Indications for Use
The Sypher Spacer System is an intervertebral body fusion system indicated for intervertebral body fusion procedures in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use with autogenous bone graft at one or two contiguous levels of the lumbar spine (from L2 to S1) for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis at the involved level(s). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The device system is designed for use with supplemental fixation to facilitate fusion.
Device Story
Sypher Spacer System is an intervertebral body fusion device; consists of cylinder-shaped PEEK Optima LT1 blocks with tantalum radiological markers, titanium alloy self-drilling/self-tapping bone screws, and titanium cage lock assemblies. Designed for lumbar spine fusion (L2-S1); used with autogenous bone graft and supplemental fixation. Implants feature teeth on superior/inferior surfaces for stability; integrated anterior screw holes for medial screw placement; cage lock assembly secures screws. Used by surgeons in clinical settings to treat degenerative disc disease with spondylolisthesis or retrolisthesis. Provides structural support to facilitate spinal fusion; benefits patients by stabilizing the disc space to alleviate discogenic back pain.
Clinical Evidence
Bench testing only. Testing included static axial compression, static compressive shear, static subsidence, dynamic axial compression, dynamic compressive shear, and expulsion per ASTM F2077-11, ASTM F2267-04, and ASTM draft standards. Results demonstrate mechanical strength sufficient for intended use.
Technological Characteristics
Materials: PEEK Optima LT1 (ASTM F2026), tantalum alloy markers (ASTM F560), titanium alloy screws/lock assemblies (ASTM F136). Design: Cylinder-shaped blocks with teeth, integrated screw holes, and cage lock mechanism. Mechanical performance validated via ASTM F2077-11 and ASTM F2267-04. Standalone mechanical implant.
Indications for Use
Indicated for intervertebral body fusion in skeletally mature patients with degenerative disc disease (DDD) and up to Grade I spondylolisthesis or retrolisthesis at one or two contiguous lumbar levels (L2-S1) after six months of failed 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.
