Test Instrument
Combining high-frequency performance and sample pressure control previously unachievable in heart valve durability testing!
Sales Promotions
Using proprietary ElectroForce controls and linear motor technology, the DuraPulse™ Heart Valve Test (HVT) instrument achieves smooth waveform fidelity and precise control for accelerated heart valve durability testing. Automatic PeakIQ™ control algorithms and independent test chambers ensure that established test conditions are maintained on each valve throughout the test. The DuraPulse HVT instrument provides testing to the ISO 5840 standard for heart valve durability assessment.
Key Features
- High frequency operation
- PeakIQ™ waveform control to prevent high pressure spikes on valve closing.
- Automatic controls (closed-loop feedback) to maintain test conditions throughout test
- Modular, independent control of each heart valve station
- Simplicity in transfer of heart valve device from durability test instrument to pulse duplicator
- 2, 4, or 6-station unit
- Reliable – 10 year warranty on linear motors
