Half the size of a AAA battery, device requires no surgery, could last 14 years
(COLUMBUS, Ohio) May 2014 -- Doctors at The Ohio State University Wexner Medical Center are among the first in the country to implant a tiny, high-tech pacemaker directly into the heart of patients, and to do so without surgery. Only 24 millimeters in length, the pacemaker is fed through an artery in a patient's leg and, using tiny prongs, is attached into place on the heart.
"These devices are 90 percent smaller than current pacemakers and don't require wires or leads to be fed through the patient's chest in order to work," said Dr. John Hummel, an Ohio State cardiologist who is among those leading the investigation into the effectiveness of the new generation of pacemakers.
"Getting rid of the leads cuts down on complications considerably," said Ohio State's Dr. Ralph Augostini. "I think this is the biggest advancement in pacing technology in nearly 15 years."
Once in place, the pacemaker constantly monitors the condition of the patient and only activates when necessary. "That allows these devices to be extremely efficient," Hummel said. "With that kind of intermittent pacing, they could last as long as 14 years."
