The Breakthrough

Researchers from Cornell University have created a heart out of porous plastic foam that can pump more fluid compared to existing models for artificial hearts. This material is banking on its porosity; which allows air to flow for it to beat - much like how blood vessels flow to make the heart beat. The addition of a solid plastic coating seals the heart to protect it from leaking. The foam heart is made from a single piece of material, which will make it less susceptible to failure compared to models that are made with multiple parts. The heart can be seen in the video below

The Implications

Seen as a viable replacement for a heart, this model has yet to be tested in temperatures and conditions found in the human body. Since the foam heart tears when it over-inflates, more research will be done to optimize pumping speed and material design
