Sternal Fixation System

A totally non-metallic solution dedicated for reliable and rigid fixation of the sternum

PEEK-OPTIMA® polymer, provided by lnvibio, is now recognized as a high perfor­mance biomaterial in worldwide. It is formulated to meet the most exacting in-vivo criteria and present excellent mechanical performance, plasticity, chemical resistance and biocompatibility. It is also capable to be repeatedly sterilized without impairing performance and behaves highly radiolucent CT/MRI imaging without scattering or artifacts. PEEK-OPTIMA polymer has been widely utilized in cardiovascular, dental, neurological and orthopaedic implants and globally accumulated more than 9 million implant cases.

Excellent Imaging Compatibility

PEEK is a high molecule polymer with better imaging compatibility.

  • Non-magnetic and MRI safe
  • Highly translucent to X-ray and CT compatible
  • Artifact-free and scattering-free

CT value of PEEK sternal band: 50-l00H u

Biological Compatibility

PEEK performs excellent histocompatiblity and biological characteristics. Capable to sustain repeated steam, ETD sterilization and Gamma irradiation. Non-cytotoxic, non-carcinogenic, non-conductive,hydrolysis resistance and corrosion resistance.


  • Withstand 3,000 times of autoclave sterilization at 134°
  • Corrosion resistance and fatigue resistance
  • No deformity after gamma radiation

Tried and Tested

Test material implanted in paravertebral muscle for one year caused virtually no response-mild fibrosis, or in some cases a light fibrous capsule. There was no muscle degeneration, nor necrosis, or any other significant change.

PEEK-OPTIMA® Biocompatibility Tests

  • Genotoxicity ISO 10993-3
  • Hemolysis (Extract) ISO 10993-4
  • Cytotoxicity ISO 10993-5
  • Biostability Local Effects of Implantation ISO 10993-6
  • Sensitization ISO 10993-10
  • Pyrogenicity ISO 10993-11
  • Chemical Analysis ISO 10993-18
  • USP Plastic Class VI Systemic Toxicity Study
  • USP Plastic Class VI lntracutaneous Toxicity Study

PEEK-OPTIMA® is an inherently pure inert material. Extensive biocompatibility testing demonstrated no evidence of cytotoxicity, systemic toxicity, irritation or any macroscopic reaction response.

Outstanding Bio-Mechnical Character

Exceeding tensile strength to native bone with better protection.
Comparable mechanical strength to native bone and capable to distract stresses effectively when deformity occurs.
