New York-based Priests for Life arranged for Joseph Maraachli, 13 months, to come to Cardinal Glennon Children's Medical Center after several other U.S. hospitals declined to treat the child.

The baby's case has received worldwide attention for the issues it raises about end-of-life care.

Joseph was transferred by air "despite the strongest possible medical advice to the contrary," according to a statement from London Health Sciences Centre in Ontario, Canada.

Doctors at Cardinal Glennon plan to make an announcement Tuesday about their plans for Joseph's care.

Joseph's parents had him discharged from the Canadian hospital where doctors said he had been treated for a progressive and fatal neurodegenerative disease. The Maraachlis wanted the baby to receive a tracheostomy, a hole cut into his throat in order to install a breathing machine. The Canadian hospital said the invasive procedure was not appropriate in Joseph's case because his disease is fatal.

Joseph was on breathing machines and a feeding tube at the Canadian hospital, where he has stayed since October.
