SCI-MED <SMLS> BOARD AGREES TO BRISTOL<BMY>DEAL Sci-Med Life Systems Inc said its directors approved a previously proposed agreement of merger with Bristol-Myers Co. The proposed transaction is subject to completion of a due diligence investigation, including a review by Bristol-Myers of a patent infringement suit served on Sci-Med by Advanced Cardiovascular Systems Inc on March 31, 1987. Bristol-Myers has the right to call off the agreement under certain circumstances, it said. Sci-Med said it continues to believe the patent suit is without merit.
