Brian H. Dovey has resigned as president of Survival Technology, the Bethesda developer and manufacturer of emergency medical-care products, effective Feb. 15.

Dovey, who will remain on the company's board of directors, will become president of the surgical products division of the Pennsylvania health-care company Rorer Group.

Dovey said he was "not looking at all" when he received a phone call from a management recruiter for the Rorer position. He said the move "represents a real improvement in my career" because he will now head five companies, "each one about the same size or larger than Survival Technology."

Rorer Group's special products division consists of five operating subsidiaries with total sales of approximately $120 million last year. Survival Technology's sales for last year were approximately $20 million.

Dr. Stanley J. Sarnoff, chairman of Survival Technology's board of directors, will become president of the company. Cabot R. Caskie, vice president and chief financial officer, has been promoted to executive vice president.

Caskie has been with Survival Technology for seven years and was formerly head of the company's outpatient cardiac-care operations. Prior to joining the company, he was vice president of Systems Technology Associates Inc.

In addition, Robert Katzen has been promoted to vice president and controller. Douglas J. Greenwold has joined the company as vice president of the outpatient cardiac-care operations.
