According to CBS News, a new study published in The Lancet has found success in clinical trials for an implantable device that helps lower high blood pressure. The new device, around the size of a paper clip, is called a coupler. It reduces strain on an artery by diverting blood to a nearby vein, thereby reducing the workload placed on the heart. Researchers gathered 83 patients, most of whom were in their late 50′s, all of whom take at least five blood pressure medications. Patients who received the implant experienced a 15 percent reduction in blood pressure and documented fewer hospital visits than those without the device.
