Intended Use

LnK Lumbar Interbody Fusion Cage System is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2-S1. 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).This device is to be used with autogenous bone graft. LnK Lumbar Interbody Fusion Cage System 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.

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.

#### Description of the Device 4.

The LnK Lumbar Interbody Fusion Cage System is intervertebral body fixation devices intended for use as an aid in spinal fixation. This system is fabricated and manufactured from PEEK-OPTIMA® LT1 as described by ASTM F2026. The Tantalum marker used for this product is made to the voluntary standard of ASTM F560. The devices are available in a variety of different sizes and heights to match more closely the patient's anatomy. The ends of the implants have machined teeth which are designed to engage with the vertebral body end plates. LnK Lumbar Interbody Fusion Cage System Implants

are supplied as sterile or non-sterile.

The LnK PLIF PEEK Cages are to be implanted via posterior approach. These devices are placed two implants on each side of the interbody space (right and left).

The LnK T-PLIF PEEK Cages which is used in transforaminal posterior lumbar interbody fusion technique. However, this kind of cage is to be implanted only one implant on interbody space.

The LnK TLIF PEEK Cages are a "banana" shaped. Implants are dedicated to transforaminal approach. TLIF technique involves placing only one bone graft spacer in the middle of the interbody space, without retraction of the spinal nerves.

The LnK ALIF PEEK Cages are to be implanted via anterior approach.

The LnK DLIF PEEK Cages are to be implanted via direct lateral interbody fusion approach. LnK DLIF PEEK Cage can be used in an open approach and a percutaneous approach with MIS instrumentation.

### Comparison of the technology characteristics of the device to predicate and 6. legally marketed devices

#### 7. Performance Data

Mechanical performance of additional components is same with predicated (K121096). Additional sizes are not worst case. Therefore, We substitute mechanical test data of additional components of LnK Lumbar Interbody Fusion Cage System with it of LnK Lumbar Interbody Fusion Cage System(K121096).

{6}------------------------------------------------

The LnK Lumbar Interbody Fusion Cage System was tested according to the ASTM F 2077, specifically, Static and Dynamic Axial Compression, Static and Dynamic Compression-Shear Testing, Static and Dynamic Torsion Testing, Expulsion Testing and Static Subsidence testing under Axial Compression, per ASTM F 2267.

#### Conclusion 8.

The additional components of LnK Lumbar Interbody Fusion Cage System are substantially equivalent to the device.
