Tokos Medical President to Resign Dec. 31 : Transition: Craig T. Davenport directed the company while its pregnancy monitoring device was questioned.

Craig T. Davenport, president of Tokos Medical Corp., said Thursday that he is resigning to devote more time to personal matters.

Davenport, 41, said his decision to leave the manufacturer of pregnancy monitoring devices was made after months of soul-searching and consultations with Robert F. Byrnes, Tokos chairman and chief executive. Tokos monitors detect the onset of premature labor.

Describing his departure as “very amicable,” Davenport will remain an outside director of the six-member board, leaving Byrnes as the company’s only inside director.

“I started to reflect on the company’s and my needs. I think it is in the company’s best interest and mine to get out of it,” Davenport said. “I still remain dedicated to Tokos.”

Davenport steered the company through a rocky two years, during which the Tokos monitor was questioned by the American College of Obstetricians and Gynecologists and attacked by stock short sellers. Its shares took repeated tumbles on lower-than-expected revenue.

Davenport’s duties as president and chief operating officer will be shared by Byrnes; John R. Bason, president of the subsidiary, Tokos Clinical Services Corp., and Terry Bayer, head of Tokos’ newly established obstetrics and pediatric managed care unit.

Davenport’s resignation is effective Dec. 31.

He declined to say if he has a position at another company lined up, but said he expects to find “opportunity in different projects.”
