英语翻译
Just seven years ago the Jarvik-7 artificial heart was being cheered as the model of human creativeness.The sight of Barney Clark-alive and conscious after trading his diseased heart for met-al-and-plastic pump -convinced the press the public and many doctors that the future had arrived.It hadn't.After monitoring production of the Jarvik-7 and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S.Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them.Last week the agency cancelled its earlier approval effectively banning ( 禁止 ) the device .
The recall may hurt Symbion Inc.maker of the Jarvik-7 but it won't end the request for an artificial heart.One problem with the banned model is that the tubes connecting it to an external power source created a passage infection.Inventors are now working on new devices that would be fully placed along with a tiny power pack in the patient's chest.The first sample products aren't expected for another 10 or 20 years.But some people are already worrying that they'11 work- and that America's overextended healthcare programs Will lose a precious $ 2.5 billion to $ 5 billion a year providing them for a relatively few dying patients.If such expenditures( 开支)cut into funding for more basic care the net effect could actually be a decline in the nation's health.
