Medical-technological devices shall usually just fulfill the intended function. But we are aware that they need to be able to do more because they are used and operated by humans. More than a safe, registered product is necessary to be successful in the health market. For the third generation of therapy devices (SPIN·SYSTEMS) the EVOCONTOUR product design was developed that attracts attention and lends an emotional quality and charisma to the medical-technological functionality. Design for us does not only encompass the form and aesthetics but we have expanded it to include intuitive operability and highest possbile product safety.
