The Idys™ TLIF TiVac cages are indicated for use with autologous bone graft in patients with degenerative disc disease (DDD) at one or two levels from L2 to S1. These DDD patients may also have up to Grade 1 Spondylolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. These devices are intended for intervertebral body fusion, and are intended to be used with supplementation, which has been cleared by FDA for use in the lumbar spine.

Device Description

The Idys™ TLIF TiVac consists of interbody fusion devices intended for stabilization use and to promote bone fusion during the normal healing process following surgical correction of disorders of the lumbar spine.

The Idys™ TLIF TiVac cages, which have various widths and heights, are designed for use as lumbar intervertebral body fusion devices. The device has a shape which restores the intervertebral height and lordosis. The device contains two slots to receive the autologous bone graft to promote the fusion process between the endplates. The device has to be used with autograft.

The superior and inferior surfaces of the implant are designed with "teeth" to help prevent the device from migrating once it is positionally, the rough plasma-sprayed titanium surface interacts with the surface of the vertebral endblates and helps resist back out. The Idys™ TLIF TiVac cages are made of compliant ASTM F2026 polyetheretherketone (PEEK Optima®) with markers made of compliant ASTM F560 Tantalum and are coated with plasma-sprayed titanium compliant with ASTM F1580. Idys™ TLIF TiVac cages are positioned using a set of surgical instruments common for transforaminal lumbar approach. It is essential to insert implants with instrumentation specifically designed for this purpose. The cages are provided sterile and are for single use only.

AI/ML Overview

The provided text is a 510(k) summary for the Idys™ TLIF TiVac intervertebral body fusion device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than providing detailed clinical study results of new device performance against acceptance criteria. Therefore, much of the requested information regarding detailed acceptance criteria, sample sizes for test and training sets, expert qualifications, adjudication methods, MRMC studies, and stand-alone algorithm performance is not typically part of a 510(k) submission for this type of device and is not present in the provided text.

However, based on the information available, here's what can be extracted:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for substantial equivalence of the Idys™ TLIF TiVac are primarily based on demonstrating comparable performance to the predicate devices through mechanical testing and biocompatibility assessments. The "reported device performance" is essentially the statement that the device met these comparability goals.

Acceptance Criteria Category	Specific Test/Standard	Reported Device Performance
Biocompatibility	ISO 10993-1 Part 1	Modified device demonstrated to be biocompatible in accordance with ISO 10993-1 Part 1.

	ASTM F1147 (Static Tensile Strength)	Satisfactory results.
	ASTM F1160 (Shear Fatigue Strength)	Satisfactory results.
	ASTM F1978-99 (Abrasion Resistance)	Satisfactory results.
	ASTM F1854 (Coating Porosity/Thickness)	Satisfactory results.

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

Sample Size: Not specified in terms of number of devices or clinical cases. The tests described are bench mechanical and biocompatibility tests, not clinical performance tests on human subjects.
Data Provenance: The tests are described as "bench mechanical testing" and "biocompatibility testing," implying laboratory-based studies. The context suggests these were conducted by the manufacturer, Clariance SAS, a French company. Therefore, the data would be from non-clinical, prospective laboratory testing (meaning the tests were designed and conducted to evaluate the device as part of the submission process).

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

Not applicable. The "ground truth" for mechanical and biocompatibility testing is defined by the standards (ASTM and ISO) and the physical properties of the materials and device under test, not by expert consensus on clinical cases.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods are typically for clinical studies where human interpretation or classification is involved.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No. This type of study is for evaluating diagnostic or screening devices involving human readers interpreting medical images. The Idys™ TLIF TiVac is an intervertebral body fusion device (implant), not an imaging diagnostic tool.

6. Standalone Performance (i.e. algorithm only without human-in-the-loop performance)

Not applicable. This device is an implant, not an algorithm or AI system.

7. The Type of Ground Truth Used

The ground truth used for these tests is the quantitative and qualitative outcomes expected under the specified ASTM and ISO standards for mechanical stability, durability, and biocompatibility. For example, "satisfactory results" for coating tests imply meeting predefined thresholds or performance levels dictated by the standards.

8. The Sample Size for the Training Set

Not applicable. There is no mention of a "training set" as this is not a machine learning or AI device. The submission is based on engineering testing and comparison to predicate devices.

9. How the Ground Truth for the Training Set Was Established

Not applicable for the same reason as above.

Idys™ TLIF Cage, CLARIANCE SAS (K131178): primary predicate

Lucent® Ti-BOND® Spinal Elements (K150061): additional predicate (Titanium coating)

Purpose of the Traditional 510(k) notice

The Idys™ TLIF TiVac is a modification to the 510(k) approved Idys™ TLIF predicate (K131178). The modification consists of the addition of a plasma-sprayed, pure titanium coating compliant with ASTM F1580 on the superior and inferior surface of the The cages have equivalent design, shape, and dimensions as those already device. cleared under K131178 for the Idys™ TLIF cage predicate device.

Device Description

{4}------------------------------------------------

Intended Use/Indications for Use

The Idys™ TLIF TiVac cages are indicated for use with autologous bone graft in patients with degenerative disc disease (DDD) at one or two levels from L2 to S1. These DDD patients may also have up to Grade 1 Spondylolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. These devices are intended for intervertebral body fusion and are intended to be used with supplemental fixation instrumentation, which has been cleared by FDA for use in the lumbar spine.

Substantial Equivalence

The Idys™ TLIF TiVac cages and the predicate Idys™ TLIF (K131178) are designed for use as lumbar intervertebral body fusion devices. Both devices are available with equivalent range and configurations to accommodate patient anatomy.

The Idys™ TLIF TiVac and the Idys™ TLIF (K131178) cages feature a similar outer shape and design. Both devices are banana-shaped with a convex design and a bulleted nose. The shape is also similar to the Lucent® Ti-BOND® (K150061). The design features two slots to allow the incorporation of bone graft which is essential for promoting the fusion process. The superior and inferior surfaces of the Idys™ TLIF TiVac, the Idys™ TLIF (K131178) and Lucent® Ti-BOND® (K150061) have teeth to grip the surface of the vertebral endplates and help to resist expulsion.

The primary difference between the cleared Idys™ TLIF (K131178) and the subject device is the addition of the plasma-sprayed titanium coating on the superior and the inferior surface of the Idys™ TLIF TiVac cages. However, a similar coating has been cleared in the Lucent® Ti-BOND® (K150061).

Verification and validation steps performed following the titanium coating does not raise any new issues of safety or effectiveness compared to the cleared Idys™ TLIF cages (K131178).

Performance Data

Biocompatibility

The modified device has been demonstrated to be biocompatible in accordance with ISO 10993-1 Part 1.

Mechanical testing

Bench mechanical testing according to ASTM F2077 and ASTM F2267 were used to support the decision of substantial equivalence with Idys™ TLIF cages predicate device (K131178). Specifically, CLARIANCE performed static and dynamic axial compression testing, static and dynamic compression shear testing, subsidence testing, expulsion testing, static torsion testing, and wear testing (PEEK and titanium particles), all of which demonstrated the substantial equivalence of the system to legally marketed devices.

Mechanical bench testing of the pure titanium coating have been performed according to the FDA's guidance, Guidance for Industry on the Testing of Metallic Plasma Sprayed Coatings on Orthopedic Implants to Support Reconsideration of Postmarket Surveillance Requirements. Specifically, the following tests were performed: static tensile strength testing according to ASTM F1147, static shear strength according to ASTM F1044, shear fatigue strength according to ASTM F1160, abrasion resistance according to ASTM F1978-99, and coating porosity/thickness per ASTM F1854 with satisfactory results.

Conclusions

The Idys™ TLIF TiVac is equivalent to the Idys™ TLIF (K131178). The Idys™ TLIF TiVac has the same intended use and indications, technological characteristics, and principles of operation as its predicate device. The minor technological differences between the Idys™ TLIF TiVac and its predicate devices do not raise any new issues of safety or effectiveness compared to the predicate devices. Performance data demonstrate that the Idys™ TLIF TiVac is mechanically equivalent to its primary predicate.
