Electronics Development for Implantable Devices

Reliable and transparent development processes for electronics can be challenging  – with our team we guide you through the electronics development.

Our Electronics Development

Our electronics engineers have many years of experience in CAE-design for medical circuits according to ISO-13485. If you already know the needed specifications we are happy to join you on your journey and to develop electronics with you.   

PCB Design

We help you to transform your concept and ideas into fabricated circuit boards.

  • We understand the special needs of med-tech – Our development process includes checklist generated for med-tech PCBs.
  • Creation of schematics for active implants and external components.
  • Board Layout (Analog design, digital design, RF-circuits, smallest-size, ridged-flex,…)
  • Prototype manufacturing and qualification
  • Enabling series-production with certified EMS-suppliers using detailed generated manufacturing data
  • Smart system tests for series production.

Wireless Communication Module

  • Reliable data transmission concepts for your medical device
  • Various data links available: 2.4 GHz proprietary, bluetooth, optical and near field.
  • Module can be used for fast, low-power, bidirectional transcutaneous data transmission.

Inductive Power Link

  • We offer solutions for transcutaneous powering or wireless charging.
  • Various implantation depths of the implant can be realized.
  • Adaptation of Brain Interchange transcutaneous inductive power transfer mechanism.
  • Power Link Module rectifies and regulates the voltages and performs watchdog checks.
  • Power Link Module can be adjusted in size and performance to fit your specific needs.
  • Simulation-models are generated for design optimization

Recording Module

  • Use CorTec’s own ASIC-micro-chip for precise and fast analog signal processing and digitizing of ECoG, iEEG, DBS and peripheral signals.
  • Small electronic modules using the CorTec-ASIC can be tailored to your specific requirements.

Stimulation Module

  • Development of neural stimulator circuits, capable of fast switching to deliver precise and timely stimulation.
  • ASIC-micro-chip forswitching and stimulating on of ECoG, iEEG, DBS and peripheral electrodes.
  • Small electronic modules using the CorTec-ASIC can be tailored to your specific requirements.

Closed-Loop Module

  • Development of active implant Closed-Loop modules based on the Brain Interchange platform technology
  • Custom made ASIC is used for stimulation as well as recording.
  • Fast response times, even with wireless data transmission.
  • Optimization for small delays: data transmission chain, ASIC-recording, microcontroller, rf-transmitter, rf-receiver, USB-transmission, PC-driver, ASIC-stimulation.
  • Small electronic modules using the CorTec-ASIC can be tailored to your specific requirements.

Wearable Device

  • External components of the CorTec Brain Interchange can be customized to customer needs
  • Bidirectional data-link to the implant
  • Inductive powering
  • Linux-based micro-computer-board
  • Integration of rechargeable batteries is possible

Test Bench Development

For qualification as well as for the series production process of our products, CorTec designed several test-stations, which are specialized for automatic implant-qualification.

Prototype Manufacturing

Building up electronic circuits, 3D-prints as well as complete implants is our daily business. We have electrical laboratories with the latest soldering stations and measurement equipment.
