VDT-3600i
Heart Valve Durability System
BDC Laboratories’ VDT-3600i is a patented, revolutionary system for the accelerated wear testing (AWT) of heart valve technologies. It evaluates transcatheter and surgical aortic, mitral, pulmonary, and tricuspid valves in compliance with ISO 5840 requirements. Using our proven RB-5 driver technology, it replicates realistic valve dynamics at accelerated frequencies up to 50 Hz.
The VDT-3600i is controlled and monitored by our proprietary closed loop Statys® VDT software, featuring patented capabilities including driver excitation waveform definition and control, differential pressure waveform analysis, closed-loop control, continual monitoring of real-time differential pressures, and individual station alarms for monitoring test conditions.

-
- Patented arbitrary waveform driver excitation with integrated waveform creator to minimize pressure spike at accelerated frequencies
- Loading waveform analyzer for each station to determine test adherence to ISO 5840 with independent loading criteria cycle counter
- Closed-loop, autopilot driver control to user defined target differential pressure loading on each station
- Independent control of each test station’s excitation waveform, frequency, and stroke conditions
- Simultaneous continual monitoring and logging of real-time differential pressures for all test stations
- Real-time alarms and safeguards to protect both the system and test samples
- User-focused software environment to facilitate ease of system operation
Extend Your System
Optional accessories are available to extend your system’s capabilities. Add-ons can be purchased to support specific applications and configurations.
Software Accessories
ISO Criteria Waveform Analyzer
This software module evaluates each valve waveform against the ISO differential pressure loading criteria. After data processing, it displays statistical results alongside the overlaid waveforms. A secondary cycle counter tracks the total number of loading cycles that satisfy the ISO differential loading pressure requirements.
Arbitrary Waveform Creator
This module lets the user define and save custom motion waveforms. Each station motor can load and run these waveforms, allowing the user to optimize opening and closing performance for a particular test valve.
Alarm Output Trigger
Configure a digital signal to trigger external hardware in the case of a system alarm.
Synchronized Snapshot Data Acquisition
To synchronize the accelerated leaflet kinematics of the heart valve with the differential pressure loading, the synchronized snapshot data feature includes a TTL output signal that aligns in time with waveform data acquisition, enabling input to a high-speed camera system.
Hardware Accessories
6x Temperature Monitor
To monitor and document fluid temperature independently at each test station, this system supports up to six temperature probes compared to the factory-standard single probe. This accessory includes both hardware and software components to enable multi-channel monitoring and control.
Low Pressure Regulator
Designed for high-resolution applications like the VDT-3600i, this precision pressure regulator offers control sensitivity of 1/8″ water column and a pressure range of 0-10 psi. A balanced supply valve ensures consistent, reliable accuracy to maintain the desired system set point despite changes in supply pressure or flow conditions.
Silent Air Compressor
The whisper-quiet air compressor operates at a noise level of just 30 dB and includes an inline regulator and moisture trap. It features a convenient carry handle on top with an operating pressure range of 55-85 psi.
Silicone Mock Vessels
BDC Laboratories offers certified silicone mock vessels in straight, curved, bifurcated, or customer-defined configurations for mounting stents, stent grafts, transcatheter heart valve frames, and other endovascular implants. We fabricate and certify mock vessels to a specified diametric compliance or wall thickness and perform certification at various pulse pressures to meet your specific requirements (e.g., 160 mmHg/80 mmHg).
System Drip Tray
Drip tray designed to integrated with the test apparatus and capture all fluid leaks.
