The sleeve that saves lives A Heart pumping device of the future


Transplants: Get rid of one organ and get new ones The word transplant could be very important to this research because we need to know what we are not gonna have to do anymore this would make the idea of 3d printing organs not important for this topic because we can keep it pumping without it and keep our own organs and not have the recovery time.

Blood clotting: when the blood start to stop flow of blood. The information about blood clotting can help people understand the possible scares of the use of these devices. This could help us understand why the possibilities of using this machine can have just as harmful effects as the possibilities of transplants.

Cardiac doctor: A heart doctor who diagnoses heart problems. In this topic which is about fixing heart problems you need to know what the problem is before they can fix it. A cardiologist is the doctor who will be diagnosing the people and telling them to get this done so if you don't know what the word means then you don't know how to get diagnosed with the illness this will fix.

Soft robot (I knew what it was but not how they are built): It's a soft exterior with small hard robotic finger like things that squeeze the heart that is about the thickness of average sized pencil lead strong all around the softIf this design goes through many people are going to be saved and this technology could be used in many other devices. If this technology works when will we start testing it on other organs?

Why does heart failure matter to Americans?

Heart failure has been impacting a lot of lives. Half the victims die within a year and it has been tied to over ten percent of deaths in 2009. According to the Center for Disease Control “One in 9 deaths in 2009 included heart failure as contributing cause.” This is important to not only the patients but this is also affecting family and friends. Anne Barnard, a newspaper editor for the Boston Globe newspaper tells us The New England Journal of Medicine says, “But the disease, which strikes about 550,000 Americans each year, still kills more than half of patients within five years of diagnosis.” The CDC also indicates that this issue with heart failure costs U. S. a lot of money each year. This is a taxpayer burden in the United States now. There is a machine being worked on by colleges right now to help solve the problems of heart failure.

What steps have been taken to get the robotic sheath used on humans?

The robot is being developed by students and faculty at Harvard University by testing it on pigs and other animals. Lindzi Wessel a Health Technology Specialist said ”Now, scientists have created a soft, robotic sheath that may someday help struggling hearts keep beating.” For a visual science magazine today did a really good job showing this machine in the video This soft robotic sheath can mimic the job of the muscle helping the heart beat. Later cardiologists plan on this robot replacing heart transplants all together for heart failure. The first author on this study from National University of Ireland Galway, Ellen Roche, Ph.D. says, “[these tests] were able to demonstrate the sleeves ability to restore the heart to 97 percent of its original cardiac output.” This shows how much the machine can do restoring strength to your heart, showing how it could help people with heart failure and also how it is being tested and developed on other animals.

How will the sleeve prevent deaths from heart failure?

This sleeve can prevent deaths from heart failure by pumping the blood through the body without having the risk of getting blood infections from implanting the devices into the body. Lindzi Wessel a journalist for the Science Magazine tells us, “Now, scientists have created a soft, robotic sheath that may someday help struggling hearts keep beating without that danger.” This shows us not only how the robot is gonna help people but also what it is and how it works. The study's first author Ellen Roche, a writer based at the National University of Ireland Galway, says, “The team's recently published their studies on pigs, in which they induced cardiac arrest in the animals then implanted the robotic device. They were able to demonstrate the sleeve's ability to restore the heart to 97 percent of its original cardiac output.” This shows how the device can restore power to the heart and how well it worked.

What can this device do that others can't?

This device is one of the only ones that would work from the outside of the heart instead of the inside. This would help prevent infection, blood clotting, and illness caused by the device coming in contact with the blood. As we see in Nikolay Nikolov and Lhadi Messaouden’s video, the device will be on the outside of the heart it will help prevent the infections caused by having a device in direct contact with the blood. The DNA : Daily News & Analysis tells us “The device could also be fine-tuned to twist and compress either the right or left heart ventricle - the cavities in the heart through which blood in pumped.” This can help many people by being able to have safe treatment when not able to get a heart transplant. This could change the way illnesses of all organs gets treated for ever.

Who will benefit from this?

Millions of people in the United States have heart failure and we spend over 30 million dollars a year on heart failure prevention and health care services, also one in nine deaths in the year of 2009 involved heart failure. The Center for Disease Control says “About 5.7 million adults in the United States have heart failure.” This heart pumping device could help a lot of people not only the people who would get it but also the people who would be paying the taxes going toward prevention and treatment. Lindzi Wessel a journalist for the science magazine tell us, “If patients in advanced stages of the disease can’t get transplants, doctors can implant devices that help the heart pump blood. But those devices put patients at risk for infection and clotting, thanks to valves and pumps that come into direct contact with blood.” This would help millions of people and put them at lower chances for infection or sickness from the device in their body because it doesn't come into contact with your blood.
