Intended Use

The CONDUIT™ ATP Inserters are intended to be used with the EIT Cellular Titanium® LLIF Cages. The EIT Cellular Titanium® LLIF Cages with a microscopic roughened surface and micro and nanoscale features are indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2-S 1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). These spinal implants are to be used with autogenous bone graft and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft. EIT Spine LLIF is to be used with supplemental fixation. Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral cage.

Device Story

CONDUIT™ ATP Inserters are reusable surgical instruments designed for Lumbar Interbody Fusion surgery via the ATP approach. Instruments interface with EIT Cellular Titanium® LLIF Cages to facilitate cage insertion. Used in operating rooms by surgeons; instruments provide mechanical handling and positioning of spinal implants. Device does not perform automated analysis or provide clinical decision support; it serves as a manual tool for implant delivery. Benefits include enabling precise placement of intervertebral fusion devices during spinal surgery.

Clinical Evidence

Bench testing only. Non-clinical performance testing included impaction endurance testing, formative usability testing, and thread cyclic testing. Results demonstrate performance is sufficient for intended use and equivalent to predicate devices.

Technological Characteristics

Manufactured from Stainless Steel (ASTM F899 or ASTM A693) and Silicone (ESP Class VI). Reusable, non-sterile instruments. Mechanical insertion tools for spinal implants. No software or electronic components.

Indications for Use

Indicated for use with EIT Cellular Titanium LLIF Cages in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2-S1. DDD defined as discogenic back pain with disc degeneration confirmed by history and radiography. Patients may have up to Grade 1 spondylolisthesis or retrolisthesis. Requires use with autogenous/allogeneic bone graft and supplemental fixation. Patients must have at least 6 months of prior non-operative treatment.

Regulatory Classification

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.

Special Controls

*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.

Dear Mr. Wright:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

### TECHNOLOGICAL CHARACTERISTICS

The CONDUIT™ ATP Inserters are manufactured from Stainless Steel per ASTM F899 or ASTM A693 and Silicone per ESP Class VI. The subject and predicate devices have nearly identical technological characteristics and the minor differences do not raise any new issues of safety and effectiveness. Specifically, the following characteristics are the same between the subject and predicates:

- Indications for use ●
- Materials of manufacture ●
- . Sterility
- . Compatibility

The differences in instrument handle design for surgeon utility and in handle materials and in the introduction of new instrument options (cobbs and spreaders) not previously part of the CONDUIT™ Inserter set do not

#### PERFORMANCE DATA

Non-clinical testing was conducted to confirm the device performance per intended use including impaction endurance testing, formative usability testing, and thread cyclic testing. The results of this non-clinical testing show that the performance of the CONDUIT™ ATP Inserters is sufficient for its intended use and is substantially equivalent to legally marketed predicate devices.

#### CONCLUSION

The overall technology characteristics and mechanical performance data lead to the conclusion that the CONDUIT™ ATP Inserters are substantially equivalent to the predicate device.
