Intended Use

The KIMBATM Spinal Implant is intended for use to replace a vertebral body that has been resected or excised due to tumor or trauma/fracture. The device is intended for use as a vertebral body replacement in the lumbar spine and is intended for use with supplemental internal fixation. The KIMBATM is intended to be implanted singularly. The supplemental internal fixation systems that may be used with the KIMBATM spinal implant include, but are not limited to, SIGNUS Coklusion rod system, DePuy AcroMed titanium plate or rod systems (Kaneda SR, University Plate, M-2, ISOLA, VSP, Moss, TiMX, and Profile).

Device Story

KIMBA is a hollow, curved frame spinal implant with tapered edges; features spikes and ridges on walls for anchorage and seating between vertebral bodies. Implanted by surgeons in the lumbar spine to replace resected or excised vertebral bodies due to tumor or trauma/fracture. Used singularly in conjunction with supplemental internal fixation systems (e.g., rod or plate systems). Provides structural support to the spinal column; benefits patient by restoring vertebral height and stability.

Clinical Evidence

Bench testing only. Testing included compression, torsion, and expulsion testing in compliance with FDA Guidance for Industry and FDA Staff Spinal System 510(k)s.

Technological Characteristics

Hollow, curved frame spinal implant; tapered edges; spikes and ridges for anchorage. Materials not specified (implied PEEK based on predicates). Mechanical fixation principle. Designed for lumbar vertebral body replacement.

Indications for Use

Indicated for patients requiring vertebral body replacement in the lumbar spine following resection or excision due to tumor or trauma/fracture. Must be used with supplemental internal fixation and implanted singularly.

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

Predicate Devices

• Curved PEEK TETRIS™ (K041888)
• RABEAT™ (K043316)
• PEEK Tetris™ (K031757)

| Device | The KIMBATM is a hollow, curved frame spinal implant with tapered |
| Description: | edges. The upper and lower aspects of the implant are open and the walls |
| | feature spikes and ridges which assist in the positive anchorage and seating |
| | of the implant between the superior and inferior vertebral bodies. |
| | |
| | The KIMBA®implant is available in a variety of sizes. This enables the |
| | surgeon to choose the size suited to the individual pathology and anatomy |
| | and condition and will be implanted individually. |
| Intended Use: | The KIMBATM Spinal Implant is intended for use to replace a vertebral |
| | body that has been resected or excised due to tumor or trauma/fracture. The |
| | device is intended for use as a vertebral body replacement in the lumbar |
