for the TiWAVE-C™ Porous Titanium Cervical Cage are based on demonstrating safety and performance equivalence to predicate devices through various mechanical and sterilization tests, adhering to industry standards.

Acceptance Criteria CategorySpecific Tests Performed (Industry Standards)Reported Device Performance/Conclusion
Mechanical SafetyStatic and dynamic axial compression (per ASTM F2077)Results of these evaluations indicate that the device is equivalent to the predicate device.
Static and dynamic torsion (per ASTM F2077)
Static compression shear (per ASTM F2077)
Subsidence (per ASTM F2267)
Static Expulsion
Sterilization EffectivenessEffectiveness of gamma irradiation validated using AAMI/ANSI/ISO 11137-2 – method VDmax25, including: Bioburden recovery factor testing, Bacteriostasis and fungistasis, Bioburden, Verification dose, Sterility testing of the verification dose sample.Results indicate satisfactory validation of the sterilization process. (Implicit, as the conclusion states no new safety/efficacy issues and equivalence to predicate)
Cleaning ProcedureEffectiveness of final ultrasonic cleaning procedure for gamma sterilization, including: Visual verification, Bioburden testing, Cytotoxicity testing, UV/Vis testing, Total organic carbon (TOC), Bacterial Endotoxin (LAL).Results indicate satisfactory validation of the cleaning procedure. (Implicit, as the conclusion states no new safety/efficacy issues and equivalence to predicate)
Packaging & ShippingEffectiveness of packaging and shipping of sterile product, including: Shipping testing, Peel strength testing, Bubble emission testing, Integrity inspections.Results indicate satisfactory validation of packaging and shipping. (Implicit, as the conclusion states no new safety/efficacy issues and equivalence to predicate)
Overall ConclusionSubstantial equivalence to predicate devices in terms of intended use, design, materials used, mechanical safety, and performances.Kalitec Direct, LLC considers the TiWAVE-C™ Porous Titanium Cervical Cage to be equivalent to the predicate devices. Based on the testing performed, it can be concluded that there are no new issues of safety or efficacy when comparing the subject device to the predicates.

2. Sample Size Used for the Test Set and the Data Provenance

The document does not specify the exact sample sizes (e.g., number of individual cages) used for each mechanical and sterilization test. However, it indicates that "the following tests were independently performed on the device," implying that multiple device samples were subjected to these tests to meet the relevant ASTM or ISO standards.

  • Data Provenance: The tests were "independently performed on the device," suggesting that the testing was conducted in a laboratory setting (likely by the manufacturer or a contracted third-party lab) to evaluate the physical characteristics and performance of the TiWAVE-C™ Porous Titanium Cervical Cages themselves, rather than collecting data from human subjects or existing patient records. Therefore, it is prospective data generation from device testing, not retrospective. Country of origin for data is not explicitly stated but implied to be related to the submitter (Kalitec Direct, LLC in Orlando, FL, USA).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

This question is not applicable to this type of device submission. There were no human experts establishing ground truth for a test set in the context of diagnostic accuracy or clinical interpretation. The "ground truth" for the device's performance is established by its compliance with recognized mechanical, material, and sterilization standards (ASTM, ISO).

4. Adjudication Method for the Test Set

This question is not applicable. No human adjudication was involved in evaluating the technical performance and safety of an intervertebral body fusion device based on mechanical and sterilization testing. The results are based on objective measurements against predefined standards.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This question is not applicable. The device is a physical intervertebral body fusion cage, not an AI-assisted diagnostic tool. No MRMC study was performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This question is not applicable. The device is a physical intervertebral body fusion cage, not an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for this device's acceptance is based on:

  • Engineering Standards: Compliance with established mechanical testing standards (e.g., ASTM F2077, ASTM F2267) for intervertebral body fusion devices. These standards define the expected performance characteristics (e.g., strength, durability).
  • Material Specifications: Conformance to material standards (e.g., ASTM F3001 for Titanium Grade 23).
  • Sterilization and Biocompatibility Standards: Compliance with standards for sterilization methods (e.g., AAMI/ANSI/ISO 11137-2) and cleanliness (e.g., cytotoxicity, bioburden, bacterial endotoxin).
  • Predicate Device Equivalence: The primary ground truth is also the demonstration of "substantial equivalence" to legally marketed predicate devices through comparative testing and analysis of design, materials, and intended use. The performance of the predicate devices, which are already deemed safe and effective, serves as the benchmark.

8. The sample size for the training set

This question is not applicable. There is no "training set" in the context of an AI/ML algorithm for this physical medical device.

9. How the ground truth for the training set was established

This question is not applicable. There is no "training set" for this physical medical device.
