Patrick Dempsey wants to spend more time with his family after quitting 'Grey's Anatomy'.

The 49-year-old actor, who split from wife Jillian Fink in January after 15 years of marriage, is eager to focus on their three children, Talula, 13, and eight-year-old twin sons, Darby and Sullivan, and his passion for race-car driving.

Asked about his plans for the future, the heartthrob, who character Derek Shepherd has been killed off after 11 seasons on the medical drama, said: ''I'm focusing now on developing and racing and being a father to my children. Those are my priorities.''

But Patrick insists he has no plans to completely turn his back on Hollywood.

He told Entertainment Weekly magazine: ''I want to try something different. [But] is Derek so identifiable that I can't go on and be someone else?''

A source previously claimed the actor, who was also married to his former manager Rocky Parker for seven years from 1987 to 1994, was devastated about his split from make-up artist Jillian earlier this year, even though they had been ''living separate lives'' for some time.

The insider said: ''He was married and divorced before, and he has said he never wanted a divorce again because of his kids.''
