This is similar system to that used by some heart pacemaker systems, but these only report back technical information about the condition of the implant, rather than gather extensive data about the condition of the patient.
Dr Amin Karami told a meeting of the American Heart Association that pacemaker batteries needed to be replaced approximately every seven years.
After undergoing another surgery to replace Medtronic leads--wires connecting the pacemaker to the heart--with ones from Guidant, Davis sued both the hospital system and Haugland, charging medical malpractice and complaining that the second surgery could have been prevented.
By treating the cells as heart cells would be treated and using a pacemaker to help them learn how to pump, they grew into a heart that could pump -- essentially rebuilding the organ's interior.
Their team showed that the device could generate 18 times the amount of energy needed to power a pacemaker using a normal heart beat, according to Dr. Karami.
The designers now want to test the device on a real heart and build it into a commercial pacemaker.
An experimental pacemaker in testing that can be installed through a catheter without surgery could help open up new markets for heart gear in India, where there are few doctors trained to implant current pacemaker devices.
Several manufacturers expect their pacemaker devices to win marketing approval for heart failure patients by the end of the year.
ATLANTA, Georgia (CNN) -- A pacemaker device could help up to half of all heart failure patients live a more active life, researchers told the American College of Cardiology Tuesday.
In one of those incidents, heart surgeon Charles Sciolaro says he had a patient who requested a pacemaker made by St.
When Dr. Taylor built a rat heart in a lab dish five years ago, she used a pacemaker to make it beat.

Amin Karami, an aerospace engineering research fellow, presented data at the American Heart Association annual conference in November showing an experimental energy harvester can convert the energy from the beating of a heart into enough usable electrical energy to, in theory, operate a pacemaker.
The new pacemaker uses three wires, or leads, which are threaded into both sides of the heart to help it pump more efficiently.
