A medical professor at the University of Minnesota received $6,000 from medical device maker Medtronic in exchange for testimony that urged lawmakers to continue funding medical research involving a bone growth product called Infuse, according to the New York Times. The newspaper reports that Dr. David W. Polly Jr. failed to disclose that he was working as a consultant for Medtronic when he testified before a Senate panel in 2006. Documents released by Senator Charles E. Grassley show that Polly received $1.14 million in fees and expenses from Medtronic from 2003 to 2007.
