Indications for Use
The PATHWAY Intervertebral body fusion device is intended for spinal fusion procedures at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by the history and radiographic studies. DDD patients may also have up to Grade I Spondylolisthesis or retrolisthesis at the involved levels. The patient may have had a previous non-fusion spinal surgery at the involved level(s). The device is intended to be used with supplemental spinal fixation systems that have been cleared for lumbosacral spine (i.e. posterior pedicle screws and rods systems and anterior screw and rod systems). The device is intended to be used with autogenous bone graft. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the PATHWAY AVID device. The PATHWAY AVID Intervertebral body fusion device must be inserted using a transforaminal approach.
Device Story
PATHWAY AVID is an articulated intervertebral body fusion device; constructed from multiple PEEK segments linked by titanium pins and linkage. Device footprint: 8-14mm height, 20mm width, 35mm length. Implanted via transforaminal approach by surgeons in clinical settings. Titanium pins serve as radiographic markers for intra/postoperative positioning. Used with supplemental spinal fixation (pedicle screws/rods) and autogenous bone graft to facilitate spinal fusion. Non-sterile; requires facility-based sterilization. Benefits include stabilization of spinal segments in DDD patients.
Clinical Evidence
No clinical trials performed. Substantial equivalence supported by bench testing per ASTM F2077 (static/dynamic compression, shear) and ASTM F2267 (subsidence), and cadaver testing to validate surgical approach and usability.
Technological Characteristics
Materials: PEEK (ASTM F2026) and Ti-6Al-4V titanium alloy (ASTM F136). Articulated, multi-segment design. Dimensions: 8-14mm height, 20mm width, 35mm length. Non-sterile; user-sterilized. Mechanical fixation via titanium pins/linkage. No software or energy source.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels (L2-S1), including those with Grade I Spondylolisthesis or retrolisthesis, or prior non-fusion spinal surgery. Requires 6 months of failed non-operative treatment. Contraindicated for patients without discogenic back pain or those not meeting skeletal maturity.
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.
