BDC Laboratories’ VDT-3600i heart valve durability tester is a patented, revolutionary accelerated wear test (AWT) system designed for evaluation modern transcatheter and surgical aortic, mitral, pulmonary and tricuspid valve technologies to meet ISO 5840 requirements. The test system has 6 completely independent test stations, incorporating 6 completely independent electromagnetic drivers, which allows each test station to be set totally independently in both displacement and frequency. The VDT-3600i heart valve accelerated wear tester moves the fluid through the test valve using our proven RB-5 driver technology to produce the opening and closing dynamics representative of clinical performance at accelerated frequencies up to 50 Hz. The VDT-3600i heart valve durability system is available in both a 6-station and 2-station platform.
The VDT-3600i valve durability system is controlled and monitored by our proprietary Statys® VDT closed-loop control and monitoring test software. There are many unique and patented features integrated into the software package as highlighted below, including: driver excitation waveform definition and control, differential pressure waveform analyzer with a ISO criteria specific counter, closed-loop control on differential pressure loading, continual monitoring of the real-time differential pressures in all test stations and individual station alarm capabilities for monitoring of test conditions.
