Mechanical and Physical Testing: Overview and Timeframe
**1. Mechanical Durability Testing
Tests Involved:
Fatigue Testing: Evaluate the material’s endurance under repetitive stress, simulating the cyclic loading experienced by heart valves .
Tensile and Compressive Strength: Measure the material’s resistance to stretching and compressing forces .
Flexibility and Elasticity: Determine how well the material can flex and return to its original shape without damage
Timeframe:
Duration: Typically, mechanical durability testing takes about 3-6 months, depending on the complexity of the tests and the need for long-term cyclic loading studies (50Wheel) (Blackbird).
**2. Hydrodynamic Performance Testing
Tests Involved:
Effective Orifice Area: Measure the valve’s opening size and flow characteristics to ensure efficient blood flow.
Regurgitation Testing: Assess the backflow of blood through the valve to ensure minimal leakage
Pressure Drop: Evaluate the pressure difference across the valve to ensure it does not impede blood flow .
Timeframe:
Duration: Hydrodynamic performance testing can be completed in approximately 2-4 months. This includes setting up test protocols, running tests under various conditions, and analyzing the data .
**3. Wear and Tear Testing
Tests Involved:
Abrasion Resistance: Test for material degradation due to friction and wear (50Wheel).
Long-term Simulation: Simulate the material’s performance over extended periods to ensure it withstands the conditions of use (50Wheel) (Blackbird).
Timeframe:
Duration: Wear and tear testing typically requires 3-6 months, as it involves long-term exposure and repeated testing to simulate years of use (Blackbird).
**4. Compliance with Regulatory Standards
Tests Involved:
ISO 5840 Compliance: Ensure that all mechanical tests meet the standards for heart valve devices, particularly those set by the ISO 5840 series .
Timeframe:
Duration: Documentation and compliance checks can add another 1-2 months to the overall timeline, depending on the complexity of the regulatory requirements .
Total Timeframe for Mechanical and Physical Testing
The combined timeframe for comprehensive mechanical and physical testing of Elast-Eon™ in a new heart valve product is estimated to be 8 to 12 months. This includes:
Fatigue Testing: 3-6 months
Hydrodynamic Performance: 2-4 months
Wear and Tear Testing: 3-6 months
Regulatory Compliance Documentation: 1-2 months
