Intended Use

The OptiMesh Multiplanar Expandable Interbody Fusion System is indicated for use as an adjunct to fusion in an intervertebral body fusion at one level in the lumbar spine from L2 to S1 in skeletally mature patients with degenerative disc disease (DDD) with up to Grade I spondylolisthesis at the involved level. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history, physical examination, and radiographic studies. Eligible patients shall have undergone six (6) months of conservative (non-operative) care. The OptiMesh device, along with a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion, is intended for use with supplemental posterior fixation systems intended for use in the lumbar spine.

Device Story

Non-rigid, expandable intervertebral body graft containment device; designed to contain FDA-cleared bone void filler within internal cavity. Implanted into intervertebral space during spinal fusion surgery; used as adjunct to fusion. Requires supplemental posterior fixation. Features optional nano-scale hydroxyapatite (HAnano Surface) treatment (20-40 nm thickness) to enhance surface properties. Operated by surgeons in clinical/OR settings. Provides structural containment for bone graft material to facilitate fusion; benefits patients by stabilizing intervertebral space in degenerative disc disease cases.

Clinical Evidence

No clinical data. Substantial equivalence supported by benchtop functional, mechanical, and adhesion testing, including ASTM standard testing, comparing the subject device to the predicate.

Technological Characteristics

Non-rigid, expandable mesh interbody graft containment device. Incorporates optional 20-40 nm hydroxyapatite (HAnano Surface) coating. Mechanical performance validated via ASTM testing. Standalone implant; requires supplemental posterior fixation. No software or electronic components.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) and up to Grade I spondylolisthesis at one lumbar level (L2-S1) who have failed 6 months of conservative care.

Regulatory Classification

Identification

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 available 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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

Purpose The purpose of this premarket notification is to obtain FDA clearance for a line extension of Implants to the OptiMesh Multiplanar Expandable Interbody Fusion System. The subject Implants incorporate a hydroxyapatite (HA$^{\text{nano}}$ Surface®) treatment to the Implant portfolio. The HA$^{\text{nano}}$ Surface® treatment presents a nano-scale topography on the entirety of the mesh component surface. # 2. Device Description The OptiMesh Multiplanar Expandable Interbody Fusion System is an intervertebral body graft containment device that is a non-rigid, implanted spinal device designed to contain FDA cleared bone void filler within its internal cavity. The device is inserted into the intervertebral body space of the spine and is intended as an adjunct to intervertebral body fusion. The OptiMesh implants are available with and without HA$^{\text{nano}}$ Surface®, a 20 – 40 nanometer thin hydroxyapatite (HA) surfaces treatment. {5} K2513020- Page 2 of 2 ## 3. Indications for Use The OptiMesh Multiplanar Expandable Interbody Fusion System is indicated for use as an adjunct to fusion in an intervertebral body fusion at one level in the lumbar spine from L2 to S1 in skeletally mature patients with degenerative disc disease (DDD) with up to Grade I spondylolisthesis at the involved level. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history, physical examination, and radiographic studies. Eligible patients shall have undergone six (6) months of conservative (non-operative) care. The OptiMesh device, along with a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion, is intended for use with supplemental posterior fixation systems intended for use in the lumbar spine. ## 4. Technological Characteristics The subject OptiMesh HA$^{\text{nano}}$ device is identical in technological characteristics to the predicate device but incorporates a nano-scale HA surface treatment which is identical in material to that provided on the reference device. The differences in technological characteristics do not raise difference questions of safety and effectiveness. ## 5. Non-Clinical Performance Testing The technological design features of the subject device are identical to the predicate device in intended use, indications for use, geometric design, design function, and technology, apart from the proposed addition of a hydroxyapatite surface treatment. Non-clinical testing was conducted to support the subject HA surface treated implants confirming function and performance and to demonstrate substantial equivalence. - Benchtop functional and mechanical characterization testing and comparison confirmed that the subject HA surface treated implants function as intended in comparison to the predicate device. - Benchtop performance adhesion testing confirmed mechanical function and material strength characteristics of the subject HA surface treated implants in comparison to the predicate device, with support from the reference device. - Benchtop performance ASTM testing and comparison confirmed that the subject HA surface treated implants perform as intended in comparison to the predicate device. ## 6. Clinical Performance Testing Clinical performance testing was not necessary to support the subject OptiMesh HA$^{\text{nano}}$ implants. ## 7. Conclusion The subject OptiMesh HA$^{\text{nano}}$ implants have been shown to be substantially equivalent to the legally marketed predicate device.
