Cardiac pacemaker

Implanted cardiac devices eventually accumulate a buildup of scar tissue which is a problem when the devices have to be replaced at the end of their battery life.  This tissue can foul electrodes; so, to address this problem, researchers at the Wyss research center of ETH Zurich have developed a protective cellulose membrane that reduces the accumulated fibers.  So far, this has only been proven in animal studies, but human trials will be coming soon.  MORE
