Implant Recall

A hearing aid implant recall has sent the stock of a Switzerland-based implant maker tumbling. Shares of Sonova, the world's largest hearing aid maker, fell after the announcement that Advanced Bionics, which it owns, will recall its HiRes 90K cochlear-implant device. Two patients suffered from severe pain and overly loud sounds just days after activation of the device. Advanced had another recall six years ago.
