Dick Cheney & his heart pump - The dead walk the earth

By supplementing the amount of blood pumped through the body, Mr. Cheney’s pump allows him to do many things he would do with a working heart. Such patients can bicycle, golf, play tennis, drive, shop and generally do what they did before they developed severe heart failure. They need to take an anticoagulant, like warfarin (sold under the brand name Coumadin), and have blood tests to monitor the amount.
Mr. Cheney’s pump was placed near his heart. With most patients, a power line emerges about waist level and connects to a controller, a minicomputer that plugs into a pair of one-and-a-half-pound, 12-volt batteries. Patients wear a black mesh vest over their clothing that holds the controller and batteries.
