...developed. This is what I wrote back then: "McMahon has developed his own method that he calls intrauterine cranial decompression. He arranges the fetus so that he can remove it feet first. Before the skull emerges, he 'collapses' it by inserting a three-millimeter instrument known as a cannula and extracting its fluid. By keeping the fetus intact, he says, he runs less risk of internal injury to the woman...
...joints, through a hollow tube. In the diskectomy technique, a stainless-steel tube, guided by X ray, is slipped into the incision until the tip of the instrument rests against the disk. Next the surgeon threads a combination cutting-suction device the diameter of a pencil lead down the cannula, pushes it gently into the center of the disk and steps on a floor pedal. Suction draws disk material, which has the texture of crab meat, into a porthole near the probe's tip. There it is neatly sliced off with a tiny pneumatically driven guillotine-like blade that slides...
...from similar procedures performed in clinics in New York and other states where abortion is legal. Vacuum aspiration, as usually done, requires dilation of the cervix under local anesthesia. Menstrual extraction requires little or no dilation in most cases. Instead, a thin (diameter: 4 mm.), flexible plastic tube, or cannula, is inserted through the cervix and into the uterus, and most of the uterine lining is then removed by means of suction or a specially designed syringe...
...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 use a thin plastic tube that is smaller in diameter than the more commonly used cannula. This avoids the dilatation process entirely...
...excessive size) and squeeze the urethra shut by simple pressure, or it may become cancerous. At the Millard Fillmore and Veterans Administration hospitals in Buffalo, Dr. Ward Soanes and Dr. Maurice J. Gonder have devised special instruments and an ingenious technique. They give light anesthesia and introduce the cold cannula through the urethra. To make sure of the placement, the surgeon's finger can check the position of a button on the side of the probe as it nears the prostate. The cold is then turned on. The patient needs a catheter (a plastic tube) through the urethra...
