Former VP Dick Cheney has gone bionic. During a recent heart surgery, doctors implanted a ventricular assist device to augment Cheney's failing ticker. But it also gives his critics another punchline to work with; because the device moves blood continuously, it doesn't mimic the pulsating rhythm of the heartbeat. Technically speaking, Dick Cheney no longer has a pulse. Insert Darth Vader comparisons here.
So-called keyhole surgery techniques have come a long way in recent decades, but a lack of dexterity and freedom of movement means sometimes surgeons can't get the job done, and that means they have to go in the old fashioned way: Straight through the breastbone.
