Active Implant Technology

Encapsulation Technology

Customized Encapsulation Technology for your Implant. CorTec is offering a wide spectrum of services accompanying you all the way through the development of innovative technologies leading to an approved medical device in the end. Our CorTec Encapsulation Technologies enable us to develop customized solutions for your specific requirements. We offer hermetically sealed encapsulations as well as non-hermetic solutions, like overmoulding technologies. Thanks to our development process and modern production technologies our team of highly skilled and experienced engineers can rapidly implement your design ideas and provide you with silicone moulding prototypes faster.

AirRay Electrodes

AirRay Grid and Strip Electrodes

Our Grid and Strip electrodes are designed to provide an electrical interface to the central nervous system. They are the ideal solution for ECoG or interoperative recordings. All contacts are able to record and stimulate. CorTec’s Grid and Strip electrodes are made from very soft silicone using a high-precision laser manufacturing process. They offer an unprecedented combination of flexibility, softness, stretchability, thinness and density of contacts.

AirRay Cuff Electrodes

Cuff electrodes are designed to provide an electrical interface to the peripheral nervous system. CorTec has developed several design families to meet the needs of the individual applications, which strongly depend on implantation site (e.g. nerve size) and character of the interface:Neural signal recording, Electrical stimulation of nerves, Blocking of propagation of neural signals. The cuffs are built from soft silicone to minimize the risk of mechanical nerve irritation. CorTec‘s micromachining technology permits the electrical contacts to be produced as micro meanders which are very flexible. At the same time they prevent the effect of plastic deformation of the cuffs during handling. The following page presents typical design options to these electrodes. Of course, we also offer custom-tailored designs to meet your specitic requirements.

Brain Interchange One

Multi-Part Implant

One or two of CorTecs °AirRay Electrodes. The Brain Interchange System can be equipped with adapters for DBS electrodes. The implanted internal electronics unit is placed inside a proprietary hermetic ceramic encapsulation. It amplifies, filters and digitizes neural signals and electrically stimulates neural tissue through the electrodes. It is inductively powered by the external unit and communicates with it via a broad-band radio link.

External Unit

A small, lightweight head piece is held attached to the skin by a magnet opposite to the implant. The communication unit for radio communication with the implant, typically belted to the upper arm or wheel chair of the patient, also controls the power supplied to the head piece and communicates with the controller computer. The External Unit consists of the Head Piece which supplies power inductively to the Implanted Internal Electronics Unit and to the Communication Unit. The Implanted Internal Electronics Unit communicates with the External Unit wirelessly through the skin via radio frequency transmission.
