...leaders a chance to bask in Selassie's reflected glory. Trinidad-Tobago's Prime Minister Eric Williams, who extended the original invitation to Selassie two years ago, kept his visitor visible and on the go, attending receptions, laying wreaths and setting cornerstones. In the small, ornate parliamentary chamber of the country's "Red House," Selassie pleased everyone by calling for closer ties between "the two great peoples" of Ethiopia and Trinidad-Tobago...
...With a ten-inch incision across his chest, DeRudder was hooked up to a heart-lung machine. And then, as five cameras recorded every step, the surgeons opened his left auricle. They replaced the diseased valve, but even this promised little. The left ventricle, the main pumping chamber, which does more than half the heart's work, was too badly diseased. Standing ready in the operating room was a team of doctors and engineers with the one device that might help: a "half-heart" to assist the left ventricle by partially bypassing it (see diagram). An instrument based...
...left auricle. Then he took the other tube and sewed it into a hole in the side of the aorta. At DeRudder's chest wall, the round plaque holding these tubes, together with smaller tubes for priming and flushing with saline solution, was attached to a hemispheric chamber 3 in. in diameter. Inside this was a Silastic diaphragm, which alternately generated pressure and exerted suction as it was worked to and fro by an external pump...
Pull & Push. Oxygenated blood from DeRudder's lungs then flowed normally into his left auricle. From there, up to 80% of it was drawn by suction into the pump chamber, held for an instant by a check valve, then pushed by the pressure of the pump's downstroke into the aorta, which supplies all the body's arteries. The rest took nature's course. It passed through the newly implanted artificial mitral valve into the ventricle, which continued to beat, and out into the aorta...
...standard in U.S. justice. The Bill of Rights-basically, the Constitution's first eight amendments-was written in the 18th century when there were no police forces. At the time, the trial itself was the critical confrontation between the state and the accused. Mindful of the British Star Chamber, the Constitution's framers ringed American trials with safeguards-almost none of which serve to protect the suspect from the time he is picked up by the police until days or even weeks later, when he appears before a judge...
