Device Description
The Ventris system consists of intervertebral body fusion devices intended for lumbar interbody fusion using an anterior lumbar interbody fusion surgical approach (ALIF), anterolateral (i.e., oblique) lumbar interbody fusion surgical approach (AOLIF), or a lateral lumbar interbody fusion surgical approach (LLIF). The devices are intended to improve stability of the spine while supporting fusion. The Ventris constructs are intended for use at one or two contiguous levels in the lumbar spine (L2-S1). The components are offered in different shapes and sizes to meet the requirements of the individual patient's anatomy and are provided sterile.
Ventris cages are available in six configurations: Ventris Ti Interbody anterior four-hole constructs for ALIF approach, Ventris Ti FRA Interbody anterior fully round ALIF (FRA) constructs for ALIF approach, Ventris Ti Open Interbody anterior two-hole constructs for ALIF approach, Ventris Ti AL Interbody anterolateral (i.e., oblique) constructs for OLIF approach, Ventris Ti Lateral FX two-screw lateral constructs for LLIF approach, and Ventris Ti Lateral Interbody lateral constructs for LLIF approach. All cages are also available with increased surface area options that provide additional endplate surface area. For the increased surface area cages, the outer footprint remains the same, but the volume of the internal graft window is reduced, creating more endplate surface area.
Ventris cages are secured on the vertebral bodies using bone screws. A cover plate assembly prevents the screws from backing out after insertion. The cages and cover plates are made of titanium alloy (Ti-6Al-4V ELI) per ASTM F3001 Standard Specification for Additive Manufacturing Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) with Powder Bed Fusion. The bone screw and cover plate screws are made from titanium alloy (Ti-6Al-4V ELI) per ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications. All anterior and anterolateral constructs are zero profile, reducing potential for vessel interference with the anterior column.
All Ventris cages and cover plates are manufactured using the L-PBF (laser powder bed fusion) additive manufacturing method. L-PBF allows for the formation of solid, non-porous cages with a layered porous lattice structure on the surfaces of the components, including the surfaces of the interior graft window. This intricate structure facilitates bone in-growth by providing a larger surface of implant/bone contact than a buffed surface. Interbody cages and bone screws may also be titanium anodized to allow for identification of various heights/sizes by color.
Ventris Ti Interbody cages, Ventris Ti FRA Interbody cages, Ventris Ti Open Interbody cages, Ventris Ti AL Interbody cages, Ventris Ti Lateral FX Interbody cages, Ventris Ti Lateral Interbody cages, and Ventris bone screws are also available with a Proximal HA Surface (hydroxyapatite) coating. Cages and bone screws are coated with 20mm HA layer composed of crystalline hydroxyapatite particles that mimic human bone tissue through shape, composition, and structure. This surface treatment increases implant anchoring by facilitating osseointegration and enhancing early bone growth. All Ventris devices are only available sterile packaged.
Non-sterile, reusable surgical instruments to support implantation of the system are provided for use with Ventris devices are provided in steam sterilization trays.

Summary of Performance Studies
The subject device underwent mechanical performance testing to validate that the performance of the worst-case subject device is substantially equivalent to the previously cleared predicate devices. Worst-case testing also took into account the effect of all process steps, including HIP and Non-HIP test articles. Test methods include static compression, static compression shear, dynamic compression, and dynamic compression shear per ASTM F2077 Test Methods for Intervertebral Body Fusion Devices, and subsidence testing per ASTM F2267 Standard Test Method for Measuring Load Induced Subsidence of Intervertebral Body Fusion Devices Under Static Axial Compression. Mechanical testing ensured that the design features of the subject device met the required mechanical strength criteria for their intended use. Additional testing included tensile testing, microstructure assessment, and chemical composition assessment per ASTM F3001. The performance testing demonstrated substantial equivalence between the subject and predicate devices. The results of the non-clinical testing did not identify any new or increased risks associated with the change in additive manufacturing supplier. Performance equivalence demonstrated that the subject device met the acceptance criteria of the standards and is substantially equivalent to the predicate devices.

Page 8
The Ventris system consists of intervertebral body fusion devices intended for lumbar interbody fusion using an anterior lumbar interbody fusion surgical approach (ALIF), anterolateral (i.e., oblique) lumbar interbody fusion surgical approach (AOLIF), or a lateral lumbar interbody fusion surgical approach (LLIF). The devices are intended to improve stability of the spine while supporting fusion. The Ventris constructs are intended for use at one or two contiguous levels in the lumbar spine (L2-S1). The components are offered in different shapes and sizes to meet the requirements of the individual patient's anatomy and are provided sterile.
Ventris cages are available in six configurations: Ventris Ti Interbody anterior four-hole constructs for ALIF approach, Ventris Ti FRA Interbody anterior fully round ALIF (FRA) constructs for ALIF approach, Ventris Ti Open Interbody anterior two-hole constructs for ALIF approach, Ventris Ti AL Interbody anterolateral (i.e., oblique) constructs for OLIF approach, Ventris Ti Lateral FX two-screw lateral constructs for LLIF approach, and Ventris Ti Lateral Interbody lateral constructs for LLIF approach. All cages are also available with increased surface area options that provide additional endplate surface area. For the increased surface area cages, the outer footprint remains the same, but the volume of the internal graft window is reduced, creating more endplate surface area.
Ventris cages are secured on the vertebral bodies using bone screws. A cover plate assembly prevents the screws from backing out after insertion. The cages and cover plates are made of titanium alloy (Ti-6Al-4V ELI) per ASTM F3001 Standard Specification for Additive Manufacturing Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) with Powder Bed Fusion. The bone screw and cover plate screws are made from titanium alloy (Ti-6Al-4V ELI) per ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications. All anterior and anterolateral constructs are zero profile, reducing potential for vessel interference with the anterior column.
All Ventris cages and cover plates are manufactured using the L-PBF (laser powder bed fusion) additive manufacturing method. L-PBF allows for the formation of solid, non-porous cages with a layered porous lattice structure on the surfaces of the components, including the surfaces of the interior graft window. This intricate structure facilitates bone in-growth by providing a larger surface of implant/bone contact than a buffed surface. Interbody cages and bone screws may also be titanium anodized to allow for identification of various heights/sizes by color.
Ventris Ti Interbody cages, Ventris Ti FRA Interbody cages, Ventris Ti Open Interbody cages, Ventris Ti AL Interbody cages, Ventris Ti Lateral FX Interbody cages, Ventris Ti Lateral Interbody cages, and Ventris bone screws are also available with a Proximal HA Surface (hydroxyapatite) coating. Cages and bone screws are coated with 20mm HA layer composed of crystalline hydroxyapatite particles that mimic human bone tissue through shape, composition, and structure. This surface treatment increases implant anchoring by facilitating osseointegration and enhancing early bone growth. All Ventris devices are only available sterile packaged.
Non-sterile, reusable surgical instruments to support implantation of the system are provided for use with Ventris devices are provided in steam sterilization trays.

Differences in technological characteristics from the predicate devices include introduce a change in the device name, additional implant height and lordosis offerings, additional implant configurations with increased surface area options, additional bone screw and cover plate options, an update to instrument designs, and additional instrument options. Furthermore, the additive manufacturing process was changed to a new supplier.
The subject device has identical or similar technological characteristics as the reference predicate devices cleared in K222561, K230894, K232282, and K223413 with an extended range of implant sizes and lordosis. The subject device also has similar indications for use as the devices cleared in K230894, K232282, and K223413. The subject device comes with an optional HA coating, which is the same material as the device cleared in K222561.
In order to ensure that these technological characteristics do not affect the safety and effectiveness of the subject device, mechanical testing and a worst-case analysis was conducted on the new implant sizes and configurations. Based on the testing conducted, including mechanical performance testing, design validation analysis, biocompatibility testing, and sterilization and packaging validation, it can be concluded that the subject device does not raise new issues of safety or effectiveness compared to the predicate devices K201671, K222561, K230894, K232282, and K223413.
The Ventris system is substantially equivalent to and is as safe and effective as the legally marketed predicate device, A-Link Z (K201671) under regulation 21 CFR 888.3080, product codes OVD and MAX.
Non-Clinical and/or Clinical Tests Summary & Conclusions
21 CFR 807.92(b)
The subject device underwent mechanical performance testing to validate that the performance of the worst-case subject device is substantially equivalent to the previously cleared predicate devices. Worst-case testing also took into account the effect of all process steps, including HIP and Non-HIP test articles. Test methods include static compression, static compression shear, dynamic compression, and dynamic compression shear per ASTM F2077 Test Methods for Intervertebral Body Fusion Devices, and subsidence testing per ASTM F2267 Standard Test Method for Measuring Load Induced Subsidence of Intervertebral Body Fusion Devices Under Static Axial Compression. Mechanical testing ensured that the design features of the subject device met the required mechanical strength criteria for their intended use. Additional testing included tensile testing, microstructure assessment, and chemical composition assessment per ASTM F3001. The performance testing demonstrated substantial equivalence between the subject and predicate devices. The results of the non-clinical testing did not identify any new or increased risks associated with the change in additive manufacturing supplier. Performance equivalence demonstrated that the subject device met the acceptance criteria of the standards and is substantially equivalent to the predicate devices.
Ventris devices are substantially equivalent to the previously cleared devices with respect to their indications for use, design, function, and performance.
