Medical device testing is often aimed at evaluating a medical device’s risk of failure in patients, which is critical when device failure could result in serious harm or death. Durability testing is particularly important when implantable medical devices are intended for multi-year use and experience repeated stress and strain cycles. Cardiovascular devices such as stents, heart valves and other endovascular devices not only experience substantial stress or strain during each heartbeat cycle, but they must resist this loading repeatedly for approximately 400 million cycles for a 10-year lifetime, and 600 million for 15-year lifetime. In vitro fatigue testing to evaluate device durability against heartbeat loading is crucial for device manufacturers to gain regulatory approval such as per US FDA, European MDR and Chinese FDA requirements.

ElectroForce TestBench configurations were designed with component testing in mind, and thanks to their modular approach, a wide array of configurations and performance capabilities are possible.  These instruments can be configured with 200N or 400N ElectroForce linear motors mounted on a horizontal baseplate and include multi-channel and multi-axis options.

Reaction brackets are pre-designed to allow attachment of components or the test specimen to the mounting baseplate. In addition, a saline bath can be provided as an environmental option. By selecting the proper baseplate and ElectroForce® motor packages, a variety of testing needs can be addressed.


Key Features

  • Superior performance: choose parameters for your test protocol without compromising accuracy, including force, displacement, frequency, and wave shape (loading profile)
  • Controllability: precisely characterize different materials by controlling specific experimental parameters, including load, displacement, and strain control (with the Digital Video Extensometer (DVE))
  • Tailored for specific research needs: optional configurations for horizontal or vertical mounting, accessories such as saline baths, and multi-axis loading, including additional ElectroForce linear motors, extended stroke actuators, and rotary motors
