Indications for Use
The Prow Fusion is intended to be used for spinal fusion. The Prow-Fusion Intervertebral body fusion device is indicated for spinal fusion procedures at one or two contiguous levels from L2 through 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 spinal level(s). The device is intended to be used with supplemental spinal fixation systems that have been cleared for use in the lumbosacral spine (e.g. posterior pedicle 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 Prow Fusion device. The Prow Fusion intervertebral body fusion device must be inserted using a transforaminal approach.
Device Story
Prow Fusion is an intervertebral body fusion device for transforaminal lumbar interbody fusion (TLIF). Implant consists of multiple CFPEEK mid-segments and titanium end-segments, connected by titanium pins and UHMWPE suture. During implantation, suture pulls distal segment proximally to form a ring-shaped, closed-configuration implant within the disc space. Used with autogenous bone graft and supplemental posterior pedicle screw/rod fixation. Operated by surgeons in clinical/OR settings. Provides structural support to disc space to facilitate spinal fusion; benefits patients by stabilizing vertebral segments in DDD cases.
Clinical Evidence
Bench testing only. Performance evaluated per ASTM F2077 (static/dynamic axial compression, shear, torsion) and ASTM F2267 (subsidence, expulsion, wear). Cadaver testing confirmed device usability and surgical approach compatibility.
Technological Characteristics
Materials: CFPEEK (carbon fiber reinforced PEEK) and titanium alloy. Components: Multi-segment implant with serrated surfaces, titanium pins, and UHMWPE suture. Form factor: Expandable/configurable ring-shaped implant. Energy source: None (mechanical). Sterilization: Not specified. Connectivity: None.
Indications for Use
Indicated for spinal fusion at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD), including those with up to Grade I Spondylolisthesis or retrolisthesis. Includes patients with prior non-fusion spinal surgery. Requires 6 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.
