Cochlear had a record 6 months of net profit--$77.7 million during the second half of 2012. The implant maker is bouncing back from losing more than $20 million in the second half of 2011, thanks to a recall of its bionic ear. The company sold a record 13,672 cochlear implants between July first and December 31 of last year. During that period, Cochlear began offering some new products in Korea, Japan and India.
