Intended Use

The PERIMETER® Interbody Fusion Device is indicated for interbody fusion with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous 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 implants may be implanted via a variety of open or minimally invasive approaches. These approaches include anterior, lateral and oblique. These devices are intended to be used with supplemental fixation instrumentation, which has been cleared for use in the lumbar spine.

Device Story

PERIMETER® Interbody Fusion Device consists of hollow cages (Titanium Alloy or PEEK) inserted between lumbar/lumbosacral vertebral bodies to provide support/correction during fusion surgery. Implants packed with autogenous bone graft; used with supplemental fixation instrumentation. Available in various sizes/lordosis angles; features surface teeth for expulsion resistance; Titanium version includes lateral windows for graft visibility. System includes reusable instruments (e.g., two-piece threaded inserter). Used by surgeons in open or minimally invasive (anterior, lateral, oblique) procedures. Device provides structural support to facilitate spinal fusion, potentially reducing discogenic back pain.

Clinical Evidence

Bench testing only. No clinical data provided. Validation focused on reprocessing and sterilization of the new inserter per ISO 17664, ISO 17665-1/2, AAMI TIR 12, AAMI TIR 30, and ANSI/AAMI ST79/ST81 standards.

Technological Characteristics

Materials: Titanium-6Aluminum-4Vanadium ELI or PEEK. Dimensions: 8-20mm height, 15-28mm length, 19-38mm width; 4-15 degree lordosis. Principle: Intervertebral body support/fusion. Connectivity: None. Sterilization: Sterile and non-sterile options provided. Software: None.

Indications for Use

Indicated for interbody fusion with autogenous bone graft in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, including those with up to Grade 1 Spondylolisthesis or retrolisthesis, who have failed six months of 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.

Predicate Devices

• PERIMETER® Interbody Fusion Device (K090353)
• PERIMETER® Interbody Fusion Device (K111525)

## V. Product Description

The PERIMETER® Interbody Fusion Device consists of cages of various widths and heights which can be inserted between two lumbar or lumbosacral vertebral bodies to give support and correction during lumbar interbody fusion surgeries. The hollow geometry of the implants allows them to be packed with autogenous bone graft. The PERIMETER® Interbody Device is to be used with supplemental fixation instrumentation.

The device is offered in both Titanium Alloy (Titanium-6Aluminum-4Vanadium ELI) and PEEK (Polyetheretherketone). This interbody device is offered in both sterile and non-sterile forms.

The PERIMETER® Interbody Fusion Device is offered in a variety of sizes ranging from 8mm to 20mm in height, 15 mm to 28mm in length and between 19mm and 38mm in width. An array of lordosis options are provided for this device spanning from 4 degrees to 15 degrees of angulation. Both the PEEK and Titanium Alloy devices are designed with teeth across both the superior and inferior surfaces to allow the implant to grip the superior and inferior end plates, thus providing expulsion resistance. Additionally; the Titanium Alloy version of this device offers lateral windows for visibility of the autogenous bone graft.

The purpose of this submission is to add a new inserter to the PERIMETER® Interbody Fusion Device system and to provide the package insert for this reusable device as well as other instruments for use with PERIMETER® Interbody Fusion Device. Additionally, the package insert for Medtronic's CATALYST® instruments, which can also be used with PERIMETER® Interbody Fusion Device, is provided. The modified design of the subject PERIMETER® Interbody Fusion Device does not affect the device's intended use or alter the device's fundamental scientific technology.

### VI. Indications for Use

The PERIMETER® Interbody Fusion Device is indicated for interbody fusion with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous 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 implants may be implanted via a variety of open or minimally invasive approaches. These approaches include anterior, lateral and oblique. These devices are intended to be used with supplemental fixation instrumentation, which has been cleared for use in the lumbar spine.

### VII. Summary of Technological Characteristics

The purpose of this Special 510(k) submission is to seek clearance to add a new twopiece threaded inserter to the PERIMETER® Interbody Fusion Device system. The design, materials, and fundamental scientific technology of the subiect PERIMETER® Interbody Fusion Device are identical to the predicate PERIMETER® Interbody Fusion Device, except for the addition of the subject inserter. The subject inserter is constructed of the same materials and represents the same fundamental scientific technology as the predicate inserter; however, the design consists of a two-piece construction in contrast to the 4-piece construction of the predicate inserter.

## VIII. Identification of the Legally Marketed Predicate Device Used to Claim Substantial Equivalence

Documentation was provided which demonstrated that the subject PERIMETER® Interbody Fusion Device system is substantially equivalent to the predicate PERIMETER® Interbody Fusion Device system cleared in K090353 (SE Sept 29, 2009) for the PEEK version, and K111525 (SE Aug 24, 2011) for the Titanium Alloy version. Additionally, CAPSTONE® Spinal System was used as a predicate for this submission since the design of the subject inserter is similar to the two-piece inserter recently cleared as part of CAPSTONE ® Spinal System (K103731, SE July 18, 2011).

## IX. Brief Discussion of the Non-Clinical Tests Submitted

The subject and predicate PERIMETER® Interbody Fusion Device devices are identical in terms of indications for use, intended use, performance specifications, and fundamental technological characteristics. Assessment of the instrument modifications has been completed in accordance with Medtronic design control processes. Cleaning and sterilization validations and assessments have been conducted according to the following standards to provide the appropriate disassembly, cleaning, and sterilization instructions for the new inserter, as well as the other instruments for use with PERIMETER® Interbody Fusion Device:
