Jean-Claude Mas, the founder of French company PIP, which distributed defective breast implants around the world, has been sentenced to four years in prison for fraud.
Jean-Claude Mas was also fined 75,000 euros ($101,000) by a court in Marseille.
He will remain at liberty until a French court hears an appeal lodged by his lawyer.
PIP’s sale of faulty implants caused a global health scare which affected about 300,000 women in 65 countries.
The company was found to have used sub-standard silicone gel – rather than medical-grade silicone – which the result that many implants ruptured.
Apart from Jean-Claude Mas, four other former PIP executives were convicted and given lesser sentences.
With more than 5,000 women registered as plaintiffs in the case, and about 300 lawyers, the trial was considered one of the biggest in French legal history.
The health scare came to public attention in 2011 when the French government recommended that women have PIP implants removed due to an abnormally high rupture rate.
The issue of whether the sub-standard silicone used in the implants posed any danger was not resolved by the trial, AFP news agency notes.
Jean-Claude Mas, 74, showed no sign of emotion as sentence was passed. His lawyer, Yves Haddad, blamed the severity of the sentence on pressure generated by the media, and said he would appeal, meaning that Mas will remain at liberty until the outcome of a further hearing.
He and the others had all admitted to fraud.
PIP’s director-general was sentenced to three years in prison, two of which were suspended.
The company’s head of quality control received two years, one of them suspended, and the head of research and development was sentenced to 18 months, suspended.
Throughout the trial, Jean-Claude Mas had denied the silicone used was harmful while all but one of the other defendants said they had not been aware of the risks.
When an implant ruptures, the silicone gel filling can leak into the body. Some women will not notice anything at all, and there is no evidence of an increased cancer risk.
However, it can result in the formation of scar tissue that can change the shape and feel of the breast. The gel can be an irritant, causing pain and inflammation. It can also be more difficult to remove an implant once it has ruptured.
France’s Health Products Agency (ANSM) has to date registered more than 7,500 implant ruptures and 3,000 cases of undesirable effects, mainly inflammations, among the 30,000 women using PIP products in France.
