Research output: Chapter in Book/Report/Conference proceedingConference contribution


An electric motor driven roller-screw total articial heart (TAH) has been developed at the Pennsyvania State University and implanted succesfully in nine calves. The TAH consists of a brushless DC motor with roller-screw drive actuating two blood pumps. A device employing 100 cc pumps has been successfully implanted in eight calve, and survival has been as long as 194 days. Recently, a completely implantable version, using clinical size (70 cc) blood pumps, a miniaturized internal electronics package and a transcutaneous energy transmission system, has been successfully implanted. System failure that occured have been evaluated, and appropriate design modifications have been made.
