来自《耶鲁大学开放课程：资本主义：成功、危机与改革第7集第7集》

If you watch one of these things it's--

手术是这样的
the patient is awake the whole time.

受术者全程都醒着
There is--basically what they do is,

他的动脉有些堵塞
there's a little blockage in one of your arteries,

医生们通常都会
they put a thing that looks sort of this,

把一根细导管
but a little smaller up your leg, they weave it up

从病人大腿动脉插入
until it gets to the right part in which there's a blockage,

直到堵塞部位
they have a balloon at the end of it,

导管尾部有个球囊
they have a little machine that blows up the balloon,

通过某种器械使它鼓胀
the balloon just presses against the wall of the artery,

变大的球囊便对动脉管内壁施压使其扩张
all the junk that was clogging it up goes whish

所有堵塞物就能被顺利冲走
and kind of floats away, we hope to wherever nirvana is,

感觉像是涅槃重生
