Arthur T Knackerbracket has found the following story:

ETH scientists have developed a special protective membrane made of cellulose that significantly reduces the build-up of fibrotic tissue around cardiac pacemaker implants, as reported in the current issue of the journal Biomaterials. Their development could greatly simplify surgical procedures for patients with cardiac pacemakers.

"Every pacemaker has to be replaced at some point. When this time comes, typically after about five years when the device's battery expires, the patient has to undergo surgery," explains Aldo Ferrari, Senior Scientist in ETH Professor Dimos Poulikakos's group and at Empa. "If too much fibrotic tissue has formed around the pacemaker, it complicates the procedure," he explains. In such cases, the surgeon has to cut into and remove this excess tissue. Not only does that prolong the operation, it also increases the risk of complications such as infection.

To overcome this issue, Ferrari and his colleagues at ETH Zurich spent the last few years developing a membrane with a special surface structure that is less conducive to the growth of fibrotic tissue than the smooth metal surface of pacemakers. This membrane has now been patented and Ferrari is working with fellow researchers at the Wyss Zurich research center, the University of Zurich and the German Center of Cardiovascular Research in Berlin to make it market-ready for use in patients.

    ... The authors all concurred that their inspiration was from the lead engineer on the project. When asked for comment the engineer replied, "I.... am.... GROOOOOT!"
