O'Donnell said the family had received offers of support from women's and human rights groups across the world in its quest for a public inquiry into Savita's death.
Savita died on October 28 at Galway University Hospital. She had been 17-week pregnant and was found to be miscarrying.
Praveen has said she asked repeatedly for a termination of the pregnancy but was refused on the grounds that the foetal heartbeat was still present and "this is a Catholic country".
The miscarriage lasted from October 21 to 24, according to Praveen. His wife contracted septicaemia and died on October 28.
