Scientists from the University of Rochester Medical Center have demonstrated an implantable device called Rheos, aimed at
lowering pressure.
The device is being introduced under the skin near the collarbone and two electrodes are to the left and right carotid artery on the neck. It activates bar receptors that send signals to the brain of high pressure. In response to that the brain resists pressure, relaxes the blood vessels and suppresses the production of stress hormones. These changes alter the volume of blood, reducing the workload on the heart and reducing
blood pressure.
People with persistent arterial hypertension are at greater risk for stroke, myocardial infarction, heart failure, kidney disease and death. Any increase in pressure by 20 mmHg doubles the risk of stroke.
