Indications for Use
The AccuLIF TL and PL Cages are indicated for intervertebral body fusion with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft when the subject device is used as an adjunct to fusion in patients with degenerative disc disease (DDD) at one level 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. These DDD patients may also have up to Grade I spondylolisthesis at the involved level(s). These patients should be skeletally mature and have completed six months of non-operative treatment. Additionally, the AccuLIF TL and PL Cages can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis. The AccuLIF TL and PL Cages are always to be used with supplemental internal spinal fixation. Additionally, the AccuLIF TL and PL Cages are to be used with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft when the subject device is used as an adjunct to fusion.
Device Story
Expandable interbody fusion cage; used in lumbar spine (L2-S1). Device inserted in unexpanded state via delivery handle; expanded in-situ to required height using hydraulic system (disposable flexible tubing set and inflation syringe). Hydraulic pressure drives 2 cylinder/piston arrangements; device locks automatically at 1mm increments. Used by surgeons in OR. Provides structural support for fusion; benefits patient by restoring disc height and facilitating spinal stabilization. Modifications in this submission concern tubing sets only; no changes to implant.
Clinical Evidence
Bench testing only. Design verification testing conducted to assess tubing set modifications; results demonstrate substantial equivalence to the predicate.
Technological Characteristics
Expandable interbody fusion cage. Materials: Titanium alloy (Ti6Al4V ELI, ASTM F138-08), Stainless Steel (316 LVM, ASTM F138-08), Silicone Rubber (MED-4870). Hydraulic expansion mechanism; manual inflation syringe; disposable tubing. Mechanical locking at 1mm increments. Various sizes, shapes, and lordotic angles.
Indications for Use
Indicated for intervertebral body fusion in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels (L2-S1) or degenerative scoliosis. DDD patients may have up to Grade I spondylolisthesis. Requires six months of failed non-operative treatment. Must be used with supplemental internal spinal fixation and autograft/allogenic bone graft.
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.
