Wireless pump can save your heart


So far, if you suffered from a condition that required a heart pump, you would probably find yourself with a cable coming out of your body, connecting the pump to the battery and control unit, but all of that is about to change thanks to a team of Australian Scientists who decided to create a wireless system to feed artificial hearts, which in addition to being more practical and esthetic, can also greatly reduce the chances of infection.

These heart-simulating devices are applied to the patient when their heart is unable to pump the blood with the necessary blood pressure, and are usually used when a patient is waiting for a heart transplant or is in the process of recovering of a cardiac surgery.

Although these devices clearly save countless lives and are a marvel of modern medicine, they are not being used to their full potential. Due to the risks associated with these devices, very few are applied, and in the process many lives that could otherwise be spared are lost, the greater risk of this device and its application is the need for a cable connected to the pump to control it, leaving a body cavity, that in some cases of infection, can even lead to death.

The human body by nature is covered with bacteria and other microorganisms, which do not normally affect us because of one of our most efficient defense barriers, our skin. But when we open a breach in this barrier, and particularly in the area of an organ as crucial as the heart, we increase the risk levels of infection to almost 100 percent.

Concerned about this problem, the scientists decided to create a wireless energy transfer system, that avoids the need for a cable to enter the body. The system incorporates in the pump a copper resistance that eliminates the need for the existence of the cable.

On the outside of the body, there is only one transmitter and one battery that can be carried in a pocket or bag, which has a receptor resistance inside it, completely eliminating the dependence on the cables.

Although the system is still in a very embryonic stage, it is already able to reach 94 percent efficiency in the feeding of a heart pump, so with a few more adjustments, it will probably be within a short time available for surgical interventions.
