Heart Valve Tester
The M6 is an accelerated durability tester designed for heart valves, with modular test sections which can be modified for a variety of medical devices and materials.
Overview
The M6 allows for up to six samples to be tested in six separate chambers by using a swash plate drive system. As the swash plate rotates, the bellows are compressed or extended causing fluid to flow through the test chamber. This allows for common fluid to be dispersed into separate chambers, which enables pressure and temperature stabilization.
The DC7000, a micro processor based controller allows for enhanced levels of experimental control and data capture. The DC7000 controls the speed, pressure and temperature, while recording the cycle count and allowing for graphing of the pressure signal by use of highly precise pressure transducers.
Developed to Test
- Heart Valves
- Septal Defect Closures
- Artificial Heart Bladders
- Membranes/Sheets
- Sutures/Clips
- Intra-aortic Balloons
The M6 has proven to be easy to maintain. This tester meets or exceeds all of the requirements called out in the ISO and AAMI standards documents for durability testing.
Advantages of this Tester
- Long history of high quality reputation in the industry.
- Proven results.
- Interchangeable test sections that allow for multiple sample sizes.
- Safety switches for temperature and pressure.
- Programmable cycle counts for automatic shut off.
Warranty
Limited one year on tester and controller, three months on precision bellows.
Extended warranties available upon request.

*Tester is capable of high frequencies under ideal conditions, but experimental data shows the reliability of test data and lifetime of the tester could be compromised at said frequencies. Sample design, size and compliance will determine the highest frequency at which the test can be performed with high confidence.
