JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
The Kimba Cage and the Translaminar Pin spinal implants were officially launched in May at the annual meeting of the German and French Society of Neurosurgeons in Strasbourg. Developed and manufactured by Icotec, the two implants are made with endless-fibre-reinforced composites – an advanced biocompatible material used for the first time for implants. The spinal implants specialist, Signus Medizintechnik in Germany, is distributor for these modern implants.

The Kimba Cage and the Translaminar Pin (TLP) are produced with icotec’s patented Composite Flow Moulding process and are made with endless carbon fibre (ECF) Peek-Optima® polymer. This biocompatible composite material, with an endless fibre content of over 60% by volume, distinguishes itself with its excellent mechanical strength and its fatigue resistance. Another feature of the material is its radiolucency, which allows artefact-free imaging in X-ray, magnetic resonance imaging (MRI) and computed tomography (CT). The polymer can be sterilised with all current methods used in hospitals today.
Excellent mechanical properties
High fatigue resistance is one of the key advantages of the TLP, which is used for the fusion of two or more motion segments of the lumbar spine.
Its trilobular thread is self-locking and its design is suitable for minimally invasive surgery.
The Kimba cage is used to treat mechanically caused pain due to degenerative lumbar intervertebral disc diseases or lumbar spondylolisthesis grade I-II.
The cage, made of ECF Peek-Optima®, is outstanding for its excellent mechanical properties and advantageous design features that optimise the surgical technique and ensure secure positioning of the implant.
The well-known spinal expert, Professor Friedrich Magerl, developed both implants through extensive research at icotec.
He used these first composite implants to implement his ideas and achieve the required product standards that are developing as orthopaedic and neurosurgeons discover the advantages of composites. Standard titanium implants that are subject to fatigue problems are being replaced in certain areas by biocompatible thermoplastic composites.
Icotec is continuously developing composite implants in cooperation with its partners.
The Kimba cage and the TLP are the first to receive the CE mark, and approval from the U.S. Federal Drug Administration (FDA) is expected for the second half of 2005. Further innovative products for the spine and also traumatology are to be expected soon.
