The primary manufacturer has been Johnson & Johnson and their wholly owned subsidiary called Depuy. Those are the companies that – or that’s the company that has manufactured most of the defective hips in the United States. They have another defective hip as well, which they are vigorously contesting as defective, but it’s a metal-on-metal model called the Pinnacle, and we have many people that have had the Pinnacle hip implant, metal-on-metal, that has had to be revised or taken out as well. Those patients, clients, have the same problems, high levels of cobalt and chromium in their system together with symptoms that interferes with their ability to enjoy life.

There are other manufacturers of metal-on-metal hips as well: Biomet, Smith & Nephew, Zimmer. So there are other manufacturers as well that have a smaller piece of the marketplace.
