Defective Breast Implant Sales Draw Prison Term for French Executive - NYTimes.com

Jean-Claude Mas, 74, the founder of Poly Implant Prothèse, and four of his former employees were found guilty last spring of aggravated fraud after their company used a less expensive, industrial-grade silicone to fill implants for a decade. The implants ruptured at a much higher rate than the industry norm, leaking silicone into body tissues.

During the trial, which involved 7,400 civil plaintiffs and 300 lawyers, Mr. Mas acknowledged that his company had used a cheaper, unapproved product in its implants, but he argued that it was not harmful.
