A Noble Invention for One-Sided Heart failure
By MedTech Outlook | Friday, November 30, 2018
Literally, not metaphorically, scientists have found a way to mend a broken heart. Heart failure consists of various categories like affecting the heart muscle and valves, heart’s electrical system and the coronary arteries. For the general population, the risk of sudden heart failure has increased over time irrespective of the person’s age.
In order to prevent such catastrophic events, researchers from Harvard University and Boston Children’s Hospital have developed a noble robotic device that fits around the heart to support patients with one-sided heart failure. This minimally invasive cardiac assist device does not contact with blood instead it squeezes it from the outside, and apparently reduces the chances of clotting thereby obliterating the need for blood thinner medications which are risky.
The researchers have implanted a rigid brace into the intraventricular septum that provide resistance against soft actuators that cup the affected ventricle to pump blood effectively on the defective side of the heart. Contraction takes place in the ventricular chamber due to the expansion of the actuators as they push against the ventricular wall and pull against the septal brace. This leads to the sufficient flowing of blood without any causes of clotting as the actuators relax, particularly moulded elastic bands assist heart’s wall to its original position. The rigid brace keeps the septum intact and relieves the healthy side of the heart from the burden of the other. Moreover, the researchers have successfully tested the device in an animal model and the team is working to refine the device to make it suitable for human patients.
