A court hearing over organ donation rules is on hold after the Delaware County girl at the center of the lawsuit received a lung transplant.
Sarah Murnaghan, 10, is recovering after receiving adult lungs this week at Children's Hospital of Philadelphia.
Her parents had sued over national transplant rules that say children under 12 must wait for pediatric lungs, which rarely become available.
U.S. District Judge Michael Baylson ordered that Sarah be put on the adult list, where her deteriorating health made her a priority and quickly led to a quick match.
Meanwhile, the national transplant network has created a special appeals process for about 30 other children who need lungs.
Baylson has canceled Friday's hearing, but says he'll revisit the issue next month if necessary, for either Sarah or another Philadelphia patient, 11-year-old Javier Acosta of New York.
