APPEALS COURT STAYS INJUNCTION; MALLINCKRODT CAN CONTINUE TO SELL WarmTouch(*) BLANKETS IN U. S. ST. LOUIS, Mo., October 2, 1997 - Mallinckrodt Inc. (NYSE:MKG) can continue to sell its WarmTouch(*) patient warming blankets in the United States under a temporary stay of injunction issued yesterday by the federal court of appeals in Washington, D. C. Augustine, another manufacturer of patient warming systems, recently won a patent infringement decision against Mallinckrodt. This decision is being appealed by Mallinckrodt. The temporary stay is in effect until Augustine Medical submits its response - which is due October 7 - and the court determines whether the stay should be extended until Mallinckrodt's appeal is decided. "We are pleased that the court has taken this action," said Thomas R. Trotter, president of Mallinckrodt's Critical Care Division. "This will allow us to continue serving our hospital customers and to ensure that service to patients will not be disrupted." WarmTouch(*) blankets connect to blowers that fill the blankets with warm air. This creates a warming system that helps control patient body temperatures. Medical research has demonstrated patient benefits from such warming, including improved post-surgical recovery time and reduced incidences and severity of wound infection after surgery. Mallinckrodt Inc. serves healthcare and specialty chemicals markets worldwide. The company has four major businesses - pharmaceuticals, diagnostic imaging, respiratory care and specialty chemicals. The St. Louis, Missouri-based company, with fiscal 1997 net adjusted sales of $1.9 billion, operates in more than 100 countries.
