Learn more about the unique benefits
of working with MDT:



Medical Device Testing Services (MDT) was founded in 1990 as a division of EnduraTEC Systems Corporation, which specialized in the development of novel material test instruments for the medical device community. In 2000, MDT was spun off as a separate company to provide greater focus on testing services. Throughout its 25 year history, the company has tested many new designs including stents, grafts, pacemaker leads, heart valves, vena cava filters, defibrillators, percutaneous heart valves, and many other devices. Under the leadership of Kent Vilendrer, Founder and CEO, MDT has been a world leader in the development of proprietary test instruments, controls, fixtures, standards and test protocols. Kent holds 6 patents in materials testing, bioreactor designs, fatigue test systems and test fixtures including the original patent 5,670,708 for the 9100 Series Stent Graft Testers as well as several patents pending. In 2004, the equipment manufacturing part of EnduraTEC was sold to Bose Corporation and the group was subsequently renamed the Bose ElectroForce Group (now part of TA Instruments). EnduraTEC’s contract testing business was retained and renamed to Medical Device Testing Services.

The company's state of the art 10,300 square foot facility in Minnetonka, MN (western suburb of the Twin Cities) boasts the largest inventory of advanced test systems in the country and is adept at configuring them to meet the customer’s specific test needs. The experienced staff and consultants have helped companies move hundreds of products through the FDA and other regulatory bodies' approval process. We have worked with small startups to many Fortune 500 companies over the years. Most of the company's sales are through word of mouth from satisfied customers and we like to say that our customers are our best salespeople. The company’s services include:

  • Test feasibility and design
  • Protocol development
  • Test implementation
  • Results recording and reporting
  • Data interpretation

The company develops new instrument, controls, and fixturing and engages in R&D projects on an ongoing basis. Many engineers on MDT's staff have been with us for ten years or more.
