ATLANTA -- Thousands of lawsuits have been filed in the U.S. against the makers of surgical mesh used to treat incontinence and other pelvic problems in women.

The lawsuits accuse the companies of inadequate testing, failing to disclose potential risks and fraudulently promoting the mesh as a safe medical device. The manufacturers deny those allegations in court documents. Some companies have released statements saying they did extensive testing and insist their products are safe and effective.

While many women benefit from the mesh surgery, the Food and Drug Administration has warned some can suffer complications. But some doctors have said the warning -- and the lawsuits -- are misguided. The doctors blame inexperienced surgeons.

The mesh is used to support the bladder and other organs that slip because of age, childbirth or other reasons.
