BDC Laboratories’ RWT-4600i heart valve real-time wear tester is built on the VDT-3600i proven test platform, both in hardware and software, which facilitates the highly distinctive ability to operate both as a real-time test system and accelerated test system. The RWT-4600i tester is designed for evaluation of both transcatheter and surgical heart valve technologies and is in compliance with the latest ISO 5840 requirements. The test system has completely independent test stations, incorporating completely independent electromagnetic drivers, which allows each test station to be set totally independently in both displacement and frequency. The RWT-4600i real-time heart valve tester moves the fluid through the test valve using our proven RB-5 driver technology, equivalent to the VDT-3600i, to produce the opening and closing dynamics representative of clinical performance at both real-time frequencies and accelerated frequencies. The RWT-4600i heart valve real-time system is available in both a 6-station and 2-station platform.
The RWT-4600i valve real-time system is controlled and monitored by our proprietary Statys® RWT closed-loop control and monitoring test software. This software is equivalent to the established and proven Statys® VDT platform with many unique and patented features integrated, 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.
