Proprietary Trade Name: FlareHawk Interbody Fusion System IV. Common Name: Intervertebral Body Fusion Device with Bone Graft, Lumbar V. Classification Name: Intervertebral Body Fusion Device (21 CFR 888.3080) Class: II Product Code: MAX VI. Product Description FlareHawk Interbody Fusion System is an expandable lumbar intervertebral body fusion device intended for use in the lumbosacral spine from L2 to S1. The FlareHawk interbody fusion device consists of a shell and a shim component that are offered in various lengths, heights, and lordotic angles to accommodate variations in patient anatomy. When the FlareHawk device is deployed within the intervertebral disc space, the shell and shim components lock together to create a complete implant construct to provide structural stability for interbody fusion. The final dimensions of the deployed device construct are determined by the dimensions of the selected shell and shim. Once implanted, the FlareHawk interbody fusion device is designed to restore intervertebral disc height, {5} provide anterior column support, and maintain structural stability of the motion segment to facilitate intervertebral body fusion. The FlareHawk Interbody Fusion device is intended to be used with autogenous bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone, and with supplemental fixation instrumentation that has been cleared for use in the lumbar spine. The FlareHawk Interbody Fusion System includes manual surgical instruments for delivery of the implant device and for disc preparation. ## VII. Indications for Use The FlareHawk Interbody Fusion System is indicated for spinal intervertebral body fusion with autogenous bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone in skeletally mature individuals with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, following discectomy. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have at least six (6) months of non-operative treatment. Additionally, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). FlareHawk system spacers are intended to be used with supplemental fixation instrumentation, which has been cleared for use in the lumbar spine. ## VIII. Summary of Technological Characteristics The subject FlareHawk Interbody Fusion System has the identical fundamental scientific technology as the predicate FlareHawk Interbody Fusion System. Like the predicate FlareHawk Interbody Fusion System, the shell component of the subject FlareHawk Interbody Fusion System implants is a rectangular frame that is inserted into the disc space in a non-expanded form, with subsequent in-situ expansion resulting from the insertion of the shim component. The shim locks to both the shell core and the posterior of the shell when the implant is deployed. K243116 Page 2 of 4 {6} Like the predicate FlareHawk Interbody Fusion System, the subject shell component is manufactured from PEEK per ASTM F2026, and incorporates an integrated core manufactured from titanium alloy per ASTM F136, and tantalum markers per ASTM F560 for imaging purposes. The subject shell components are offered in both non-coated and coated with CP titanium (Grade 2 commercially pure titanium that meets the chemical composition requirements of ASTM F67) versions. The shell component features a bulleted nose designed to facilitate ease of insertion, as well as directional teeth on its superior and inferior surfaces to resist expulsion. Like the predicate FlareHawk Interbody Fusion System, the shim component of the subject FlareHawk Interbody Fusion System implants has a tapered front end that inserts into and expands the shell component to the desired height and lordosis. The shim is manufactured from titanium alloy per ASTM F136 and are color anodized for differentiation. Like the predicate FlareHawk Interbody Fusion System, the subject shells and shims are offered in both non-sterile (and intended to be steam sterilized by the user) and gamma sterilized versions. IX. Identification of Legally Marketed Predicate Devices Used to Claim Substantial Equivalence To demonstrate the substantial equivalence of the subject FlareHawk Interbody Fusion System to legally marketed predicate devices, FlareHawk Interbody Fusion System K202198 (SE 11/03/2020) is used as the primary predicate device. Integrity Implants' FlareHawk Interbody Fusion System K220453 (SE 03/24/2022) is also used as a predicate for this submission. X. Brief Discussion of the Non-Clinical and Clinical Tests Submitted Bench performance testing conducted in support of this premarket notification submission included an evaluation of magnetic field interactions, artifacts, and radio frequency induced heating in accordance with the following standards: - ASTM F2052 Standard test method for measurement of magnetically induced displacement force on passive implants in the magnetic resonance environment K243116 Page 3 of 4 {7} - ASTM F2213 Standard test method for measurement of magnetically induced torque on medical devices in the magnetic resonance environment - ASTM F2119 Standard test method for evaluation of MR image artifacts from passive implants - ASTM F2182 Standard test method for measurement of radio frequency induced heating on or near passive implant during magnetic resonance imaging In addition to bench performance testing, validated modeling studies were conducted to confirm the worst case device configuration for MR induced heating, as well as to assess worst case in-vivo heating in clinically-relevant muscle-like and bone tissues. ## XI. Conclusions Drawn for the Non-Clinical and Clinical Tests Based on the MRI safety testing, modeling studies, and other supporting documentation provided in this premarket notification, the subject FlareHawk Interbody Fusion System demonstrates substantial equivalence to legally marketed predicate devices, including the previously cleared FlareHawk Interbody Fusion System.
