Jeffrey Greiner – An Introduction to Cochlear Implants




An accomplished medical technology executive with many years of experience in the field, Jeffrey Greiner most recently served as the chief executive officer of Advanced Bionics. In this capacity, Greiner oversaw the manufacture and sale of several neuromodulation products, including cochlear implants.

Defined as a medical device that directly stimulates the auditory nerve in the ear, cochlear implants have proven highly effective in helping deaf people hear. The devices actually act as prostheses for damaged or depleted hair cells in the inner ear.




Cochlear implants consist of two distinct pieces: the external parts and the implant. The external parts of a cochlear implant include a microphone, a processor, and a transmitter, which picks up auditory signals from the environment and transmits them to a surgically implanted receiver. The implant takes the sound signals and uses them to send a series of electrical impulses to the fibers of the auditory nerve, which then travel to the brain for processing. These man-made devices have proved quite successful for post-lingually deafened adults as well as children born deaf.

Baseball Strategy: The Hit and Run

Jeffrey Greiner is a former executive at Advanced Bionics in Valencia, California. Prior to his time at Advanced Bionics, Jeff Greiner was a scholar athlete on the baseball team at the United States Air Force Academy. As a former collegiate baseball player, Greiner has coached Pony League baseball in Southern California. Coaches, like business executives, must understand their field deeply in order to win. For example, an aggressive baseball strategist regularly looks for an opportunity to deploy the hit and run. The hit-and-run strategy has base runners running before the pitch, with the expectation that the batter will put the ball on the ground and in play.

Because the hit and run is a situational strategy, it is easy to misuse. A hit and run should not be activated when there are two outs. The objective of the strategy is to advance the base runners, while in effect, sacrificing the batter. If a hit and run is employed with two outs, the inning will be over and no offensive benefit will be gained. A good situation for the hit and run is when there are no outs, runners on first and third, and an average hitter at the plate. A hit and run will help the offense avoid a double play, while scoring the runner on third with any hit on the ground.

The hit and run play is just one of many nuances of the game of baseball. Any baseball coach who expects to win will master this among many others. The same is true for business executives. In order to win, leaders will have to master the nuances of their particular fields of competition.
