Symbion terminated Dr. Robert K. Jarvik.

Jarvik was chairman and chief executive of the Salt Lake City-based firm that manufactures and markets the artificial hearts he designed. In a release, the company said: “The board sincerely appreciates his many contributions to the company and recognizes his outstanding scientific accomplishments. The board wishes to emphasize that Jarvik’s termination did not result from the recent tender offer for the company’s common shares.” E. M. Warburg Pincus & Co., a New York-based venture capital company, had launched a tender offer to gain majority control of Symbion, and Jarvik tendered his 600,000 shares.
