Wireless No Contact Heart Pump

[New Pump Doesn't Even Touch Blood]

Heart Disease is an ailment that millions of people suffer from, and live with on a daily basis. But this ailment can turn instantly lethal if not taken care of properly.

While most people are lucky enough that they can deal with this issue through just medication, exercise and diet control. However, for a large part of the population this disease is too extreme to be handled this easily.

For these people, the solution for this problem comes in the form of artificial methods of keeping their heart beating at a normal rhythm.

This involves placing a device inside the heart itself, which would regulate the flow of the blood through the organ, thus preventing extreme attacks.

The issue with most of these devices, however, is the fact that due to their placement inside one of the most sensitive organs in the body, they can also cause damage to the heart, by either encouraging the formation of clots, or damaging the red blood cells directly.

To take care of this issue, scientists at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland have created a new type of heart pump that doesn’t make contact with the blood at all.

This new pump operates with the help of a set of rings with the ability to contract and expand. These rings are placed around the aorta at precise locations.

This helps the system coordinate their movements to create pressure waves that help move the blood through the aorta in a regulated fashion.

To activate this feature, the rings use a Dielectric Electro Active Polymer (DEAP) which responds to electrical current induced via a magnetic field.

This magnetic field is created and operated using an external device, which removes the need for wires to penetrate the skin, thus reducing the changes of infections.

As you can guess, this technology is still under development, and very far away from human trails. However, the system is innovative enough that once it does become ready for use in humans, it will make regulating heart disease a lot more easier.
