Interbody Device (IBD) Implants (i.e., interbody implants used alone):
The SeaSpine Meridian System with NanoMetalene® surface technology when used with or without a Spin Plate, is indicated for use as an adjunct to fusion in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. These DDD patients may also have up to Grade 1 spondylolisthesis at the involved level(s). The interior of the device is to be used with autogenous bone graft and/or allogeneic bone graft composed of cancellous, cortical, and/or corticocancellous bone. The SeaSpine Meridian Interbody is intended for use with supplemental fixation. Degenerative disc disease is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and at least six (6) months of non-operative treatment.
No-Profile Implants w/ Screws:
The SeaSpine Meridian System No-Profile Interbody, when used with or without a No-Profile Locking Cover, is a standalone interbody implant indicated for use as an adjunct to fusion in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The DDD patients may also have up to Grade 1 spondylolisthesis at the involved level(s). The interior of the spacer component may be packed with autogenous bone graft and/or allogeneic bone graft composed of cancellous, cortical, and/or corticocancellous bone. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the device. Hyperlordotic sizes (greater than 20 degrees) are intended for use with supplemental fixation.
No-Profile Implants w/ Inline Fixation Anchors:
The SeaSpine Meridian System No-Profile Interbody, when used with Inline Fixation Anchors and a No Profile Locking Cover, is indicated for use as an adjunct to fusion in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The DDD patients may also have up to Grade 1 spondylolisthesis at the involved level(s). The interior of the spacer component may be packed with autogenous bone graft and/or allogeneic bone graft composed of cancellous, cortical, and/or corticocancellous bone. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the device. The SeaSpine Meridian No-Profile Implants w/ Inline Fixation Anchors is intended for use with supplemental fixation.
TruProfile Interbody Implants:
The SeaSpine Meridian System Interbody assembled with the Anterior Plate, when used with Screws, an Anterior Plate Locking Cover, and with or without a Spin Plate, is a standalone interbody implant indicated for use as an adjunct to fusion in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The DDD patients may also have up to Grade 1 spondylolisthesis at the involved level(s). The interior of the spacer component may be packed with autogenous bone graft and/or allogeneic bone graft composed of cancellous, cortical, and/or corticocancellous bone. Patients must have undergone a regimen of at least six (6) months of nonoperative treatment prior to being treated with the device. Hyperlordotic sizes (greater than 20 degrees) are intended for use with supplemental fixation.
Meridian Anterior Plate System
The Meridian Anterior Plate System is indicated as additional support during fusion via an anterior or anterolateral surgical approach above the bifurcation of the great vessels in the treatment of thoracic and thoracolumbar (T1-L5) spine instability or via the anterior surgical approach, below the bifurcation of the great vessels in the treatment of lumbar and lumbosacral (11-51) spine instability as a result of fracture (including dislocation and subluxation), tumor, degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), scoliosis, lordosis, spinal stenosis, or a failed previous spine surgery.
The SeaSpine Meridian System featuring NanoMetalene® surface technology are single-use intervertebral body fusion devices manufactured from polyetheretherketone (PEEK) (per ASTM F2026) with tantalum (per ASTM F560) and/or titanium alloy (Ti-6Al-4V ELI per ASTM F136) markers for radiographic visualization and NanoMetalene, which is a one-micron thick surface layer of commercially pure titanium (per ASTM F67). NanoMetalene surface technology provides a microscopic roughened surface with nano-scale features. The spacers are available in a variety of footprints, heights, and lordotic configurations to accommodate variations in pathology and patient anatomy and include a central graft window for receiving autogenous bone graft and/or allogenic bone graft, composed of cancellous, cortical, and/or corticocancellous bone prior to implantation. The spacers are individually packaged in a double PETG/Tyvek tray configuration and gamma sterilized. The Meridian System spacers can be used in combination with Spin Plates, Anterior Plates, Anterior Plate Locking Covers, Screws, Inline Fixation Anchors, and/or No-Profile Locking Covers; these implants are manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136) and are provided non-sterile.
The Meridian Anterior Plate System is comprised of single-use Anterior Plates, Screws, and Anterior Locking Covers, which are shared with the aforementioned Meridian SeaSpine System. The plates are offered in various heights and configurations, and they have no superior or inferior orientation requirement. The implants are manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136) and are provided non-sterile.
This document is a 510(k) Premarket Notification from the FDA for the SeaSpine Meridian System and Meridian Anterior Plate System. It describes the devices but does not contain information about acceptance criteria and a study to prove they meet the criteria in the way typically associated with AI/ML medical devices (e.g., performance metrics, ground truth, expert review).
The document states:
"Clinical Testing: Not applicable. The determination of substantial equivalence is not based on an assessment of clinical performance data."
Therefore, I cannot provide the requested information for acceptance criteria and a study proving device performance, as this type of data is explicitly stated as not applicable for this submission. The submission relies on demonstrating substantial equivalence to existing predicate devices through technological characteristics and non-clinical mechanical testing.
§ 888.3080 Intervertebral body fusion device.
(a)
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.(b)
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.
