Indications for Use
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 nonfusion 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 PEEK-OPTIMA LT1/LT2 segments and titanium alloy end segments; segments are connected by a PEEK-OPTIMA LT2 strip. During surgery, the device is inserted into the disc space and the strip is used to pull the distal segment proximally, transforming the implant into a ring-shaped, closed configuration. Used with autogenous bone graft and supplemental posterior pedicle screw/rod fixation. Operated by surgeons in a clinical/OR setting. Provides structural support to the disc space to facilitate spinal fusion, potentially alleviating discogenic back pain.
Clinical Evidence
Bench testing only. Testing included static compression, static compressive shear, static torsion, dynamic compression shear, dynamic torsion, subsidence, expulsion, and particle analysis per ASTM F2077 and ASTM F2267 standards.
Technological Characteristics
Intervertebral body fusion device; materials: PEEK-OPTIMA LT1, PEEK-OPTIMA LT2, and titanium alloy. Features titanium pins and coarse surface finish on superior/inferior segments. Form factor: modular segments that form a ring-shaped configuration in situ. Transforaminal insertion approach. Reusable delivery system instruments. Mechanical testing per ASTM F2077 and ASTM F2267.
Indications for Use
Indicated for spinal fusion at 1-2 contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD), including those with up to Grade I Spondylolisthesis or retrolisthesis and prior non-fusion 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.
