Abstract
Steady flow hydrodynamic performance testing is performed on a valved prosthesis mounted in a test conduit. The system is configured with prescribed test condition inputs into control software. Upon test initiation, a steady flow pump is activated and automatically adjusts its flow based on the software logic to meet the prescribed first test condition. During forward flow pressure drop testing, the flow pump is automatically adjusted to achieve and hold a particular flow rate. During back flow leakage testing, the steady flow pump is automatically adjusted to achieve and hold a particular differential pressure across the test prosthesis while a flow rate of the leakage flow is measured. After a first test condition has been achieved, the system control software then automatically adjusts the pump flow rate to meet a second test condition. This process then continues until all conditions set by software inputs are evaluated.
