Real-time statistics

Reliable actuator

Minimal maintenance

Model MDV Heart Valve Durability Tester

touchscreen HMI (human-machine interface) allows the user to enter parameters to control the test. Most parameters are electroncialy settable and can be changed while the test is running.

Differential-pressure statistics (relevant to regulatory guidance) are calculated and displayed immediately. Data can be exported at user specified intervals and sent to PC-based data acquisition software.

Auto-tuning mode automatically adjusts pump amplitude to achieve set heart valve differential pressure.

Calibration and checking of pressure, and temperature is very quick and easy. Specific screens for checking or calibrating walk the user through the process. The intuitive process reduces the likelihood of calibration mistakes.

The MDV machine requires no maintenance. The fluid portion of the machine can be cleaned with IPA or water.
