Is it true that Bard was aware of issues with their IVC filter products?

Bard was aware of complications with their devices as early as 2004. Complaints were received that year about their filters breaking down, and migrating to other areas within the bodies, causing internal damage. As a result, the company commissioned a report that would come to be known as The Lehmann Report, being that it was conducted by independent consultant Dr. John Lehmann. The Lehman Report concluded that the Bard IVC Recovery filter generated more complications than its competitors.

Ultimately, The Lehman Report has emerged as proof that Bard was aware of issues with their devices and yet continued to market and sell them.
