...catheter is a thin tube of Silastic (silicone rubber). To reach the brain's remote fastnesses, a plastic sleeve is inserted in the carotid artery in the neck and the catheter is threaded through it. Earlier catheters were often stopped by friction and could not always be guided into the desired path at a junction or around sharp curves. The new model, developed in research at Manhattan's Columbia-Presbyterian Medical Center and at the Weizmann Institute in Israel, has a magnetic tip. This can be made to oscillate in different directions under the control of an external...
...diagram), said Fournier, entered the top of Williams' skull, bounced off a bone near the pituitary gland and stopped in the temporal lobe of the brain. Another (No. 2) entered below the left eye and came to rest between the carotid artery and the jugular vein. One centimeter's deviation in almost any direction and this bullet could have caused fatal hemorrhaging. A third slug burrowed from the corner of the right eye into the jawbone. The fourth traveled from a point under the right nostril into the hard palate. The fifth bullet went through the roof...
...attacked by enemy operatives and left in a coma caused by a blood clot in midbrain. Since no conventional operation is possible, the high command approves a daring plan: a miniaturized submarine with a crew of shrunken specialists (led by Stephen Boyd and Raquel Welch) is injected into the carotid artery by hypodermic needle, with orders to navigate the bloodstream to the stricken area, where a surgeon (Arthur Kennedy) will excise the clot with an itsy-bitsy laser...
...survives the 3G power dive into the artery, and glides idyllically down a clear stream filled with pink and white corpuscles that look like house-sized globules of tapioca. Then all at once it is swept into a violent whirlpool set up by a fistula that unnaturally connects the carotid artery with the jugular vein. When the hemonauts come out of their spin, they are in the jugular, drifting inexorably away from the brain and toward the heart...
