Heart failure is a condition where the heart is still working but it can’t pump enough blood which is needed to the body.  If affects approximately 5.7 million American and 50% of those who develop it die within 5 years of diagnosis. Today some of the options to treat it are mechanical pumps called ventricular assist devices (VADs), which pump blood the ventricles into the aorta and then heart transplant.

To overcome this issue in the patient’s, Engineers at Harvard University are working on a soft robotic that might help get human beings’ hearts pumping blood nicely again. This heart sleeve fits around a heart and enables it to beat, probably establishing new remedy alternatives for people suffering from heart failure.

The soft sleeve twists and compresses in synch with a beating heart, augmenting cardiovascular functions weakened by the heart failure. It reduces the risk of clotting and eliminates the need for a patient to take potentially dangerous blood thinner medications.

“This research demonstrates that the growing field of smooth robotics may be carried out to scientific wishes and probably reduce a load of coronary heart sickness and improve the fine of lifestyles for patients,” said ellen t. Roche, the paper’s first writer and former Ph.D. student on the Harvard john a. Paulson faculty of engineering and applied sciences (seas) and the Wyss institute of biologically stimulated engineering at Harvard university.

The team is working on an air-powered sleeve that can be slipped over the heart to assist in blood flow way to the way constantly inflates and deflates. The group observes at the tender robotic explains, “the robot sleeve uses compressed air to strength artificial silicone muscle groups that compress and twist, mimicking the actions of the everyday human coronary heart.”

Roche said, “the heart sleeve can be customized as the need of the patient.” It can be tuned as per the condition of the patients to give more assistance on the side which they are getting the problem. Similarly, the pressure of the actuators can also be increased or decreased over time, as the patient’s condition involves. This device is completely different from other ventricular assist devices because it doesn’t actually in contact with the blood.

“The cardiac area had grown to become far from concept of developing heart compression as opposed to blood-pumping VADs because of technological barriers, but now with advancements in soft robotics it is time to show returned,” stated frank Pigula, a cardiothoracic health care provider and co-corresponding creator at the study, who became formerly clinical director of pediatric cardiac surgical procedure at Boston children’s clinic and is now a college member at college of Louisville and division leader of pediatric cardiac surgical procedure at Kosair children’s health facility. “The majority with heart failure do nonetheless have some characteristic left; sooner or later the robotic sleeve may also assist their heart to work well sufficient that they’re nice of existence may be restored.”

“This research is actually significant in the meanwhile because increasingly more humans are surviving heart assaults and ending up with heart failure,” said Roche. “Soft robot devices are ideally fitted to engage with soft tissue and give help that could assist with augmentation of characteristic, and potentially even recuperation and restoration.”

Before practicing this device on the human heart which could risk the life of the patient, it has been tested on animals which hold potential for those who are in need of a transplant or for those who are in cardiac recovery.
