Structural Analysis Of Leaflet For Mechancial Heart Valve
Objective:
A heart valve manufacturer in the USA needed a come-up with an optimally designed heart valve.
The most important component of a heart valve is a leaflet which regulates the flow of blood. The leaflet is hinged at the broad-end to the inside of the cylinder which sits inside the artery. Since it is a mechanical heart valve working without an external power source it is important to design the leaflet to reduce drag and mechanical losses at the hinges.

Methodology:
Finite element models were generated using parametric method to allow easy modification of the design parameters for optimal design. The profile of the leaflet was generated using ‘computational fluid dynamics’ to reduce drag. Several different mounting methods were studied to arrive at the optimal hinge mechanism.
The manufacturer was able to launch a unique valve into the market in record time.
