2004年，Huffman先生将一块磁铁外科手术般地植入他的指尖里，来学习了解对于耳障患者人工耳蜗植入技术的应用。
In 2004, Mr. Huffman had a magnet surgically inserted into his fingertip to study the utility of cochlear implants for the hearing-impaired.
医学技术：第一个商业视网膜植入设备即将上市。也许它还很不完善，如同26年前的第一个耳蜗植入设备一样。
Medical technology: the first commercial retinal implant is about to go on sale. It may be crude, but so were the first cochlear implants, 26 years ago.
但是，就像耳蜗植入设备一样，刚刚推向市场的技术和20年后被广泛使用的技术是完全不同的。
But as cochlear implants have shown, the technology that first reaches the market is very different from what is available 20 years later.
