...Hospital, and Harvard Medical School found that hackers could intercept patient information and reprogram the device, potentially endangering the patient by sending additional electrical signals to the heart. The researchers presented their findings last Wednesday, in anticipation of the publication of their paper, “Pacemakers and Implantable Cardiac Defibrillators: Software Radio Attacks and Zero-Power Defenses.” The study focused on the Medtronic Maximo, an IMD with wireless capabilities. These typically work over short distances and allow physicians to monitor the patients. “The wireless features of these devices are safety features. They provide...
...finding that she suffers from a mitochondrial disorder - a dysfunction in basic cell metabolism. Mitochondria serve as power generators for each cell in the body, converting food and oxygen into energy. There are a wide range of these disorders, causing symptoms that vary widely but can include muscle weakness, cardiac or liver disease, diabetes, developmental delays and susceptibility to infection. In Hannah's case, the vaccine court determined that the underlying dysfunction of her mitochondria put her at an increased risk of injury from vaccines...
...tiny sensors to monitor the structure's physical integrity. Or the steady vibrations of a beating human heart could be harvested to run a pacemaker. Not only is vibration energy free, but the power sources for devices it fuels wouldn't have to be replaced every few years--meaning cardiac patients wouldn't need their chests cut open periodically to replace the batteries in their pacemakers. "These are places where there's no source of power but plenty of vibrations," says Roy Freeland, CEO of the British vibration-power start-up Perpetuum. "You can just fit and forget...
Some doctors are skeptical. Cary W. Akins ’66, a cardiac surgeon at Mass. General Hospital, believes that a great deal more research must be conducted before scientists can begin to discuss possible surgical applications of this technology...
...good business. Fulga and his colleagues are tapping into the estimated $54 billion--a-year market of cardiac patients in need of treatment. The company projects that it will break even soon. "We want to be the Intel of cell therapy," says Fulga...
