Activities during the reporting period include test and evaluation of nuclear powered pacemakers; test, evaluation, and design of transcutaneous transformers to supply power for implanted blood pumps; and two exploratory projects aimed toward developing pulsatile coronary perfusion pumps and a circulation supporting periaortic pump. The nuclear powered pacemaker evaluation is designed to characterize the operating characteristic of such pacemakers over their anticipated five or more years of useful life. More than thirty pacemakers are implanted in dogs and six are being subjected to high stress bench tests. The transformer activities were initially to evaluate a transcutaneous transformer system developed by Stanford Research Institute using in vivo calf experiments, but later shifted from test and evaluation to development of a new transformer design. The hinged aortic pump was designed to be positioned around the descending thoracic aorta to provide prolonged circulatory support following cardiac surgery. A prototype pulsatile coronary perfusion pump was constructed and used in seven acute in vivo experiments. (GRA)
