SFT-1000 Heart Valve Steady Flow System

The SFT-1000 heart valve steady flow hydrodynamic test system is another revolutionary and patented heart valve test instrument from BDC Laboratories. The SFT-1000 achieves all ISO 5840 outlined test conditions for both forward flow pressure drop and back flow leakage assessments in a streamlined and extremely efficient manner. One key manner this is accomplished is by testing both conditions, forward flow and back flow, without the need to remove the heart valve from the test system. The SFT-1000 is available either in a manual configuration or as a fully automated test apparatus. When fully automated, testing of a heart valve to all forward flow and back flow conditions takes only minutes.

The accompanying Statys® SFT control and monitoring software provides a comprehensive interface to program all the specific forward flow and back pressure test conditions. With high fidelity closed-loop pump control, the SFT-1000 heart valve steady flow test system will automatically execute each condition precisely and automatically cycle through all flow rates until the heart valve prosthesis evaluation is complete. An automated pdf-format report is generated upon completion of a test to provide clear and error-free documented results.
