ATLANTIC CITY, N.J., Feb. 7, 2013 /PRNewswire/ -- The makers of a transvaginal mesh product that has sparked thousands of personal injury lawsuits ignored the advice of an expert who warned them that the product was dangerous, according to that expert's testimony in New Jersey Superior Court earlier this week. (Logo: http://photos.prnewswire.com/prnh/20130207/NY56537LOGO ) On Feb. 4, 2013, Dr. Uwe Klinge, a world-renowned expert on the biocompatibility of surgical mesh, told a jury about a talk he delivered in 2005 to Johnson & Johnson's Ethicon unit. During that talk, Dr. Klinge explained that, in order to be safe for patients, surgical mesh used in the pelvis would need to be very lightweight and have pores that are at least 1 millimeter in all directions. Later that year, Ethicon nevertheless began to market the Prolift vaginal mesh kit, a product with mesh that was larger and heavier than Dr. Klinge said it needed to be to be safe for patients. Dr. Klinge testified that he was not specifically involved with the development of the Prolift, but said that Ethicon executives were well aware of his surgical-mesh-safety research findings, and knew that the Prolift vaginal mesh product would lead to safety issues for patients. The trial at which Dr. Klinge delivered his testimony is the first of 1,800 transvaginal mesh lawsuits against Ethicon pending in New Jersey Superior Court to go to trial. As a representative of women who claim they've been harmed by vaginal mesh products, Rochelle Rottenstein, the Rottenstein Law Group's principal, implores women who believe they've been hurt by these implants to call the Rottenstein Law Group's offices for a free evaluation of their ability to file a lawsuit right away. "We're relieved that one of the Prolift cases has gone to trial, and look forward to helping many of the other women who've been seriously harmed by vaginal mesh products recover compensation for their injuries," Rottenstein says.
