...Vacuum aspiration, used on most outpatients, is a new variation on the D. and C. method that makes abortion even easier. Performed only through the twelfth week of pregnancy, the operation consists of dilating the cervix, inserting a metal tube attached to a small vacuum pump and drawing off the fetal matter into a bottle. Discomfort during the five-minute operation, which often includes a quick curettage, is minimal. Pain is all but eliminated in a refinement of vacuum aspiration developed by Harvey Karman, a Los Angeles psychologist: for pregnancies of less than ten weeks' duration, doctors...
Tireless Lips. For all the theatrics, Enrico is that rare individual, a genuine musical prodigy-and on an instrument that demands physical maturity above all else. Many a child can scribble music or peck away at the piano. But an accomplished trumpeter needs a strong, well-developed diaphragm to pump a constant, high-pressure stream of breath into his horn. He needs powerful, tireless lips to shape his embouchure (or his "pucker," as Louis Armstrong liked to call it). Enrico...
Traditionally a parched period for Broadway, summer is the most fertile time of year for the London stage. American tourists crowd the city and producers pump new life into old attractions and unveil choice new ones. The most successful plays usually migrate to the U.S. Following is a current British sampler...
Installation of the pump was intricate business. Shanks, who was near death, was wheeled into the operating room at 7:15 p.m. Doctors opened his chest and slit the descending aorta, the downward trunk of the main artery leading from the heart. They then sewed the booster directly into the aorta, led the air hose out through the chest and connected it to the exterior tank. The procedure took five hours, but it was not until 5 a.m. that Shanks left the operating room; Kantrowitz kept him there until he was certain that the booster was doing...
...just that. A regulator unit connected to the heart muscle by wires kept the external pump in phase with the internal organ. As the heart's left ventricle, or major pumping chamber, contracted to force blood through the aorta, the external pump sucked air out of the outer tube, creating negative pressure that helped pull the blood out of the ventricle. Then, as the ventricle relaxed, the pump forced air back into the outer tube, increasing the pressure on the inner passage and forcing the blood through the aorta to the body...
