Frictionless Substances and the Artificial Heart

[Bonker]

One of the biggest problems facing medical researchers who have been trying to come up with a decent way to run a good artificial heart has been the lack of substances with which to build the thing.

Barney Clark, the first artificial heart recipient, died of a stroke due to clotting in the device that eventually traveled to his brain. The new 'heart assist' pumps that are in use now that aid patients until their heart heals from an injury or disease, or until they can find a donor heart are made with certain ceramic materials that are so irregular that blood clots on them more rapidly than on smooth polymers and metals that were used in earlier devices.

The theory behind these is that because the surface is so rough, the blood clots that do form are much less likely to break off and work their way into a critical artery blockage. It seems to work, but these devices are *Very* high maintenance and require tubes and/or wires to extend from the chest cavity to power them.

This new material could have a profound effect on artificial organ research because, like the smooth muscle of the heart, blood won't clot on this stuff. If the research proves out, artificial heart devices can be made smaller, more powerful and less intrusive.

I just hope these guys realize this and will provide samples to research hospitals...
