Intended Use
The CONDUIT™ Cervical Cages with a microscopic roughened surface and micro and nano-scale features are intervertebral body fusion devices intended for use for anterior cervical in skeletally mature patients with cervical disc degeneration and/or cervical spinal instability, as confirmed by imaging studies (radiculopathy, myelopathy, myelopathy, and/or pain at multiple contiguous levels from C2 - Tl. The CONDUIT™ Cervical Cages are also to be used with supplemental fixation systems that have been cleared for use in the cervical spine. CONDUIT™ Cervical Cages are designed for use with autogenous and/or allogeneic bone graft comprised of cancellous, and/or cortiocancellous bone graft, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion.
Device Story
CONDUIT™ Cages are 3D-printed porous titanium interbody fusion devices; used to stabilize spinal segments and restore height in cervical (C2-T1) and lumbar (L2-S1) spine. Devices feature microscopic roughened surfaces with micro/nano-scale features. Used with autogenous/allogeneic bone graft or FDA-cleared bone void fillers (e.g., FIBERGRAFT™ BG Putty). Operated by surgeons in clinical settings; requires supplemental fixation (e.g., pedicle screws, plates). Input: patient anatomy/pathology; Output: structural support for fusion. Benefits: facilitates spinal fusion in degenerative disc disease patients. FIBERGRAFT™ BG Putty is an osteoconductive, resorbable bone void filler packed into defects; not for load-bearing; requires rigid stabilization.
Clinical Evidence
Retrospective study and two investigator-initiated studies (n=178 subjects) across multiple US sites. Evaluated radiographic and clinical outcomes, including fusion rates and adverse events, to support expanded indications for CONDUIT™ Cages used with FIBERGRAFT™ BG Putty. Data demonstrates performance and safety consistent with intended use.
Technological Characteristics
CONDUIT™ Cages: 3D-printed (Selective Laser Melting) Ti-6Al-4V ELI (ASTM F3001). Porous/solid geometry with micro/nano-scale surface features. FIBERGRAFT™ BG Putty: 45S5 bioactive glass with absorbable/polymeric carrier. Non-load bearing. Sterilization method not specified.
Indications for Use
Indicated for skeletally mature patients with cervical disc degeneration/instability (C2-T1) or lumbar degenerative disc disease (L2-S1) requiring interbody fusion. Includes patients with Grade I spondylolisthesis or retrolisthesis and those with prior non-fusion surgery. Requires 6 months of non-operative treatment. Used with supplemental fixation and bone graft/void fillers.

#### F. Device Description
The CONDUIT™ Technology platform is a comprehensive portfolio of 3D-printed porous titanium interbody devices intended to stabilize the spinal segment, restore intervertebral height and to facilitate interbody fusion in the cervical (C2-T1) and lumbar spine (L2-S1). Designed to treat cervical and lumbar degenerative disc disease, the platform consists of the Cervical, Transforaminal (TLIF), Lateral (LLIF), Anterior (ALIF) and Transforaminal/Posterior Lumbar (T/PLIF) systems. Each system features a full breadth of sizes, footprints, heights and angles. The devices are intended to be used with supplemental spinal fixation, either applied anterior or posterior (e.g. using posterior pedicle screws, anterior plate system or anterior screw and rod system).
The CONDUIT™ Cages are made from Ti-6A1-4V ELI conforming to ASTM F3001 with an additive manufacturing process (Selective Laser Melting). The design contains solid structures and porous structures. The hollow geometry of the implants allows them to be packed with autogenous, or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft, or a bone void filler as cleared by FDA for use in intervertebral body fusion.
The 3D Printed CONDUIT™ Cages have a microscopic roughened surface with micro and nanoscale features. The micro and nano features are on all surfaces of the cage, including the superior, inferior, and peripheral surfaces, as well as each member of the internal cell structure.
The FIBERGRAFT™ BG Putty is an osteoconductive, resorbable, biocompatible bone graft substitute to be gently packed into defect sites and to be used as non-structural scaffolds. The FIBERGRAFT™ BG putty is made from 45S5 bioactive glass, where the bioactive glass components are mixed with an absorbable/polymeric carrier to form a cohesive material.
{12}------------------------------------------------
The purpose of this submission is to expand the indications for the of CONDUIT™ Cages to include its use with FIBERGRAFT™ BG Putty. Additionally, the indications for the ALIF, TLIF, and T/PLIF cages are being expanded to include the use of allogeneic bone graft comprised of cancellous, and/or corticocancellous bonegraft.

# FIBERGRAFT™ BG Putty
FIBERGRAFT™ BG Putty - Bone Graft Substitute is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. FIBERGRAFT BG Putty is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space, extremities and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process. FIBERGRAFT BG Putty must be used with autograft in the posterolateral spine. When used in intervertebral body fusion procedures, FIBERGRAFT BG Putty must be used on its own with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
FIBERGRAFT BG Putty is not indicated for use in load-bearing applications; therefore, standard

### H. Summary of Similarities and Differences in Technological Characteristics, Performance, and Intended Use
The purpose of this Traditional 510(k) is to expand the indications for of the CONDUIT™ Cages to include its used with FIBERGRAFT™ BG Putty. Additionally, the indications for the ALIF, TLIF, and T/PLIF cages are being expanded to include the use of allogeneic bone graft comprised of cancellous, and/or corticocancellous bone graft. The subject device is substantially equivalent to the predicate devices with respect to indications, design, function, and performance. There are no differences in technological characteristics that will raise new concerns of safety or performance.
#### I. Materials
The CONDUIT™ Cervical and Lumbar Cages are all constructed from Standard Specification for Additive Manufacturing Titanium-6 Vanadium ELI with Extra Low Interstitials components using full-melt powder bed fusion in conformance with ASTM F3001. The BG Putty is composed of the same bioactive glass material with the same bioactive glass chemical composition and the same type and duration of patient contact as the predicate. The materials and manufacturing process for the CONDUIT™ subject devices are identical to that of the predicate device. Similarly, the materials and composition of the BG Putty device are identical to that of the predicate device and the manufacturing process remains substantially the same as that of the predicate. It is important to note that the manufacturing location of BG Putty was moved from Steris to Prosidyan (now DePuy Synthes), however the process has not changed.
#### J. Performance Data
The performance of the CONDUIT™ Cervical and Lumbar Cages and the FIBERGRAFTTM BG Putty have been assessed individually within their respective submissions (K201605, and K170306). Clinical data has been utilized to demonstrate the performance and safety of the expanded indications for use, which includes the use of the CONDUIT™ Cages with FIBERGRAFT™ BGPutty. The clinical data includes radiographic and clinical outcomes from a retrospective study and two investigator-initiated studies. The data provided includes 178 subjects and was collected from multiple sites across the United States (CA, TX, FL) to capture a variety of populations with diverse gender and racial/ethnic backgrounds that is representative of the intended users of the subject devices. The results of the data support the performance of the subject devices in intervertebral body fusion based on fusion and adverse event rates. Additional rationales were provided to justify the expanded indications based upon the clinical data results.
#### K. Conclusion
Based on the body of data presented throughout the submission, it has been determined that the subject devices are substantially equivalent to the predicate devices with respect to indications for use, technological characteristics, and performance data.
