Heart Valve Durability Tester Model MDV is the easiest-to-use tool for accelerated wear testing of artificial heart valves. Each tester runs only one valve at a time, allowing quick setup and avoiding troublesome interactions found in multi-unit machines. Test parameters are effortlessly adjusted on the touch-screen display. Outputs, such as pressure difference on valve, temperature, and even statistics for regulatory compliance, are continuously displayed.

This machine provides accelerated wear testing of a single heart valve specimen by pumping water through the valve and controlling the pressure difference across the valve. The pump is an unsealed piston-in-cylinder driven by a flexure-guided voice-coil actuator. Unsealed piston and cylinder eliminates wear and fatigue that would be present with bellows, diaphragms, or piston seals.

Control of the piston pump, temperature, and systemic pressure regulator are implemented by an embedded controller and operator-interface screen and keyboard on the testing station.

Test specimens can be easily removed and replaced in less than 5 minutes.

The machine is designed to facilitate customer compliance with test standards and regulatory guidance.

The clear plastic test section is easily removable and replaceable. The test section may be customized to accommodate the size and mounting method of the customer’s heart valve. Additional test sections can be designed and made by the customer or by Blockwise.
