Intended Use
The restor3d lumbar cages are intended to be used as an intervertebral body fusion device with bone graft for use in lumbar spine. They are indicated for use in skeletally mature patients with degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies) at one or two contiguous levels from L2-S1. DDD patients may also have up to grade 1 spondylolisthesis or retrolisthesis at the involved level(s). Implants are used to facilitate fusion in the lumbar spine using autograft and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the device is intended to be used with supplemental fixation systems that have been cleared for use in the lumbar spine.
Device Story
Additively manufactured titanium alloy lumbar interbody fusion implants; designed for PLIF, ALIF, OLIF, and LLIF surgical approaches. Implants feature central windows for bone graft packing and endplate surface lattices with teeth to resist migration. Used by surgeons in clinical settings to facilitate spinal fusion in conjunction with supplemental fixation systems. Benefits include stabilization of vertebral segments and promotion of fusion in patients with degenerative disc disease.
Clinical Evidence
Bench testing only. Mechanical performance evaluated via compression and compression-shear (ASTM F2077), subsidence (ASTM F2267), and expulsion testing.
Technological Characteristics
Material: Ti-6AL-4V titanium alloy (ASTM F2924). Additively manufactured. Features: central graft window, endplate surface lattices, and teeth for migration resistance. Various sizes/lordotic angles available. Sterile-packed.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (discogenic back pain, confirmed by history/radiography) at one or two contiguous levels from L2-S1, including those with up to grade 1 spondylolisthesis or retrolisthesis, who have failed at least 6 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.

Dear Shyam Patel:
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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

#### F. Device Description:
The restor3d TiDAL Lumbar Interbody Fusion System are additively manufactured Titanium Alloy (Ti-6AL-4V per ASTM F2924) implants, designed for use as a lumbar interbody fusion device. They are provided sterile-packed. The system is comprised of various sizes to accommodate individual patient anatomy as well as multiple designs to support several surgical techniques (PLIF, ALIF, OLIF, LLIF). Each approach includes several offerings that vary by footprint (width and depth/length), height, and lordotic angle. All sizes have a large central window(s) for packing autogenous bone graft and/or allogenic bone graft. The inferior and superior faces have endplate surface lattices as well as teeth to resist migration when placed in between the vertebral bodies.
#### G. Technological Characteristics:
As was established in this submission, the restor3d TiDAL Lumbar Interbody Fusion System is substantially equivalent to other predicate devices cleared by the FDA for commercial distribution in the United States. The subject device was shown to be substantially equivalent and have the same technological characteristics to its predicate devices through comparison in areas including design, intended use, implant materials, product features, mechanical performance, and function.
#### H. Performance Testing:
Mechanical Performance testing was performed through compression and compressionshear (ASTM F2077), subsidence testing (ASTM F2267), and expulsion testing. In all,

the restor3d TiDAL Lumbar Interbody Fusion System has demonstrated mechanical performance equivalence and is substantially equivalent to the predicate devices.
#### I. Conclusions:
The restor3d TiDAL Lumbar Interbody Fusion System was shown to be substantially equivalent in performance and have the same technological characteristics to its predicate devices through comparison in areas including design, intended use, implant materials, product features, mechanical performance, and function. Based on the data submitted, the restor3d TiDAL Lumbar Interbody Fusion System does not raise any new questions about safety or effectiveness, therefore, demonstrates substantial equivalence to the predicate devices.
