Marlise Munoz, 33, who was about 22 weeks pregnant, had been on life support at John Peter Smith Hospital in Fort Worth since November 26 after falling unconscious. It is believed that she had a blood clot.
Her husband, Erick Munoz, had sought to remove her from life support, saying the foetus she had been forced to carry was withering inside her lifeless body.
A judge on Friday sided with the family in finding that Marlise was already legally dead and ordering the hospital to remove her ventilator, setting a Monday deadline.
Heather King, a lawyer for the Munoz family, said in a statement yesterday that life support had been removed and Marlise's body released to her husband.

In seeking to have Munoz disconnected from life support, lawyers for the family had argued that she was clinically dead, could no longer be considered a pregnant women and that the foetus she was carrying was severely damaged.
The lawyers also provided medical records they said show that the foetus suffered from oxygen deprivation and appears to have deformed lower extremities.
JPS Health Network, which runs the hospital, said it could not confirm that it had withdrawn life support, citing privacy policy.
The hospital had said earlier that it would remove "life-sustaining" treatment, but did not say when it would act.
Lawyers for the hospital had argued they were complying with a law that was intended to protect unborn children.
