A pyrrolesulfonamide compound having the following formula : . The method also includes monitoring flowing pressure in the first flowline and monitoring pressure in a first chamber of the displacement unit. Contact portions 5c and 5f are provided in the first insertion-detecting contact. The suture can then be tensioned to anchor the TFCC to the anchoring tissue. A coating of resin is then applied to the thermally bonded base before the composite material is passed through a forming apparatus where the material is heated over a convex support having the desired curvature for the slat and subsequently cooled.
