Innovation at MIDES, further development of processes


As an innovative service and trading company, we see ourselves as a “one-stop shop” in the ultrasound segment of medical technology. In this way, we make a significant contribution to the security of medical care and sustainability of our customers. For us, quality is our top priority and that is why we continually invest in the further development of our technology and know-how. MIDES not only helps to optimize medical technology, but we also make it more sustainable with our 3 paths to the circular economy (REPAIR, REUSE, REFURBISH). 

The corporate philosophy of MIDES is based on the principle: “We make medicine greener.” According to this principle, with our 3 paths to the circular economy, we actively contribute to increasing sustainability in medical technology and avoiding electronic waste and waste of resources. With the MIDES Green Deal, uncomplicated, innovative and high-quality repairs and maintenance of refurbished by MIDES products go hand in hand with saving costs and resources. Repairing has many advantages and contributes to climate and environmental protection.


Thanks to our in-house innovation department with certified top technicians and close cooperation with experts from universities, we can guarantee the permanent expansion of our repair expertise as well as standardized and partially automated repair processes. Achieving the Quality Gates and MDR regulations is a top priority. We are constantly developing repair methods for ultrasound probes of all probe types and manufacturers and can offer new solutions, such as the mobile ultrasound probe “myMIDES” and the constantly growing range of refurbished by MIDES products.
