Researchers have developed the world's smallest, minimally invasive pacemaker. New cardiac devices are small enough to be delivered through blood vessels into the heart, via an incision in the thigh. It's delivered via a catheter through the femoral vein and then positioned inside the right ventricle of the heart.
The findings also showed that the Micra TPS—about the size of a large vitamin—met safety and effectiveness endpoints with wide margins. In a recent international clinical trial, it was successfully implanted in 99.2 percent of the 725 patients, and 96 percent of patients experienced zero complications -- 51 percent less than normal procedures.
