The T-Space Spinal Implant System are indicated for spinal fusion procedures at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade 1 Spondylolisthesis at involved levels. These patients may have had previous non-fusion spinal surgery at the involved spinal level(s). The AIS T-Space Spinal Implant System is intended for use with supplemental spinal fixation systems that have been cleared for use in the lumbrosacral spine (i.e., posterior pedicle screw and rod systems, and anterior screw and rod systems). The AIS T-Space Spinal Implant System implants can be used individually or in pairs. The AIS T-Space Spinal Implant System is also intended for use with autogenous bone graft.

Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the Aesculap device.

Device Description

The T-Space Spinal Implant System is an intervertebral body fusion device that is implanted into the vertebral body space to improve stability of the spine while supporting fusion. The implants are offered in a coated and uncoated version and a variety of shapes and sizes to meet the requirements of the individual patient anatomy. The uncoated PEEK version is manufactured from PEEK - Optima (per ASTM F2026). The coated version will be the same in design as the uncoated PEEK implant with a titanium layer and a vacuum plasma spray coating (Plasmapore® - per ISO 5832-3). The device will have tantalum radiographic markers per ASTM F-560.

AI/ML Overview

I'm sorry, but based on the provided document, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets them, including details like sample sizes, data provenance, expert qualifications, and MRMC study information.

Here's why:

The document is a 510(k) Premarket Notification from the FDA. This type of document primarily focuses on establishing "substantial equivalence" to a legally marketed predicate device, rather than proving a device meets specific, novel acceptance criteria through a full clinical trial or detailed performance study.
The "Performance Data" section (page 5) describes non-clinical (mechanical) testing, not a clinical study. It lists various ASTM standards for static and dynamic mechanical properties, as well as coating-related tests. These tests are designed to show that the new device performs at least as well as, or exceeds the performance of, the predicate devices in these physical characteristics.
Missing Information: The document does not contain the following information you requested, as it is generally not part of a 510(k) summary for devices demonstrating substantial equivalence through non-clinical testing:
- Specific acceptance criteria beyond "meets or exceeds the performance of the predicate devices" in mechanical tests.
- Sample sizes for test sets in a clinical context.
- Data provenance (country of origin, retrospective/prospective for clinical data).
- Number and qualifications of experts for ground truth.
- Adjudication methods.
- MRMC comparative effectiveness study details.
- Standalone algorithm performance (as this is a physical implant, not an algorithm).
- Type of ground truth used (pathology, outcomes data, etc.).
- Training set sample size (for an AI/algorithm).
- How ground truth for a training set was established (for an AI/algorithm).

In summary, the provided text describes mechanical performance testing to demonstrate substantial equivalence of a spinal implant to predicate devices, not a clinical study with acceptance criteria related to patient outcomes or a study involving AI/algorithms or human readers.

INDICATIONS FOR USE

When used as an Intervertebral Body Fusion System:

The T-Space Spinal Implant System are indicated for spinal fusion procedures at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade 1 Spondylolisthesis or retrolisthesis at involved levels. These patients may have had previous non-fusion spinal surgery at the involved spinal level(s). The AIS T-Space Spinal Implant System is intended for use with supplemental spinal fixation systems that have been cleared for use in the lumbrosacral spine (i.e., posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems). The AIS T-Space Spinal Implants can be used individually or in pairs. The AIS T-Space Spinal Implant System is also intended for use with autogenous bone graft.

Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the Aesculap device.

DEVICE DESCRIPTION

{5}------------------------------------------------

TECHNOLOGICAL CHARACTERISTICS(compared to Predicate(s))

The components of the T-Space Spinal Implant System are offered in the same similar shapes and sizes as the predicate devices. The material used for the Aesculap® Implant Systems device is the same as that used to manufacture the predicate devices.

PERFORMANCE DATA

As recommended by the FDA Guidance for Spinal System 510(k)'s, non-clinical testing was performed to demonstrate that the AIS T-Space implants (coated and uncoated) are substantially equivalent to other predicate devices. The following testing was performed:

. Static torsion per ASTM F2077
Static and dynamic axial compression per ASTM F2077 ●
Shear resistance evaluation per ASTM F2267 .
. Subsidence per ASTM F2267

In addition to FDA's Spine Guidance. Aesculap has also completed non-clinical testing recommended in the "Guidance for Industry on the Testing of Metallic Plasma Sprayed Coatings on Orthopedic Implants to Support Reconsideration of Postmarket Surveillance Requirements." The following tests were performed:

Microstructure of the coating per ASTM F1854
Static Tensile Strength per ASTM F1147
Static Shear Strength per ASTM F1044
Shear Fatigue Test per ASTM F1160
Abrasion Resistance per ASTM F1978

The results of these tests showed that the T-Space Spinal Implant System meets or exceeds the performance of the predicate devices, and the device is therefore found to be substantially equivalent.

SUBSTANTIAL EQUIVALENCE

AIS believes that the T-Space Spinal Implant System is substantially equivalent to the design of the Spinal Elements Lucent System (K122967) and AIS PEEK VBR and Intervertebral Body Fusion Systems (K071983). The Plasmapore® coating has been used and cleared in a number of legally marketed product lines manufactured by Aesculap (hip, knee, and spinal implants) for many years. The most recent Spinal Implants to be cleared with the Plasmapore® coating is the CeSpace XP Intervertebral Body Fusion Device (K123909) and ProSpace XP Intervertebral Body Fusion Device (K132421).

PRIMARY PREDICATES:

Spinal Elements Lucent System (K122967) ●

ADDITIONAL PREDICATES:
